The shaded part in Figure 2 represents night, and the horizontal arrow represents sunlight. Look at the picture and answer the following questions (1). At this time, the solar terms in the northern hemisphere are _ _ _ _ _. (2 (1) As can be seen from the figure, the terminator line is tangent to the polar circle, the south of the Antarctic circle is the polar day, and the north of the Arctic circle is the polar night, that is, the winter solstice.

(2) As can be seen from the picture, ③ on the equator, the length of day and night is equal throughout the year, and ① on the Arctic Circle, it is in the extreme night. As the direct point of the sun moves northward, the days in the southern hemisphere become shorter and the days in the northern hemisphere become longer. The length of the day has been shortened.

(3) The linear velocity of the earth's rotation decreases with the increase of latitude. The speed on the equator is the highest, and the pole is zero. It is on the equator. ② Located between the Tropic of Cancer and the Arctic Circle, it belongs to the north temperate zone. ③ It is closest to the Tropic of Cancer, and the height of the sun is the highest at noon.

(4) According to the rotation direction of the earth, it is a dark line from day to night.

(5) At this time, it is the winter solstice, and the global midday sun height distribution law is decreasing from the tropic of Capricorn to the north and south sides.

Fuyang is located in the northern hemisphere with short days and long nights, with the shortest days and the longest nights in a year.

So the answer is:

(1) winter solstice (2) ③; ①; ? ④(3)③; ②; ③

(4) faint

(5) decreasing from the tropic of Capricorn to the north and south sides.

(6) Fuyang has short days and long nights, with the shortest days and the longest nights in a year.
