Draw the direction of the earth's revolution with an arrow at the appropriate position. How long does it take for the earth to make a circle?

Look at the map and it shows (1) that the revolution direction of the earth is from west to east. It takes a year for the earth to go around once. (3) When the earth is in position B, the latitude of direct sunlight is tropic of Capricorn. At this time, the solar term is the winter solstice. When the earth is at position C, the latitude of direct sunlight is equator, and the solar term is vernal equinox. (4) When there is an extreme day in the Arctic, the earth is located at point D, and the solar term is from summer to sun, and the date is around June 22nd. (5) Wuyishan is the dividing line between Jiangxi Province and Fujian Province. When the earth is located at the vernal equinox at point D or the autumnal equinox at point A, the world is equal to day and night, so Wuyi Mountain is also day and night.

So the answer is:

(1) as shown in the figure:

(2) one year;

(3) Tropic of Capricorn; Solstice of winter; Equator;

(4)D；

(5)D； A.
