3. In the process of releasing water to flow downward, what direction does the water flow in the home pool (counterclockwise). Explain the reason: The rotation direction of the Northern Hemisphere region is counterclockwise.

Imagine that in the Southern Hemisphere, water flows in a clockwise direction.

When the earth rotates, if the earth's axis is not tilted, will there be four seasons in the orbital plane of the vertical revolution? Why? - There will be no change of seasons.

Because, if that is the case, the sun only shines directly on the equator, and the regions around the region get solar heat energy to save the difference in the months without the season.

What is the situation like in the area where we live? - There is only one season of the year, and there is only spring or autumn now.

There is a proverb that "after eating the winter solstice meal, the day grows a line." Why?

On the winter solstice, the Northern Hemisphere has the shortest daylight hours. After the winter solstice, the direct point of the sun moves north, and the daylight hours in the Northern Hemisphere increase day by day.

1, B 2, D 3, flow down no direction, you describe it wrong, 4, there will be no change of the four seasons, because the inclination will constantly change the light surface that is, change the temperature, the temperature is different, and once it is not tilted, the temperature of each ground crack will remain the same, and the season will be consistent. 5. The winter solstice is December 22, after which the direct sun point moves north from the Tropic of Cancer (until the summer day, it returns to the south from the Tropic of Cancer and wants to move).

Latitude 23°26 north and south

North. 3.The Northern Hemisphere is counterclockwise and the Southern Hemisphere is clockwise (this is related to the geostrophic deflection force)4

There will be no change of seasons, because the occurrence of the four seasons is caused by the change of the altitude angle of the sun, and the rotation of the earth causes the direct latitude of the sun to move, and the altitude angle of the sun at noon in various places, so there are four seasons, and the reason is that there is still a yellow-red angle (that is, the earth's axis has an angle of inclination).

5.The winter solstice is the day with the longest nights and the shortest daylight hours of the year (only in the Northern Hemisphere).

6.This question is not sufficient.

It's all wrong. The dividing line between the eastern and western hemispheres is a coil of meridians of 20°W and 160°E, and to cross the eastern and western hemispheres, you must stand on one of the meridians (regardless of latitude).

What does 150°-180° east longitude mean?

If you are allowed to go all the way north from Linyi, you can't go back to the starting point.

If you go all the way north from Linyi, after reaching the North Pole, go south along the opposite meridian, and after reaching the South Pole, you can return to the starting point along the meridian of Linyi to the north.

If you are asked to go all the way north from Linyi, after reaching the North Pole, follow the same path and go back.

1. The boy's statement is incorrect, because the prime meridian is at 20 degrees and 160 degrees west longitude.

The girl is not right for the same reason.

2No, go south at the North Pole.

Really. It seems to be standing on the line

1. The meridian of 160 degrees east longitude and 20 degrees west longitude is the dividing line between the eastern and western hemispheres, think about it!

The boy's statement was wrong. Because the dividing line between the eastern and western hemispheres is 20°W (west longitude) and 160°E (east longitude), only standing on these two meridians is to cross the eastern and western hemispheres. If the girl is standing at 150° E, she is in the Eastern Hemisphere, and if she is now between 160° and 180°, she is in the Western Hemisphere, because the dividing line between the Eastern and Western Hemispheres is 20°W (west longitude) and 160°E (east longitude).

1.National Day is in June (direct to the equator) and before December (direct to the Tropic of Capricorn), when the sun moves directly southward, hence d

The 22nd of the month is the autumn equinox, after the Army Day, the sun directly moves from the equator to the Tropic of Capricorn, so the days in the southern hemisphere become longer, so choose A

After the summer solstice, the sunlight moves south from the Tropic of Cancer on June 22 - December 21 The national holiday is October 1 so it is d

The polar day in the Northern Hemisphere occurs in the summer Army Day is between June 22 and September 23, which happens to be summer, so choose A

1.According to the 2nd equinox and 2nd solstice, because the sun shines directly on the southern hemisphere, the time is after the autumnal equinox, and because it continues to move southward, this time is definitely not on the day of the winter solstice, but the day before the winter solstice.

2.The longest day in the Northern Hemisphere is the summer solstice (June 22), the above answer, you see which date is closest to June 22, which is the longest day, Army Day 39 days, Labor Day 53 days, National Day 100 days, the Spring Festival don't need me to count anymore, right?

The above are all on the map.

This data is ** on the map, and the final result is subject to the latest data on the map.

a, on January 1, the direct sun was in the southern hemisphere but moved northward On January 10, the direct sun was in the northern hemisphere and moved south.

c, on May 1, the direct point of the sun was in the hemisphere and moved northward.

So the answer is d The sun is at the equator at the time of the autumnal equinox around September 23 On the 11th National Day, the direct sun has moved to the southern hemisphere and has been moving southward, and it is not until the winter solstice around December 22 that the direct sun will move to the northern hemisphere.

