3 simple geography questions in senior 1

1. c(a, Leo does not belong to the solar system; b, d, nebulae are not of the solar system; ）

2. d (a, solid ball is wrong; b. In the process of reaching the earth, solar radiation is blocked by the earth's atmosphere and cosmic matter, so the energy reaching the earth's surface is not most of it, but the impact on the earth and human beings is huge; c. Mainly concentrated in the visible light part).

3. c (the higher the latitude, the greater the impact).

This is a multiple-choice question in the 2010 national college entrance examination new course standard paper, it can be said that this question is a bit beyond the scope of geography, it should be said that most people do this question wrong, and the scoring rate is very low.

This question should be seen in particular".

First".

1.The decrease in the number of births does not lead to a rapid decrease in the number of laborers, and the total number of the labor force is still rising, so it is excluded.

2.Gender composition is not related to the birth rate, so it is excluded.

3.The age composition of the labour force is fixed, 18 to 65 years old, so d is excluded.

So you can only choose B.

The explanation of this option on the Internet probably means that the decrease in the number of births, that is, the decrease in the number of new babies, and the decrease in the number of babies will directly affect the baby-related industries, such as preschool education, infant products, and so on.

a.Northern Hemisphere Mediterranean climate.

The west coast of the continent of 30 degrees --- 40 degrees has a Mediterranean climate, which is alternately controlled by the subtropical high pressure belt and the westerly wind belt.

The west coast of the continent of 40 degrees --- 60 degrees is a temperate oceanic climate, which is controlled by the westerly wind belt all year round.

1. [Answer] C

Analysis] This title is the original picture of the textbook, which belongs to the basic knowledge. See page 35 of the high school geography textbook of the People's Education Edition.

2. [Answer] a

Analysis] From the global temperature statistics (textbook), the temperature is on an upward trend, that is, the temperature will lead to the melting of ice and snow in the Arctic Ocean, and a large stream of cold seawater will move southward, leading to the strengthening of the cold current and the weakening of the warm current in the middle and high latitudes, and the increase in global temperature will lead to a smaller temperature difference between the high latitudes and the low latitudes, and the prevailing wind will weaken and the warm current will weaken in the middle latitudes.

3. [Answer] a

First of all, the school needs to be arranged as close to the residential area as possible to facilitate services and have a larger service group. Second, schools should stay away from noisy and polluted environments such as chemical plants. In this case, the school cannot be arranged in vegetable fields and rice fields, which is contrary to common sense.

4. [Answer] a

Analysis] Because the air pressure value is a b c, the wind direction is a to b and then to c. Make the tangent line of the q point, and then make the perpendicular line of the tangent line, according to the direction of the tangent, the wind direction is northwest wind (westerly wind, northerly wind are right). Q is in a trough of low pressure, controlled by the updraft, and the rising airflow is cold and cloudy and rainy, so Q should be rainy weather.

Based on the above judgments, choose A

5. [Answer] D

Analysis] The same method as the fourth question is to make the perpendicular line of the tangent of the q point. And because the water flow flows from the high outlet to the low place, the water flow at the Q point is judged to flow in the southeast direction according to the perpendicular line. Because it is a contour map, it can be judged that the terrain in the map is a valley, and the water flow should be eastward.

Therefore choose D6. [Answer] D

Analysis] The figure is a top view of the North Pole, and because a is the morning line, and the earth rotates from west to east, it is judged that the left side of the morning and dusk line is the day hemisphere, the right side is the night hemisphere, and the polar night appears in the Arctic Circle, so it is the winter solstice day of the northern hemisphere.

7. [Answer] a

Analysis] According to the morning line A and the map in the map, it can be seen that Beijing, Shanghai and Guangzhou are all in the day hemisphere, and only Lanzhou is still in the night hemisphere, so Lanzhou is about to sunrise.

8. [Answer] D

Analysis] Because the left side of the earth's morning and dusk line in the figure is the day hemisphere, and when the earth is in the right position (the north pole is above, the south pole is below), the direction of revolution is from west to east, so the direction of revolution is .

There is less time, so write relatively briefly, and you can ask me again if you have any questions. Hopefully

It is affected by the geostrophic deflection force.

Geostrophic deflection force" – the force acting on a horizontally moving object due to the rotation of the earth, referred to as the deflection force. It only arises when the object is moving relative to the ground (it does not actually exist), and can only change (horizontally) the direction of the object's motion, not the rate of the object's motion.

Geostrophic deflection forces are to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, and of course these right-to-left are relative to the forward direction, and the following is the situation in the Northern Hemisphere.

