Plate Tectonic Test Review

Front

What is the theory of Plate Tectonics?

Back

The theory that Earth's outer shell is divided into several plates that glide over the mantle, causing geological activity.

Front

What is continental drift?

Back

The gradual movement of continents across the Earth's surface through geological time.

Front

What are convergent boundaries?

Back

Boundaries where two tectonic plates collide, often forming mountains or trenches.

Front

What landform is created at convergent boundaries between oceanic and continental plates?

Back

Ocean trench.

Front

What is an oceanic plate?

Back

A tectonic plate that lies beneath the ocean, typically denser than continental plates.

Front

What is a continental plate?

Back

A tectonic plate that forms the continents, generally less dense than oceanic plates.

Front

What evidence supports the theory of continental drift?

Back

Fossil distribution, matching geological formations, and glacial deposits found in warm regions.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and gradually moves away from the ridge.

Front

What are earthquakes?

Back

Sudden shaking of the ground caused by the movement of tectonic plates.

Front

What is a rift valley?

Back

A lowland region formed by the divergence of tectonic plates.
