The movement of the plates creates three types of tectonic boundaries ... boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass.

Plate tectonics is a perfect example of this ... One of the key observations was that of sea-floor spreading - the process that creates new crust at the ridges from upwelling magma.

This advanced undergraduate textbook provides a thoroughly modern overview of plate tectonics and is the perfect resource for a capstone geology course. It presents plate tectonics as a multifaceted, ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

In this lesson, students use scientific data to learn how the scientific process works. They learn where the Earth's tectonic plates and their boundaries are, what happens at the boundaries ...

But researchers don't know why or when plate tectonics started, making it hard to determine how essential this process was to the evolution and diversification of life. Some think plate movement ...

The African continent is undergoing a dramatic transformation as tectonic forces carve a path toward the formation of a new ...

The mid-ocean ridges mark the lines along which the Earth is turning itself inside out through the process of plate tectonics. Advances in technology are helping to reveal the intricate details of ...

A significant geological shift is gradually reshaping our planet's surface. Scientists have uncovered evidence of a new ocean ...