1.Since the angular velocity of each latitude is the same, when flying from north to south, the circle of the south is large, so the linear velocity is large, so a small linear velocity in the north is slower than the linear velocity of the south, so it deviates to the right due to inertia. It's the same with going north, from a fast place to a slow place, the speed is 'ahead', and the direction of progress is also deviated to the right.

2.Fly along the latitude to the east and west, at this time, because the direction of gravity points to the center of the earth, and the direction of the latitude circle points to the center of the circle is not the center of the earth, you can think about it, so because of this angle, the centripetal force can not completely cancel out the centrifugal force that you rotate around the center of the circle of the parallel, so a synthesis, it will also deviate to the right.

3.The equator is not subject to geostrophic deflection precisely because the center of the earth is exactly the center of the circle in which the latitudinal circle rotates, and the two coincide, and gravity can cancel out the outward force. Finally, the geostrophic deflection force is greatest at the north and south poles.

The Yangtze River is located in the northern hemisphere and flows from west to east, so the geostrophic deflection force is to the south, and the impact force of the water flow on the south bank is greater.

This is due to the cause of the rotation of the Earth, here there is an offset of an object moving horizontally along the surface of the Earth, the cause of the deflection: the geostrophic deflection force resulting from the rotation of the Earth. Deflection Rules:

The northern hemisphere is biased to the right, the north and south spheres are biased to the left, and the equator is not biased, and the higher the latitude, the greater the deflection. Impact: Rivers:

Northern Hemisphere: Scouring on the right bank, siltation on the left bank. (The river is straight, and the opposite is true for the north and south balls.)

This knowledge point is in the chapter on the rotation of the earth.

Hello landlord, first of all, I'm glad to answer for you! This problem should be explained in conjunction with the geostrophic deflection force, judging the direction of this force one day by the mouth, it is said that the northern hemisphere is biased to the right, the southern hemisphere is biased to the left, to be specific, you imagine yourself with your back to the river or the direction of the wind, and then you look at the right hand pointing to that side, which side is affected by this force! Let's go back to this topic, first of all, the Yangtze River is in the northern hemisphere, so it is biased to the right, imagine that your back is facing the Yangtze River, and the right hand is pointing to the south, so the river will flow to the south, so the south erosion is more serious, and the north is more serious siltation!

Glad to be able to answer for the landlord!

Affected by the geostrophic deflection force, the river on the south bank of the Yangtze River is seriously scoured, so the embankment on the south bank is the focus of protection.

And not the North Shore. The south bank is seriously eroded by flowing water and is not suitable for building a sand quarry, while the north bank is a sand quarry because of the accumulation of flowing water.

The ground floor is not right.

is due to the fact that the separation of gravity is southward.

Therefore, the south bank is generally seriously washed by rivers.

According to the geostrophic deflection force, the water flow on the south bank of the Yangtze River is stronger than that on the north bank and the flow speed is faster, so the river on the south bank is seriously scoured. It has nothing to do with the wind, it has something to do with the erosion of flowing water.

Hehe--- Yangtze River is located in the northern hemisphere.

Therefore, the river water will be affected by the gravity of the earth to the south, and flow to the south--- so the south bank is seriously scoured.

Affected by the wind, the south bank was heavily scoured.

Because the Yangtze River flows from east to west, and the Yangtze River is located in the northern hemisphere, due to the action of the earth's rotation and gravity, the south bank of the Yangtze River is more seriously scoured than the north bank, and if it is a southern hemisphere river, the north bank is seriously scoured.

This is affected by the geostrophic deflection force. In the southern hemisphere, affected by the geostrophic deflection force, to the left, and the northern hemisphere is to the right, the Yangtze River is located in the northern hemisphere, affected by the geostrophic deflection force, in the process of traveling, it is natural to shift to the right, and the right of the Yangtze River is south, since the water flow of the Yangtze River is to the south, the south bank bears the water flow, the impact is large, the erosion is naturally serious, and the north bank is more sediment deposits.

b I just did it the day before yesterday on my test paper.

Affected by the geostrophic deflection force, the river flows to the right in the northern hemisphere and left in the southern hemisphere.

1，a.The farthest celestial body ever observed by humans is about 15 billion kilometers away from the Earth; This is a false statement, we ourselves live in the universe.

c.Various celestial bodies exist in isolation in the universe: false, various celestial bodies have a mutual gravitational pull, as illustrated by the Earth's revolution and rotation.

d.The most basic celestial bodies in the universe are stars and planets, which should be stars and nebulae.

