Front

Who proposed the theory of sea-floor spreading?

Back

Hess

Front

What direction does a tectonic plate move over a hot spot?

Back

In the direction of the oldest volcano.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is a continuous mountain range that runs through the ocean, formed by tectonic plates moving apart.

Front

What does the age of the Hawaiian Islands indicate about their formation?

Back

Hawaii is the youngest island because it is currently on top of the hotspot.

Front

Why was Wegener's theory of Continental Drift initially rejected?

Back

He couldn't explain the FORCE that caused the continents to move.

Front

What is the main driving force behind plate tectonics?

Back

Convection currents in the Earth's mantle.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive slab of solid rock that makes up the Earth's lithosphere.

Front

What is the significance of the hotspot in the formation of islands?

Back

A hotspot is a location where magma from deep within the mantle rises to the surface, creating volcanic islands.

Front

What evidence supports the theory of plate tectonics?

Back

Fossil distribution, geological formations, and the fit of continental coastlines.

Front

What happens at a convergent plate boundary?

Back

Two tectonic plates collide, which can cause earthquakes and volcanic activity.
