9. What causes daytime and night time on the Earth? What causes the changing of our seasons?
10. The Earth whizzes along spinning in space at 67,000 miles an hour. We can’t feel it spinning. Yet is makes one complete turn every 24 hours.
11. This spinning around like a top is called rotation . As it spins only one side faces the sun. Day begins when our part of the world turns to face the sun.
12. Night falls when our part of the Earth turns away from the sun. The side facing away from the sun has nighttime.
13. This rotation or spinning of Earth causes day and night. The Earth rotates on its axis. The axis is an imaginary line through its center. It rotates once every 24 hours causing day and night . www.enchantedlearning.com/subjects/astronomy/activities/radiobuttonquiz/Earthpz.shtml
