Plate Tectonics and Earth Layers

Front

What is the crust?

Back

The outermost layer of the Earth.

Front

What type of boundary is formed where two sections of Earth’s crust are colliding?

Back

Convergent boundary.

Front

What is the inner core?

Back

The innermost layer of solid metal in the Earth.

Front

What is the theory that continents were once part of a single landmass?

Back

Continental Drift.

Front

What geological feature is commonly found at convergent boundaries?

Back

Mountains.

Front

What are tectonic plates?

Back

Large sections of the Earth's crust that move and interact with each other.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What occurs at divergent boundaries?

Back

Tectonic plates move apart, often creating new crust.

Front

What is subduction?

Back

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