Continental Drift Theory

Front

What is the Continental Drift Theory?

Back

The Continental Drift Theory is the idea that continents were once part of a single landmass called Pangaea, which broke apart and drifted to their current locations.

What happens to temperature, pressure, and density as you move from the crust to the inner core?

Back

All three increase.

Front

Which two continents are most notable for matching coastlines according to Wegener's idea?

Back

South America and Africa.

Front

What are tectonic plates?

Back

Tectonic plates are large pieces of the Earth's crust that move and interact with each other due to convection currents in the mantle.

Front

What is the significance of the fossil Glossopteris in the context of Continental Drift?

Back

Glossopteris is a fossil found on multiple continents, supporting the idea that these continents were once connected.

Front

What role do convection currents play in the movement of tectonic plates?

Back

Convection currents in the mantle cause the movement of tectonic plates.

Front

What is Pangaea?

Back

Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, before breaking apart into the continents we know today.

Front

True or False: The Theory of Continental Drift states that continents drifted away from each other after Pangaea broke apart.

Back

True.

Front

What is the main evidence supporting the Continental Drift Theory?

Back

The matching coastlines of continents, similar fossils found on different continents, and geological similarities.

Front

What is the difference between the crust and the mantle?

Back

The crust is the outermost layer of the Earth, while the mantle is the layer beneath the crust, composed of semi-solid rock.
