Continental Drift and Plate Tectonics Review

Front

What is Continental Drift?

Back

A theory that explains how continents move over time due to tectonic plate movements.

Front

Who proposed the theory of Continental Drift?

Back

Alfred Wegener.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other.

Front

What geological feature is formed when tectonic plates collide?

Back

Mountains.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is created at mid-ocean ridges as tectonic plates pull apart.

Front

What is the significance of Harry Hess in geology?

Back

He published the theory of seafloor spreading in 1962.

Front

What happens at divergent plate boundaries?

Back

Tectonic plates move apart, leading to the formation of new crust.

Front

What geological activities can occur at plate boundaries?

Back

Earthquakes, volcanoes, and mountain building.

Front

What is the lithosphere?

Back

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

Front

What is a fault line?

Back

A fracture in the Earth's crust where blocks of land have moved past each other.
