Chemistry - Tectonic Plates and Boundaries

These flashcards cover the concepts related to tectonic plates and their boundaries, including types of boundaries, characteristics, and geological effects.

What are the two main types of boundaries at plate tectonics?

Convergent and divergent boundaries.

What occurs at a convergent boundary?

Two plates move toward each other, causing earthquakes, volcanic activity, and deep ocean trenches.

What type of earthquakes are associated with divergent boundaries?

Shallow earthquakes.

What is created when two tectonic plates move away from each other?

Small ridges and young land.

Which boundary is characterized by plates sliding past each other?

Transform boundary.

What is a key characteristic of the transform boundary?

Frequent but shallow earthquakes with few volcanoes.

What happens to land at a convergent boundary?

The crust crumbles, leading to strong earthquakes and volcanic activity.

What type of landforms are caused by divergent boundaries?

Small ridges and young land.

What kind of earthquakes occur at convergent boundaries?

Deep and strong earthquakes.

Which tectonic boundary is associated with no volcanoes?

Transform boundary.
