Topic 5 Test Review: Plate Tectonics

Front

What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is a mid-ocean ridge?

Back

An underwater mountain range formed by plate tectonics at divergent boundaries where tectonic plates are moving apart.

Front

What happens at a convergent boundary?

Back

Two tectonic plates move towards each other, which can result in the formation of mountains, earthquakes, or volcanic activity.

Front

What is a transform boundary?

Back

A type of plate boundary where two tectonic plates slide past each other, often causing earthquakes.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and gradually moves away from the ridge.

Front

What evidence supports the Plate Tectonics Theory?

Back

Similar rock and fossil evidence found on different continents, and the fit of continents like a puzzle, support the theory.

Front

What are convection currents?

Back

The movement of fluid caused by differences in temperature and density, which drives the movement of tectonic plates.

Front

What is a divergent boundary?

Back

A plate boundary where two tectonic plates move apart from each other, often resulting in seafloor spreading.

Front

What geological features are formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs can be formed at convergent boundaries.

Front

What is the asthenosphere?

Back

The semi-fluid layer of the Earth's mantle beneath the lithosphere, which allows tectonic plates to move.
