Summary of high school geography knowledge points (detailed)
The first year of the Geography Exam of the Senior High School
The relationship between the rotation and revolution of the earth:
(1) Yellow-Equatorial Intersection: The intersection angle of the equator plane and the ecliptic plane. Currently 23º26 '(2) The movement of the direct solar point between the North and South Tropics
2: Geographical Significance of Earth Rotation
(1) Day and night change (2) Local time (3) Objects moving horizontally along the ground surface are shifted, rightward in the northern hemisphere, leftward in the southern hemisphere. 3: Geographical significance of the Earth's revolution
(1) Changes in the length of day and night and the height of the sun at noon ① Changes in the length of day and night
Northern Hemisphere: In the summer half of the year, the day is short, and the day is longer and longer toward the north. ①The direct sun point is in that hemisphere, and the polar day phenomenon occurs north of the Arctic Circle. The hemisphere has long day. The shorter the day is, the day and night are evenly divided. ③ The polar night phenomenon appears to the north of the global Arctic Circle on the spring and autumn equinoxes. The day and night are equally divided in the southern hemisphere: contrary to the northern hemisphere.
Spring and Autumn Equinox Days: Decrease from the equator to the north-south direction. From the direct point of the sun to the north and south.
To the north of 23º26′N, the maximum value is reached on the summer solstice.
South of 23º26 ′S reaches the maximum value on the winter solstice
