Plate Tectonics and Earth Layers

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often resulting in the formation of mountains or subduction zones.

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountains are commonly formed at convergent boundaries due to the collision of tectonic plates.

Front

What is an ocean ridge?

Back

An ocean ridge is a continuous mountain range formed by plate tectonics, typically found at divergent boundaries where tectonic plates are moving apart.

Front

What occurs at transform boundaries?

Back

Transform boundaries are characterized by tectonic plates sliding past each other, often resulting in earthquakes.

Front

What causes the movement of tectonic plates?

Back

The movement of tectonic plates is primarily caused by convection currents in the Asthenosphere.

Front

What is convection in the context of plate tectonics?

Back

Convection is the process of heat transfer in fluids, which in the Earth's mantle causes the movement of tectonic plates.

Front

What is subduction?

Back

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

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once part of a single landmass.

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the Earth's mantle that lies beneath the lithosphere and allows tectonic plates to move.

Front

What is the lithosphere?

Back

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