In the lab, I observed how convection moves Earth’s plates. I also saw how plates interact with each other. When plates move apart from each other at divergent boundaries, magma from the mantle reaches Earth’s surface and new crust forms. When plates move toward each other at convergent boundaries, volcanoes, mountains, and trenches form. When the plates rub against each other at transform boundaries, earthquakes may occur. Plate movements may change the shape of Earth’s surface and cause geologic events such as earthquakes.
What first comes to my mind is that one or more rivers feature very prominently in these civilizations: the Nile in the Egyptian and the Tigris and Euphrates in the Babylonian.
