Layers of the Earth and Plate Tectonics

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often resulting in one plate being forced beneath the other, leading to subduction.

Front

What is the theory of Continental Drift?

Back

The theory of Continental Drift suggests that continents were once part of a single landmass and have since drifted apart over geological time.

Front

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

Back

As you go deeper into the Earth, both temperature and pressure increase.

Front

What geological event is commonly associated with transform boundaries?

Back

Earthquakes are commonly associated with transform boundaries, where two plates slide past each other.

Front

What type of boundary is characterized by subduction?

Back

A convergent boundary is characterized by subduction, where one tectonic plate is pushed under another.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What is the significance of the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle, and is involved in tectonic plate movements.

Front

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.

Front

What is the role of mantle convection in plate tectonics?

Back

Mantle convection is the process by which heat from the Earth's interior causes the mantle to flow, driving the movement of tectonic plates.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally, leading to friction and earthquakes.
