Senior 1 Geography. Urgent solution. 10

Genesis of the Himalayas: The Eurasian and Indian Ocean plates are formed by the mutual compression of each other.

Global Atmospheric Environmental Problems:1The greenhouse effect (i.e. global warming) – due to excessive CO2 emissions (mostly due to human burning of fossil fuels), but also deforestation.

The solution is to change the structure of energy consumption.

Reforestation. Increase international cooperation.

2.Acid rain --- caused by excessive emissions of gases such as NO2 and SO2, most of which originate from industrial production

The solution is to change the structure of energy consumption.

Increase investment in science and technology.

3.The ozone hole (note, not a hole, the ozone layer has not been destroyed to the point of being empty) – the reason is that the freon emits too much and reacts the ozone out.

The solution: to reduce freon emissions (there is no better and more effective way to do so).

Eurasian plate movement squeezes.

The problem of the global atmosphere is the greenhouse effect, which is caused by excessive carbon dioxide emissions, and the causes of the Himalayas: the Eurasian plate and the Indian Ocean plate are quickly squeezing each other.

Continental plate movements.

The climate is warming and glaciers are melting.

Massive emissions of greenhouse gases (factories, too many people).

The cause is the movement of the block to squeeze and rise, and the problem of the global atmosphere is the greenhouse effect, which is the emission of carbon dioxide, which is a greenhouse gas that can cause global warming and cause many changes and disasters on the earth.

7. The map is a map of the northern hemisphere, the center is the North Pole, the local time in B is 6 o'clock, there is a longitude difference of 110° between B and A, and the local time difference of 15° longitude is 1 hour, and the local time difference of 110° longitude is 7 hours and 20 minutes. The local time is 13:20

8. The picture is a side view, and the first place is located on the ** meridian of the equinoxical day hemisphere, and the local time is 12 o'clock.

9. The figure is a map of the southern hemisphere, the shaded part represents the 6th, the non-shaded part represents the 7th, the local time in C is 0 o'clock, and the time in B is 180° longitude. The longitude of place C is 0°, the longitude difference between place A and place C is 70°, and the local time difference is 4 hours and 40 minutes. It is 0:00 in place C, and the time in place A is 4:40

The intersection of the morning line and the equator is 6 o'clock, and there is 20 + 90 = 110 degrees to point A, corresponding to a time difference of 7 hours and 20 minutes. Therefore, local time in A is 6 + 7 hours and 20 minutes = 13:20

The Earth turns from west to east, separated by 15 degrees, one hour earlier than west, 1 degree is 4 minutes, and the International Date Line is subtracted by one day from west to east.

116e local time at 15 o'clock.

1,150e is east of 116e, separated by 34 degrees, 30 degrees for 2 hours, 4 degrees for 16 minutes, a total of 2 hours and 16 minutes.

The 150e local time is 17:16.

2,90e is west of 116e, separated by 26 degrees, for 1 hour and 44 minutes, and it is 13:16.

2. 30W is 20.

1,40W on the west side, separated by 10 degrees, 40 minutes, is 19:20.

2,70W on the west side, 40 degrees apart, 2 hours 40 minutes, 17:20 minutes.

III 120e 18 o'clock.

1,10W, 130 degrees difference, 8 hours and 40 minutes, local time is 20 minutes.

2,170W, which involves the International Date Line, is actually less than 180 degrees, and 170W is on the east side of 120E, 70 degrees apart.

It is 4 hours and 40 minutes, and the preliminary calculation is 22:40, but it takes one day to pass through the international date change line. Actually, 170W local time is 22:40.

1 Summer solstice: The sun shines directly on the Tropic of Capricorn, or the polar day occurs in the Arctic Circle3 c d At the point on this line, the earth is about to enter the night4 a>d>c>b

5 d 18 o'clock.

The horizontal pressure gradient force is the driving force for the formation of the wind, which is always perpendicular to the isobar, from high pressure to low pressure, and the wind near the ground is also affected by the geostrophic deflection force and friction force, and finally the wind direction is obliquely crossed with the isobar, and the geostrophic deflection force in the northern hemisphere is deviated to the right.

Therefore, the d arrow is correct.

It's been a long time since I've studied geography, but I remember that this question is very basic, and many things can be turned directly to the book. But if you're going to study science, just throw geography away now.
