What is a convergent boundary?

Back

A convergent boundary is a place where two tectonic plates come together, often causing one plate to be forced beneath the other, leading to geological features like mountains and earthquakes.

What is the least dense compositional layer of the Earth?

Back

The crust is the least dense compositional layer of the Earth, consisting of solid rock and minerals.

Front

What type of plate boundary formed the Himalayas?

Back

The Himalayas were formed by a continent-to-continent convergent boundary, where two continental plates collided.

How do ocean crusts move during sea-floor spreading?

Back

During sea-floor spreading, ocean crusts move by diverging, or pulling apart, from each other.

What type of boundary is the San Andreas Fault?

Back

The San Andreas Fault is a transform boundary, where two tectonic plates slide past each other.

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.

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.

Front

What is the mantle?

Back

The mantle is the thick layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is sea-floor spreading?

Back

Sea-floor spreading is the process by which new oceanic crust is created at mid-ocean ridges as tectonic plates diverge.
