8.9AB Plate Tectonics

Front

What is Plate Tectonics?

Back

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

Front

What are tectonic plates?

Back

Large, rigid pieces of the Earth's lithosphere that move and interact at their boundaries.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates push toward each other, often forming mountains or causing subduction.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other, often creating new oceanic crust.

Front

What is a transform boundary?

Back

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

Front

What geological feature is commonly formed at convergent boundaries?

Back

Mountain ranges, such as the Himalayas.

Front

What geological feature is commonly formed at divergent boundaries?

Back

Mid-ocean ridges, such as the Mid-Atlantic Ridge.

Front

What is the San Andreas Fault?

Back

A transform fault located in California, known for its significant seismic activity.

Front

What is subduction?

Back

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

Front

What is a mid-ocean ridge?

Back

An underwater mountain range formed by plate tectonics at divergent boundaries.
