Sunshine in each solar term

(1) The sun rays are perpendicular to the termination line, and the sun shines from the right side, and the left part is the night hemisphere. Just draw it with diagonal lines.

(2) The Arctic Circle and its northern region are extremely bright, and the sun shines directly on the Tropic of Cancer around June 22nd, which is the summer solstice in the northern hemisphere.

(3) The linear velocity of the earth's rotation decreases from equator to poles, and the maximum value is at point D; Point a is located in the arctic circle, which is extremely daytime; From summer to the sun, the height of the sun decreases from the tropic of cancer to the north and south sides at noon, reaching the maximum in BC; E is located in the southern hemisphere, affected by the geostrophic bias, horizontally moving objects deflect to the left, and the sediment deposition on the right bank of the river is serious.

(4) During the summer solstice, the noon sun height decreases from the tropic of cancer to the north and south sides, and the order of noon sun height in the five places is b = c > d > a > e. 。

(5)D is located at the intersection of the morning line and the equator at 6 o'clock local time; Point A is located in the Arctic Circle, with a day length of 24 hours; The local time in B is later than that in the west of A. 。

(6)D is located between the Tropic of Cancer and belongs to the tropics. The sun has two direct opportunities a year.

(7) From June 22nd to September 23rd, the direct point of the sun has been moving southward; The days are getting shorter and shorter and the nights are getting longer and longer in all parts of the northern hemisphere; The polar day range in the Arctic Circle is gradually shrinking; The revolution speed of the earth is slow first and then fast.

So the answer is:

( 1)

(2) Summer solstice; 65438+February 22nd.

(3)D； a； BC; E.

(4)B=C>D>A>E。

(5)D； a； Be late; Sunrise.

(6) tropical; There is direct sunlight twice a year.

(7) alternating current.
