Plate Tectonics Test Review

Front

What are the layers of the Earth in order from outside to inside?

Back

Crust, Lithosphere, Asthenosphere, Mantle, Outer Core, Inner Core.

Front

What can be inferred if fossils of a tropical plant are found in an ice-covered region?

Back

This area once had a much warmer climate allowing the tropical plants to grow.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often creating subduction zones and volcanoes.

Front

What is a midocean ridge?

Back

A midocean ridge is an underwater mountain range formed by plate tectonics, where new seafloor is created.

Front

What is a subduction zone?

Back

A subduction zone is an area where one tectonic plate is being forced under another, leading to volcanic activity.

Front

How do midocean ridges and trenches work together?

Back

New seafloor is made at midocean ridges, while old seafloor is subducted at trenches, keeping Earth the same size.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the upper mantle that allows tectonic plates to move.

Front

What happens at a transform boundary?

Back

At a transform boundary, two tectonic plates slide past each other, which can cause earthquakes.

Front

What evidence supports the theory of plate tectonics?

Back

Fossil distribution, geological formations, and the fit of continental coastlines support the theory of plate tectonics.
