Read the north-south movement map of the sun's direct point and answer the following questions: 1: What solar terms will Lanzhou welcome when the sun's direct point moves to position D (

Question 1:D

Question 2: A.

Question 3:C

Question 4:C

Test analysis:

Question 1: The above picture is the regression motion diagram of the direct point of the sun. According to the picture, we can see that A is the vernal equinox, B is the summer solstice, C is the autumn equinox, and D is the winter solstice. Therefore, when the direct point of the sun moves to D, the solar term that Lanzhou will usher in is the winter solstice.

Question 2: When the direct point of the sun moves to position A, it is the vernal equinox, and the sun is directly on the equator, so the noon sun height angle of the direct point is 90, so this question chooses A.

Question 3:A is the vernal equinox (March 2 1), B is the summer solstice (June 22), C is the autumn equinox (September 23), and D is the winter solstice (February 22 13+ 10).

Question 4: When the direct point of the sun is located at position B, that is, when the tropic of Cancer is directly exposed, the days in the northern hemisphere are long and the nights are short. The higher the latitude, the longer the days are, so the days in Lanzhou are long and the nights are short.
