and how scientists classify plate boundaries. This curriculum encourages students to observe, describe, and classify scientific data to learn about a scientific process. This activity is designed ...

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 ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through ...

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 ...

Most geologic activity stems from the interplay ... These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass. As the overlying plate ...

Learn how a computer simulation demonstrates that tectonic activity may be less slow and steady than previously thought.

New research suggests melting ice sheets are warming global temperatures which may speed up continental drift, creating ...

When the ground shakes violently, entire cities can crumble within minutes. Homes, hospitals, roads, and lives can vanish ...

The Earth’s crust is divided into large, rigid tectonic plates that move over time, driving earthquakes, volcanic activity ... recent discoveries in plate tectonics is the confirmation of ...

In an article published in Science Advances, a collaborative team led by the Woods Hole Oceanographic Institution (WHOI) ...

Plate tectonics is relatively new, put forth in the last 30 years or so — its forerunner was the now-discarded continental drift theory. The theory states that Earth's outer shell is made up of ...
