Season

Direct Sunlight 直接阳光 When the light from the sun hits the earth in a straight line.

Indirect Sunlight 间接阳光 When the light from the sun hits earth at the angle.

Equator 赤道 Separetes earth in 1/2.

Hemisphere 半球 1/2 of earth.

Tilt 斜 Not straight.

Polaris 南极星 The north star, earth's axis point to this star.

Earth revolution  地球公转 Earth around the sun.

Orbit 轨道 Path on object takes around another object.

Ellipse 椭圆 The shape of Earth's oval

Axis 轴 imaginary line through middle of earth.





Summary:
Earth have 4 season. Spring,Fall,Winter,Summer.When the direct sunlight to the earth is summer. When the indirect sunlight to the earth is winter.The Equator are separate earth in 1/2. One is north hemisphere the other is south hemisphere. when north hemisphere is summer so the south hemisphere will be winter.The earth's axis always point to polaris. The season alway moving to count clock wise.tilt and earth revolution is main cause of the season. The earth's tile is 23.5 degree. and the earth revolution length is one year.At the summer time the earth axis point to the sun.At the winter time the earth axis point away to the sun.The earth orbit the sun. and the shape is ellipse.So sometime the earth close to the sun.

Crical Thinking Question: Hw is earth affected by movement(revolution)?
The earth revolution takes about 365days, and rotation on its axis is 24 hours.Earth tilted is 23.5 degrees. The rotation casues day and night.The earth and the revolution of the earth around the sun also causes 4 different seasons. which are Spring, Summer, Fall and Winter.indirect and direct sunlight Which causes Spring and fall equinoxes, Summer and winter solstices.Summer solstices the longest day in North Hemisphere is June 21/22, while winter solstices is shortest day is on Dec 21/22 South Hemisphere.lunar revolution take 28-31 days.Moon have different phases.The earth have 2 type of tide. Neap tide and spring tide.Is cause by the gravity and lunar revolution.
