Find a friend who is good at geography.

Geography is actually partial to science, but it is not difficult for liberal arts students to learn well. I am a liberal arts student, and geography is my best subject. The way for me to learn effectively is very simple, that is, I can't draw a map of the world with my eyes closed. I need to know where the important longitude and latitude lines pass, and I need to know the climate and topography of each place, but I should pay attention to the principles. Geography in senior one is the most difficult to learn. Let me give you some information.

Special topics on earth movement and sunshine map

I. Knowledge structure:

Second, the test sites are sorted out

(1) Rotating motion:

1, direction, period, speed:

(1) direction: three directions (the north pole looks down at the earth, counterclockwise from west to east; Looking down at the earth at the South Pole, clockwise from west to east; Side view of the earth, from west to east around the earth axis. )

(2) Period: Two periods (sidereal day and Solar Day).

Expand thinking: demonstrate the relationship between sidereal day and Sun Day in other three situations with a disc.

A. When the rotation direction is from east to west and the revolution direction is from west to east: sidereal day >; Solar Day (23 hours, 52 minutes and 8 seconds)

B. When the rotation direction is from west to east and the revolution direction is from east to west: sidereal day >; solar day

C. When the rotation direction is from east to west and the revolution direction is from east to west: sidereal day.
