1. Earth's axial tilt (also known as the obliquity of the ecliptic) is about 23.5 degrees. Due to this axial tilt, the sun shines on different latitudes at different angles throughout the year. This causes the seasons.
2. The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres.
3. Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.
4. Each planet rotates, or spins, on its axis. The rotation of the Earth on its axis causes day and night. ... Because of this direction of rotation, we see the sun rising every day in the east and setting in the west. If a planet spins in a clockwise direction, it is said to have a retrograde rotation.
5. The sun's rays do not strike the Earth's surface as directly at the North Pole; they are less focused. The equator receives the most solar radiation in a year.
