Look at the schematic diagram of the earth's revolution and ask questions (1). Name the solar terms when the earth revolves to four places in the picture. A _ _ _ _ _ B _ _ _ _ _ C _ _ _ _ _ D _ _ _ _ _ (2 When (1) As can be seen from the schematic diagram of the earth's revolution, when the earth is in position A, the sun is directly on the Tropic of Cancer, which is the summer solstice in the northern hemisphere, and the date is around June 22nd. When the earth is in position B, the latitude of direct sunlight is the equator, which is the vernal equinox day in the northern hemisphere, and the date is about March 2 1; When the earth is in position c, the sun shines directly. The date is around 65438+February 22, the earth is in position D, and the latitude of direct sunlight is the equator. At this time, it is the autumn equinox in the northern hemisphere, and the date is around September 23;

(2) It can be seen from the schematic diagram of the earth's revolution that when the earth is in position A, the sun is on the tropic of cancer, which is the solstice of summer in the northern hemisphere, and the date is around June 22nd. At this time, it is extremely dark in the Arctic, China is in summer, and the direction of the earth's revolution is from west to east, with a period of one year.

Therefore, the answer is: (1) summer solstice; Vernal equinox; Solstice of winter; Vernal equinox; (2) A; One year.
