What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other.

Why were Mesosaurus fossils found on separate continents?

Back

Mesosaurus fossils were found on separate continents because there was a divergent plate boundary that pushed the land apart.

How fast do the plates of Earth's outer layer move?

Back

The plates of Earth's outer layer move very slowly, at a rate of about 1 cm per year.

What is the rate of movement of Earth's plates?

Back

Earth's plates move at a rate too slow to be seen by humans, approximately 1 cm per year.

Front

What is the significance of plate tectonics in geology?

Back

Plate tectonics explains the movement of Earth's plates and is fundamental to understanding geological processes such as earthquakes, volcanic activity, and continental drift.

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are divergent, convergent, and transform boundaries.

Front

What occurs at a convergent boundary?

Back

At a convergent boundary, two tectonic plates move towards each other, which can result in one plate being forced beneath another, leading to subduction.

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally.

Front

What geological features are commonly associated with divergent boundaries?

Back

Divergent boundaries are commonly associated with mid-ocean ridges, rift valleys, and volcanic activity.
