Pangaea and Plate Tectonics

Front

What is Pangaea?

Back

Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all the continents were joined together as one landmass.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes and volcanic eruptions.

Front

What type of tectonic boundary occurs when two plates are pushing apart?

Back

Divergent boundary.

Front

What is the difference between continental crust and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

Front

Where is the mantle located?

Back

The mantle is located between the Earth's crust and the core.

Front

What evidence did Wegener find to support his theory of continental drift?

Back

Wegener found fossils of the same species on different continents that were separated by oceans.

Front

What type of boundary is associated with earthquakes?

Back

Transform boundary.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates push against each other, often causing one plate to be forced beneath the other.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper part of the mantle.
