Who proposed the idea of Pangaea?

Back

Alfred Wegener proposed the idea of Pangaea.

What is the theory that explains the movement of continents on Earth's surface?

Back

The theory of continental drift explains the movement of continents on Earth's surface.

Front

Where is the oldest ocean floor located in relation to the mid-ocean ridge?

Back

The oldest ocean floor is located farthest from the mid-ocean ridge.

Front

What is a Deep-ocean Trench?

Back

A Deep-ocean Trench is a valley in the ocean created when one lithosphere plate subducts under another.

Front

What was Pangaea?

Back

Pangaea was an ancient supercontinent made up of the landmasses we know as our present-day continents.

Front

What geological process is responsible for the formation of mountains?

Back

The geological process responsible for the formation of mountains is called orogeny, which involves the collision and convergence of tectonic plates.

Front

What are tectonic plates?

Back

Tectonic plates are large, rigid pieces of the Earth's lithosphere that move and interact at their boundaries.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle.

Front

What is the significance of the mid-ocean ridge?

Back

The mid-ocean ridge is significant because it is a divergent boundary where new oceanic crust is formed as tectonic plates pull apart.

Front

What evidence supports the theory of continental drift?

Back

Evidence supporting the theory of continental drift includes the fit of continental coastlines, fossil distribution, and geological similarities across continents.
