Back

Continental Drift

Front

What are three pieces of evidence for continental drift?

Back

1. The presence of similar fossils on different continents (plant and animal fossils). 2. The fit of the coastlines of South America and Africa, like puzzle pieces. 3. Similar rock formations found on different continents, like mountain ranges

Front

Fill in the blank: ___________________ is the theory that explains the movement of Earth's plates.

Back

Plate Tectonics

Front

What are two pieces of evidence that was used as proof for plate tectonics?

Back

1. Structure of Earth's interior that causes convection in the mantle which creates plate movement. 2. The mid-ocean ridge and Marie Tharp's maps as proof.
