Authoritative PPT Summary
"Earth's Revolution" PPT
Part One: Thoughts on Earth’s Revolution
When the earth rotates, the side facing the sun is daytime
The spatial orientation of the Earth's axis remains unchanged as the Earth revolves
If the earth's axis were not tilted, the sun would always shine directly at the equator
Changes in the sun's direct irradiation point at different positions of revolution
Thinking: Can all places on the earth be exposed to direct sunlight?
Tropic of Cancer: The northernmost latitude that can be reached by direct sunlight.
Tropic of Capricorn: The southernmost latitude that can be reached by direct sunlight.
Think about it: Which season has the longest days? Which season has the shortest days?
Analysis: What is the relationship between the length of the day and the hemisphere where the direct sun shines?
Summary: In the hemisphere where the direct sun shines, the day is longer than the night.
The Earth's Revolution PPT, Part 2: The Geographical Significance of the Earth's Revolution
content
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
(2) Changes in the height of the sun at noon
The division of four seasons and five zones
(1) Division of four seasons
(2) Division of five zones
(1) Changes in the length of day and night
1. Seasonal changes in day and night length:
(1) Vernal Equinox ~ Autumnal Equinox (summer half of the year):
The days are long and the nights are short. The higher the latitude, the longer the days. Summer Solstice: The longest day and shortest night in the Northern Hemisphere. Polar day occurs north of the Arctic Circle.
(2) Autumnal equinox ~ spring equinox of the following year (winter half of the year):
The days are short and the nights are long. The higher the latitude, the shorter the days. Winter Solstice: The shortest day and the longest night, polar night occurs north of the Arctic Circle
(3) Vernal and autumnal equinoxes: global daytime
Nights are of equal length, all 12 hours.
(2) Changes in the height of the sun at noon
At the same time, the height of the sun at noon decreases from the direct sun point to the north and south sides.
On the summer solstice, the sun shines directly on the Tropic of Cancer, and at all latitudes north of the Tropic of Cancer, the height of the sun reaches its maximum value in the year at noon; in the southern hemisphere, it reaches its minimum value in the year.
On the winter solstice, the sun shines directly on the Tropic of Capricorn, and at all latitudes south of the Tropic of Capricorn, the height of the sun at noon reaches its maximum value in the year; in the Northern Hemisphere, it reaches its minimum value in the year.
On the vernal and autumnal equinoxes, the sun shines directly at the equator. The height of the sun at noon decreases from the equator to the poles.
(3) Division of four seasons
1. Divide according to the inter-annual changes in day and night length and the inter-annual changes in the height of the sun at noon.
2. Astronomical seasons:
China: Starting from the beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter
Europe and the United States: starting from the spring equinox, summer solstice, autumnal equinox, and winter solstice
3. Climate four seasons:
In north temperate countries, 3, 4, and 5 are spring; 6, 7, and 8 are summer; 9, 10, and 11 are autumn; and 12, 1, and 2 are winter.
Supplementary information: Ancient Chinese astronomers and working people divided the Earth's orbit around the sun into twenty-four segments, each segment being called a solar term.
