Urgent!! Sophomore Geography, Problems with the Movement of the Earth

The first option d is because the land pole is 2w, 47n), so the water pole should be the other point that corresponds to it. This point is 178 degrees e, 47 degrees s

The second option, CA, says that the place is located in the Atlantic Ocean, which is wrong. Because 178 degrees east longitude is in the Pacific Ocean b says b the position is within the plate, the earth's crust is stable, and the place is located on the Pacific ** circle, so it is not stable d says that the place is located in the eastern and southern hemispheres. 178 degrees east longitude is not the Eastern Hemisphere

And the Western Hemisphere, . .The Eastern Hemisphere is the region between 20 degrees west longitude and 160 degrees east longitude.

The third option d is the longest river in France.

The fourth option a, the continental hemisphere is mostly in the northern hemisphere, and the approximate position is calculated according to the continental pole in the problem, when the night hemisphere overlaps with the continental hemisphere the most. It's the winter solstice, and only a is right at this time. B is obviously wrong, C summer is the news bully. d There will be low pressure in the summer.

The second question upstairs must be wrong. It's common sense. My fourth question is different from his, and I can't be sure.

d Passing through the center of the earth and coming out of the earth, the point that comes out is another pole.

d It can be known according to the position of latitude and longitude found in the previous question.

d Temperate marine climate It certainly doesn't freeze in winter Precipitation is uniform throughout the year and there is no river water swelling in summer The Royal River is actually the Loire River The transliteration is different About the sediment content It may be that there is a strong tide in the estuary area that causes the river to have a relatively large sediment content I don't understand this very difficult problem.

d First of all, the most overlapping is definitely the winter in the northern hemisphere, the direct sun is in the southern hemisphere, 2w 47n is the pole of the continental hemisphere, not the center point, if you want to overlap, the most overlapping is definitely the winter solstice in the northern hemisphere, the direct sun is (23 degrees 36 minutes s 178e), Wuhu longitude is about the same as Beijing, at this time it should be eight o'clock in the morning in winter, and it will not be dark at night.

When the whole world is on the same date, the direct point of the sun should be on the 0 degree longitude, and the natural date line coincides with the international date line, and the Tarim River is a summer flood, and the northern hemisphere winter is a cyclone in western Europe, and it is correct that this cyclone is an extratropical frontal cyclone, and the causes are complex.

It's really okay, it's hard to be.

It is 5:30 a.m. at point A, so AB is the morning line, and A is not far from the equator because the sun rises at 6 o'clock at the equator. The inference that ab is the morning line also gives that the direction of rotation of the earth rotates from left to right, so this diagram is just a grid spread out on the graticule.

It is 5:30 in place of A, and B is 15 degrees east of A, so it is 6:30 in time of place B, and the equator will be between Ab (the intersection of the equator and the morning line is 6:

00) A is in the Northern Hemisphere, and point B is in the Southern Hemisphere. A o'clock 5:30 is on the morning line, so it's 5:

30 sunrise, then sunset time = 24-5:30 = 18:30, so the day length is 13 hours, the day length and the night are short The sun hits the northern hemisphere directly.

In this figure, when point A coincides with point C, that is, the morning and dusk lines are perpendicular to the equator (coincides with the meridians), and now the angle between AC is degrees (1 2*15), so the direct sun is at the point, so this phenomenon will only occur when the sun is direct next time. In fact, having said so much, I made it with experience, and when I see the sunrise time in place A, you can know that place A must be between the lines of cancer. So the answer is c

As for the second question, it means.

When point b is at the end of the red line, to reach this point is when the sun is direct, that is, a needs to move north to the Tropic of Capricorn, and then move south to the equator and then, if you don't calculate the time, analogous from the equator on March 21 to the equator on September 23 is half a year apart (the direct shot is the direct equator).

So the time is about half a year.

1.The Earth's equatorial plane and the Earth's orbital plane have a degree of angle (i.e., the yellow-red angle), but the position of the Sun is parallel to the orbital plane (to be precise, the Sun is at a focal point of the orbital plane), so when the Sun directly hits the Tropic of Capricorn, it will produce an angle with the equatorial plane, which is exactly the same as the Yellow-Red angle, at a straight angle.

2.Yes, the day and night are equally divided in the late years of the equatorial region, but only the spring and autumn equinox is too lacking, and the height of the hidden sun is 90 degrees, and the summer and winter solstice reach the smallest degree of the year.

Hello! The linear velocity at any point on Earth is equal to the velocity above the equator multiplied by COSA (A is the local geographic latitude).

So the velocity of an object at the equator is v, then the linear velocity of 60° north latitude is v*cos60°=1 2v

Hope it helps, hopefully.

The rotation of the Earth. Enclose.

Central axis. That is. Axis. Target.

Angular velocity. It's the same, linear velocity.

is the angular velocity multiplied by the radius, which is the distance from this point to the earth's axis, and the radius at the equator is.

Earth's radius. The radius of 60 degrees north latitude forms a triangle with the earth's axis and the earth's radius, the angle between the radius of 60 degrees and the earth's radius is 60 degrees, and the hypotenuse is the earth's radius, that is, the rotation radius of 60 is the earth's radius multiplied by co

s60, which is 1 2

Question 3: First of all, the height of the sun at noon is 90 degrees, and there are 2 times, so it must be between the Tropic of Capricorn! Then c and d can be ruled out. The minimum noon sun height is more than 50 degrees, that is, the latitude difference (because it is a place in the Northern Hemisphere, the latitude difference on the winter solstice is the latitude of the place plus the latitude of the Tropic of Capricorn) is more than 30 degrees!

If it's 10°N, it only adds up to more than 30! It can only be 10°N! Choose A

In question 4, you can see that m is located in the saddle of the two peaks, that is, between the two direct sunlight. 20°N does have 2 direct sunlight, respectively before the summer solstice and after the summer solstice, then the lowest moment where M is located is the farthest from 20°N (at this time, the direct point is north of M), naturally M is the summer solstice, that is, 2 is the ...... of the summer solsticeAnd so on, the sun height is the lowest at 4 noon, which is the winter solstice. 1 is the spring equinox, and 3 is the autumn equinox.

Then the spring equinox should be a is established, the summer solstice will naturally not pass the Mid-Autumn Festival, and the autumn equinox cannot welcome the New Year, and the winter solstice is obviously not the ...... of "Tanabata".Choose A

As shown in the figure, the solar altitude angle reaches 90° at the two peaks, indicating that there must be direct sunlight in this place, then the place can only be between the Tropic of Cancer, so c d. is excludedAnd because this place is in the northern hemisphere, the minimum solar altitude should be winter, so 4 is winter, we can substitute a and b with the solar altitude angle formula, and get that the time of substitution a is 56...5 When substituting B, it can be seen from the figure that it should be more than 50 degrees, so choose A.

At 10 degrees latitude, there are two direct rays, one from spring to summer and one from summer to autumn, with the lowest solar altitude angle in winter and followed by summer. So 1234 is spring, summer, autumn and winter. So you should choose A

Hey......If you don't use what you've learned, you forget everything you learn.
