Arêtes: An arête is a sharp, steep ridge that ...
Jun 27, 2019 · The Short Answer: A planet is round because of gravity. A planet's gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.
Depending on the grade level of your class, it might not be long before someone answers that the cause of the pulling on the Earth is gravity! Gravity pulls on the Earth from all directions (see Figure 5) and keeps any part of the Earth from sticking out very far. Just as squeezing the Play-Doh from all directions made the Play-Doh round ...
All the other planets and stars we've ever seen are round, and there's no reason to indicate that the earth should be any different. Number nine. Time zones. Day and night happen at different times at different places on earth. In fact it's always day somewhere and night somewhere else. Number eight. The Coriolis Effect means freely moving ...