2.Earth-Moon and Solar System; Chang'e-2 is not only active in the Earth-Moon system.

The shape of the Moon is very malleable, so the phases of the Moon are constantly changing when seen on Earth: the Moon does not change, it only changes because it is blockedThe Moon itself does not emit light, and we see the bright Moon as a result of its reflection of the sun's light:

To CChang'e-2 has been a celestial object since it was loaded onto the rocket: a celestial body is a material body in space.

d.Chang'e-2 moved from the Earth's orbit to the Moon's orbit, and the hierarchy of the celestial system did not change: there was a change, the solar system to the Earth-Moon system.

4.There was originally a planet between Earth and Mars, and at some point a giant asteroid hit the planet and caused the planet to shatter, because Jupiter's gravity formed an asteroid belt before Jupiter and Mars.

First of all, the first question A should measure the distance in the universe in light years, C must not exist in isolation (the solar system is an example), and d is the most basic is stars and nebulae.

In the second question, the moon revolves around the earth, which belongs to one kind, and the satellite revolves around the moon is another (it can be imagined that the earth is the sun, the moon is a planet orbiting the sun, Chang'e-2 is a satellite orbiting the planet, the planet and the sun form the earth-solar system, and the satellite and the star form the earth-moon system, just an analogy for easy understanding).

In the third question, the reason for the moon phase is that the earthlings see that the moon is partially changed by the sun, and c is called a celestial body when it is launched into space.

Question 4: I think you're wrong, Mars should be located between the Earth's orbit and Jupiter's orbit.

The first question a should be a light year, not a kilometer, c is not isolated, d the basic objects are nebulae and stars.

The second question, if the earth's orbit is drawn is second-order, and Chang'e orbiting the moon also forms a first-order celestial system, therefore; The phase change of the moon can be seen on the earth, a is not true; Chang'e-2 is a celestial body when it is brought into space, not in the atmosphere or on the ground, so c is not right; Chang'e-2 orbiting the Earth is a system, and orbiting the Moon is a celestial system, so D is wrong;

Finally, instead of the Earth being located between the orbits of Mars and Jupiter, the asteroid belt is located between the orbits of Mars and Jupiter.

I don't understand, it's too much.

Wrong. In the southern hemisphere, it is clear that the westerly drifting coast is surrounded by ice caps, where did the desert come from.

Right. North Pacific: Kuril Cold Current + Japanese Warm Current = Hokkaido Fishing Grounds.

North Atlantic: Gulf Stream + Labrador Snap = Newfoundland Fisheries; North Atlantic Warm Current + East Greenland Cold Current = North Sea Fisheries.

Wrong. Tokyo to New York route: Pacific Ocean - Panama Canal - Atlantic Ocean.

The passing currents are: Japan Warm Current, North Pacific Current, California Cold, Gulf Current, Gulf Current.

And the Canarian cold snap is northeast of the Atlantic, which is obviously wrong.

Right. The cold snap between 40 and 60 degrees north latitude, the Canary cold snap, and further north are at most south of 45°.

To sum up, choose

Choose C. As shown in the figure, the red dot in the figure represents Shanghai, then the system is located in the east direction of Shanghai (that is, Shanghai is located in the west direction of the system), then the wind direction of Shanghai is shown by the blue arrow in the figure, and the wind blows from southeast to northwest, so it is a southeast wind. (Note the definition of wind direction:.)

Wind direction refers to the direction of the wind, that is, the direction of the arrow of the wind direction is the direction of the wind).

Question 1 is A. Analysis: Beijing time is the district time, the district time of the eighth eastern district (120° east longitude).

There are two possible 180° meridians or the meridian with 0 points in local time, and one meridian in the figure is 90°E, then this meridian is 0 point longitude in the two date lines, and the other is 180° longitude. At this time, it is 0:00 at 90°E, and at 120°E, it is 2:00 on September 2. International Standard Time (UTC) refers to the zone time in the central time zone, which is the local time of the 0° meridian (London time), so the UTC should be at 6 p.m. on September 1.

Select D for the second question. Analysis: There is a 180° meridian in the picture, and the OP meridian is also the morning line, so the OP should be 6 o'clock.

According to common sense, the longitude of the OP is either 45W or 45E. After hypothetical extrapolation, we conclude that the central pole of the graph is the North Pole, op should be 45°E, then the meridian at 0 point in local time should be 45°W, then the meridian at 0 point (45°W) is a new day in the range from east to 180° longitude, and it is a new day to cross the longitude of 225°, accounting for 5 8 of the world's 360°, so D is chosen

If you don't understand, you can continue to ask.
