Geologic Processes-2.2

Front

What is the role of heat from the mantle in the formation of ocean basins?

Back

Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.

Front

Why are earthquakes common in California?

Back

The two plates form a transform boundary because earthquakes are caused by plates sliding past each other.

Front

What type of plate movement results in a volcano forming at a subduction zone?

Back

When an oceanic and a continental plate collide.

Front

Which layer of the Earth is thin, rocky, and has the lowest density?

Back

Crust.

Front

What happens when two tectonic plates push against each other over time?

Back

The plates will slowly converge causing a mountain to form.

Front

What is a tectonic plate?

Back

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

Front

What is subduction?

Back

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

Front

What is a transform boundary?

Back

A transform boundary is a type of fault where two tectonic plates slide past each other horizontally.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.

Front

What geological feature is formed at a divergent boundary?

Back

At a divergent boundary, new oceanic crust is formed, creating mid-ocean ridges.
