Pangaea

Back 5

a gigantic supercontinent which the scientist Wegner thought existed over 200 million years ago

Front 6

Tectonic plate

Back 6

plates that float on the earth’s surface and their movement causes earthquakes, volcanoes and the creation of mountains

Ring of Fire

Back 13

Surrounds the Pacific ocean in a line that stretches from the tip of South America to the coast of Asia. This is the area where a large number of earthquakes and volcanic eruptions occur

Front 14

Transpiration

Back 14

The process where water contained in liquid form in plants is converted to vapor and released to the atmosphere.

Front 15

Precipitation

Back 15

water released from clouds in the form of rain, freezing rain, sleet, snow, or hail

Evaporation

Back 17

the process by which water changes from a liquid to a gas or vapor.
