Unit Test #9: Plate Tectonics

Front

What is a Divergent Boundary?

Back

A type of plate boundary where two tectonic plates move away from each other, leading to the formation of new crust, such as at the Mid-Atlantic Ridge.

Front

What geological feature is formed at a Divergent Boundary?

Back

New rocks are formed as magma rises to the surface and solidifies.

Front

What is Plate Tectonics?

Back

The scientific theory that describes the large-scale movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What happens at a Transform Boundary?

Back

Two tectonic plates slide past each other, causing earthquakes along faults, such as the San Andreas Fault.

Front

What is a Convergent Boundary?

Back

A type of plate boundary where two tectonic plates move towards each other, often leading to one plate being forced below another (subduction).

Front

What is Subduction?

Back

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

Front

What is the San Andreas Fault?

Back

A transform boundary located in California where the Pacific Plate and North American Plate slide past each other.

Front

What role do volcanic eruptions play in plate tectonics?

Back

Volcanic eruptions can occur at divergent and convergent boundaries, contributing to the formation of new land and altering geological features.

Front

What is the significance of the Mid-Atlantic Ridge?

Back

It is a divergent boundary that is the longest mountain range in the world, formed by the separation of tectonic plates.

Front

What is the effect of plate tectonics on oceanic crust?

Back

Plate tectonics can lead to the creation and destruction of oceanic crust, affecting the geological composition of the oceans.
