Types of Plate Boundaries

Flashcards covering the three main types of tectonic plate boundaries, their movements, crustal impacts, features, and real-world examples based on the lecture transcript.

What is a plate boundary?

The edge where two tectonic plates meet.

What geological features and events are shaped by the movement of tectonic plates?

Mountains, volcanoes, earthquakes, and ocean basins.

What is another name for a divergent boundary, and how do the plates move?

It is also known as a constructive boundary, and the plates move apart.

How is new crust formed at a divergent boundary?

Magma rises from below to fill the gap created as the plates move away from each other.

What common features are associated with a divergent boundary?

Mid-ocean ridges, rift valleys, volcanic activity, and earthquakes.

What example of a divergent boundary is given in the transcript?

Mid-Atlantic Ridge.

What is another name for a convergent boundary, and how do the plates move?

It is also known as a destructive boundary, and the plates move together.

What two processes can occur when plates interact at a convergent boundary?

Subduction (where one plate sinks beneath the other) or collision (where two continental plates collide and crumble).

What common features are formed at convergent boundaries?

Deep ocean trenches, volcanoes, mountain ranges, and strong earthquakes.

What examples of convergent boundaries are cited in the transcript?

Andes Mountains (Oceanic-Continental) and Himalayas (Continental-Continental).

What is another name for a transform boundary, and how do the plates move?

It is also known as a conservative boundary, where plates slide horizontally past each other along fault lines.

Is crust created or destroyed at a transform boundary?

No crust is created or destroyed.

What common features are found at a transform boundary?

Fault lines, frequent earthquakes, and no volcanoes.

What specific example of a transform boundary is named in the transcript?

San Andreas Fault, California, USA.
