Look at the figure below and complete (1)-(3). (Note: the angle of α in the figure is 23 26') Subtle 1: The solar term shown in the figure is () A. Vernal equinox.

Question 1:D?

Question 2

Look at the figure below and complete (1)-(3). (Note: the angle of α in the figure is 23 26') Subtle 1: The solar term shown in the figure is () A. Vernal equinox.

Question 1:D?

Question 2:C

Question 3: A.

Question 1: According to the Northern Lights in the picture, the Northern Lights point to the North Pole. It can be seen from the angle between the solar rays and the terminator line and the 0 meridian that there is an extreme nighttime phenomenon in the Arctic Circle at this time, which is the winter solstice.

Question 2: the time period given by the stem is from winter solstice to vernal equinox; 1 starts, the earth revolves around perihelion, and then the revolution speed of the earth will slow down; The time when the North Indian Ocean current flows clockwise is summer in the northern hemisphere. The main stream of Songhua River should be late in the spring flood season.

Question 3: As can be seen from the figure, the longitude of the 0 meridian passes through the intersection of the morning line and the equator, and it can be known that the local time of the 0 meridian is 6 o'clock, while the 90 E is 12 minute, the day length of a land is 10 hour, and the sunrise time is 7 o'clock. After calculation, its longitude is15 e.
