Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

In this lesson, students learn about the different kinds of faults produced by different kinds of plate motions (see Lesson 2) and their relation to earthquakes. This activity is designed for one ...

Most geologic activity stems from the interplay where the plates meet or divide. The movement of the plates ... where plates move into one another; divergent, where plates move apart; and ...

Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ... plates build up tension, then release the tension with a spurt of movement.

Sinking in one place leads to plates moving apart in other places. The movement of the plates and the activity inside the Earth, is called the theory of plate tectonics.

Where the movements of the currents in the mantle separate, like this, plates move apart. This is called a constructive or divergent plate boundary. These are usually found under oceans.
