6th Grade Plate Tectonics Flashcard

Front

What is a Convergent Boundary?

Back

A type of plate boundary where two tectonic plates move towards each other, often causing one plate to be forced below the other.

Front

What is the Inner Core?

Back

The innermost layer of the Earth, composed entirely of solid iron and nickel.

Front

What causes Earth's tectonic plates to move?

Back

Convection currents in the mantle, which are caused by the heat from the Earth's core.

Front

What is the theory of Plate Tectonics?

Back

The scientific theory that explains how Earth's continents were once part of a supercontinent called Pangea and have drifted apart over time.

Front

What is a Divergent Boundary?

Back

A type of plate boundary where two tectonic plates move away from each other, often creating new crust as magma rises to the surface.

Front

What is a Transform Boundary?

Back

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

Front

What is the Outer Core?

Back

The layer of the Earth located beneath the mantle and above the inner core, composed of liquid iron and nickel.

Front

What is the Crust?

Back

The outermost layer of the Earth, which is solid and relatively thin compared to the other layers.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

Front

What is subduction?

Back

The process by which one tectonic plate is forced under another plate, often leading to volcanic activity.
