Earth Layers/Plate Tectonics

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, leading to the formation of new crust. An example is the Great Rift Valley.

What is the density comparison between oceanic crust and continental crust?

Back

Oceanic crust is denser than continental crust.

Front

How do temperature and pressure change as you go deeper into the Earth?

Back

Both temperature and pressure increase as you move to deeper layers within the Earth.

What is the theory of Continental Drift?

Back

The theory of Continental Drift suggests that continents were once joined together and have since drifted apart over geological time.

What did Harry Hess propose about mid-ocean ridges?

Back

Harry Hess proposed that the valleys of mid-ocean ridges are actual cracks within the Earth's crust where new crust is formed.

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with one another, causing geological activity.

What is the lithosphere?

Back

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

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move towards each other, often resulting in one plate being forced beneath another.
