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 ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

Hand each student a plate boundary map and a slip of paper with ... Use Graphic 2 to discuss convergent, divergent, and transform boundaries. Explain why each of these boundaries has the ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

At divergent boundaries ... Wannamaker and colleagues use electrical resistivity data to investigate a plate boundary in New Zealand where a subduction zone beneath the North Island is lengthening ...

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But ...

According to plate tectonics theory, Earth's outer shell is divided into multiple plates that slowly glide over the mantle. This slowly changes Earth's surface over time by merging, or separating ...

Underwater, though, submarine mountains usually form as two plates drift apart at a so-called divergent boundary and magma spews out. But far away from these plate boundaries, at the center of ...

Where plates meet, their relative motion determines the type of boundary; convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur ...

This is called a constructive or divergent plate boundary. These are usually found under oceans. As the plate moves apart, magma rises to the surface and cools, forming shallow-sided volcanoes.
