On the schematic diagram of the earth's revolution, A, B, C and D respectively represent the time period between two half-years and four solar terms. Fill in the blanks: (1) Draw the earth at n in the picture. (1) The rotation of the earth is in the same direction as the revolution of the earth, both from west to east.

(2) From the schematic diagram of the earth's revolution, it can be seen that when the earth is in the m position, the latitude of direct sunlight is the Tropic of Capricorn, that is, the winter solstice in the northern hemisphere, and the date is around 65438+February 22.

The positions of two-thirds to four solar terms are shown in the figure. According to the figure, we can see that:

(3) The period from the vernal equinox (northern hemisphere) to the summer solstice (northern hemisphere) is represented by the letter A in the figure.

(4) From the vernal equinox to the summer solstice, the direct point of the sun moves from the equator to the Tropic of Cancer (moving northward); B From summer solstice to autumnal equinox, the tropic of cancer moves to the equator (southward); C from the autumnal equinox to the winter solstice, the direct point of the sun moves from the equator to the tropic of Capricorn (south); From the winter solstice to the vernal equinox, the tropic of Capricorn moves to the equator (north).

(5) The periods of short days and long nights in the northern hemisphere are C and D near the winter solstice.

(6) When the direct point of the sun moves southward, the days in the northern hemisphere become shorter day by day, with periods of B and C. 。

So the answer is: (1); (2) Solstice in winter; 65438+February 22nd; (3) a; (4) a; d； (5)C； d； (6)B； C.