2.The longest day in the Northern Hemisphere is on the day of the summer solstice, around June 22, when the day is the longest and the night is shortest, so you can find the closest holiday to June 22.

aAugust 1 b Generally in January or February cMay 1 d October 1 Therefore, Labor Day is the closest to the summer solstice and the longest day.

Question 1: On December 22, the sun hits the Tropic of Capricorn and then moves north, on March 21, the sun hits the equator and then continues to move north, on June 22, the sun hits the Tropic of Cancer and then moves south, and on September 23, the sun hits the equator and then moves south. a, the sun shines directly on the southern hemisphere on New Year's Day, but moves northward; b, the sun shines directly on the northern hemisphere on Teacher's Day and moves southward; c, Labor Day the sun directly hits the northern hemisphere and moves northward, only d fits the topic.

Question 2: The relatively long days in the Northern Hemisphere prove that the sun is directly hitting the Northern Hemisphere, and June 22 is the summer solstice day in the Northern Hemisphere, and the day is the longest, so the closer to June 22, the longer the days in the Northern Hemisphere, so choose A

Topographic characteristics of the Indochina Peninsula: the mountains and rivers are alternately and vertically distributed, the lower reaches of the large rivers and the estuary are alluvial plains, and the climate characteristics of the main tropical monsoon climate of the Indochina Peninsula are characterized by high temperature throughout the year, with obvious rain and drought in the two seasons, and the mountains and rivers are alternately distributed in tandem and the distribution of mountains and rivers is obvious.

Topographical features of the Malay Archipelago:

1. The terrain is rugged and the mountains are rugged.

2. The plains are less turbulent and the rivers are rapid.

3. Multiple volcanoes**.

The Malay Archipelago has a tropical rainforest climate and a tropical monsoon climate, with high temperature and rain throughout the year, and crops are sown and harvested at any time.

The water systems of the Malay Archipelago are short and turbulent, and the rivers have a high rate of ground erosion.

1。When it is winter in the Northern Hemisphere, the direct point of the sun is the Tropic of Capricorn, and the polar night phenomenon occurs in the Arctic Circle, and the days of the year are the shortest in the year in the Tropic of Cancer and the areas north of it, and the days get shorter the further north you go. Bringing these four places to the map, Mohe is in the northernmost place, so choose D

It is irrelevant to the D option, first exclude it, and put it first, and see that the time of day near the North Pole is the polar day, and you associate the physical reflection map, the incident angle of the sun near the North Pole is very large, so the reflection angle is the same. The ground absorbs very little, and the polar day phenomenon is also short, so it is cold.

3。On the summer solstice in the Northern Hemisphere, the sun shines directly on the Tropic of Capricorn, and the days in and north of the Tropic of Capricorn are the largest in the year, and the polar day phenomenon occurs in the Arctic Circle. This is basic knowledge, and if you don't understand it, just memorize it.

4。Are you sure you got it right? The question is not displayed completely, and the answer cannot be given. When you say that you choose the South Pole, I can only understand that the house is surrounded by the North on all sides. If so, because the South Pole is the southernmost point of the Earth, so standing on the South Pole, then he will be surrounded by the North.

1d, because on the day of the winter solstice, the day is long and the night is short, the North Pole will appear polar night, and the Mohe River in Heilongjiang is the northernmost point of our country, so it is the shortest day in our country.

2c, because the North Pole is in the extreme north, the sun does not shine directly, and it is difficult for the ground to absorb heat 3a, and on the day of the summer solstice, the sun directly hits the Tropic of Capricorn, and the North Pole will have a polar day phenomenon, and the South Pole will have a polar night phenomenon. The winter solstice is the opposite.

4a, because at the south pole there is only the north direction, at the north pole it is only in the south direction, the intersection of the equator and the zero degree meridian and the intersection of the equator and the 180 degrees of longitude have the southeast, northwest direction, this problem can be completely eliminated by the method of elimination.

1.Drilling and sampling of ice can help us understand the earth's climate change since the formation of the Antarctic ice, as well as the impact of human activities on the environment, the impact of global warming on the rate of melting of the ice sheet, the species of organisms under the ice, and mineral deposits.

2.Because of the progress of the times, people's needs are more and more, and they are no longer satisfied with the present, so people need to continue to open up and enrich their spiritual world. At the same time, we need to constantly understand the world we live in.

There are many places in the Arctic that are worth exploring. For example, the global climate can be studied from the poles. Studying the evolution of the earth, many resources can be exploited, and can be of high military value.

1.The Earth's axis, a, is not real.

2.Latitude , equator.

3.Meridian.

1. The Earth's axis North Pole is not.

It is the oblique axis of the earth, also known as the axis of rotation of the earth. Refers to the axis around which the Earth's rotation rotates, with the North End intersecting with the Earth's surface being the North Pole and the South Pole at the intersection of the South End and the Earth's surface. ）

2. Latitude (transverse) equator.

3. Warp.

1.In the figure, the AB axis is (the Earth's axis), and the north pole is pointing near the North Star. Is it real?

Not real).
