8.9AB Plate Tectonics

Front

What are fault lines?

Back

Fault lines are fractures in the Earth's crust where blocks of land have moved past each other, often resulting in earthquakes.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other, leading to mountain formation or volcanic activity.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, leading to the formation of new crust, such as mid-ocean ridges.

Front

What geological feature is formed at a transform boundary?

Back

Faults are the primary geological features formed at transform boundaries.

Front

What is the primary cause of earthquakes?

Back

Earthquakes are primarily caused by the movement of tectonic plates along fault lines.

Front

What is the significance of the Himalayan mountains in plate tectonics?

Back

The Himalayan mountains were formed by the collision of the Indian and Eurasian tectonic plates, illustrating the effects of convergent boundaries.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart, allowing magma to rise and create new crust.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity.

Front

What is a ridge?

Back

A ridge is a long, narrow elevation of land, often formed at divergent boundaries where new crust is created.
