Practice Continental Drift, Seafloor Spreading Plate T

Front

What is Continental Drift?

Back

The theory that continents have moved over geological time and were once joined together in a single landmass.

Front

What is Seafloor Spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What is a tectonic plate?

Back

A large, rigid piece of the Earth's lithosphere that moves and interacts with other plates.

Front

What are the three types of plate boundaries?

Back

Divergent, convergent, and transform boundaries.

Front

What is a tsunami?

Back

A series of ocean waves caused by large-scale disturbances, such as earthquakes, under the sea.

Front

What is Pangaea?

Back

A supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all continents were joined.

Front

What happens at divergent boundaries?

Back

Tectonic plates move apart, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often causing one plate to be forced beneath another.

Front

What is a transform boundary?

Back

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

Front

What is the Ring of Fire?

Back

A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
