Read the schematic diagram of the earth's revolution: (1) The period of revolution of the earth is _ _ _ _ _, and the revolution direction is _ _ _ _ _. (2) There are four solar terms in the picture, Anqing area.

(1) The period of revolution of the Earth is one year; The direction of earth rotation is from west to east; (2) When the earth revolves to point A, the sun shines directly on the Tropic of Cancer, which is the summer solstice in the northern hemisphere. At this time, the days in the northern hemisphere are long and the nights are short. In the annual variation of world temperature, the monthly average maximum temperature appears in 65438+ 10 month in the southern hemisphere, and Antarctica is located in the southern hemisphere, so the maximum temperature generally appears in 65438+ 10 month. Therefore, the highest temperature in Antarctica is Celsius (winter solstice).

So the answer is: (1) one year; From west to east; ② One (summer solstice); C (winter solstice).
