Plate Tectonics and Rock Cycle Review (A)

Front

What is an igneous rock?

Back

A type of rock that forms when melted rock cools and hardens.

Front

What is a sedimentary rock?

Back

A type of rock formed by gravity pressing fragments of other rocks and minerals together as they settle on land or under the ocean over a long period of time.

Front

What does the Theory of Plate Tectonics explain?

Back

It explains the slow constant motion of the plates that make up the Earth's crust.

Front

What is sea-floor spreading?

Back

A process that continually adds materials to the ocean floor, creating new oceanic crust.

Front

What is the Rock Cycle?

Back

A continuous process that describes the transformation of rocks from one type to another, including igneous, sedimentary, and metamorphic rocks.

Front

What are tectonic plates?

Back

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

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often forming mountains or causing earthquakes.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move apart, often creating new crust as magma rises to the surface.

Front

What is a transform boundary?

Back

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

Front

What is subduction?

Back

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