Ch. 17 Plate tectonics

Front

What is a Convergent Boundary?

Back

A type of plate boundary where two tectonic plates move towards each other, often resulting in one plate being forced below the other.

Front

What geologic process formed the Himalayas?

Back

The Himalayas were formed by the convergence of two continental plates.

Front

What type of convergent boundary are the Himalayan mountains located on?

Back

Continental/Continental convergent boundary.

Front

What mechanism moves continents?

Back

Convection in the Asthenosphere.

Front

Where are the youngest rocks on the seafloor found?

Back

Closest to a mid-ocean ridge.

Front

What is a Divergent Boundary?

Back

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

Front

What is a Transform Boundary?

Back

A type of plate boundary where two tectonic plates slide past one another, causing earthquakes.

Front

What is subduction?

Back

The process by which one tectonic plate moves under another plate and sinks into the mantle.

Front

What is a mid-ocean ridge?

Back

An underwater mountain range formed by plate tectonics, where new oceanic crust is created.

Front

What is the Asthenosphere?

Back

A semi-fluid layer of the Earth's mantle that allows tectonic plates to move.
