What is Pangea?

Back

Pangea 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 evidence supports the theory of continental drift?

Back

Fossils of the same species found on different continents, similar rock formations on different continents, and the way continents fit together like puzzle pieces.

Front

What is a hot spot in geology?

Back

A hot spot is an area in the mantle where hot rock rises upward, leading to volcanic activity.

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.

Front

What happens at a transform boundary?

Back

At a transform boundary, two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is sea-floor spreading?

Back

Sea-floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What is the theory of plate tectonics?

Back

The theory of plate tectonics explains how the Earth's plates move and interact, leading to geological phenomena like earthquakes, volcanoes, and mountain building.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often causing volcanic activity.

Front

What are convergent boundaries?

Back

Convergent boundaries are areas where two tectonic plates collide, leading to mountain formation, earthquakes, and volcanic activity.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once joined together.
