plate tectonics

An introduction to the theory of plate tectonics which explains the shifting of continents, the formation of mountains and oceans, and the causes of earthquakes and volcanoes.

"Examines the 1980 eruption of Mount St. Helens volcano, including the cause of the eruption, its impact on surrounding environments, and stories from survivors"--Provided by publisher.

Presents information on earthquakes and their effect on planet Earth, giving specific examples from around the world.

Looks beneath the ocean's surface at the shifting of tectonic plates, the relationship between ocean and climate, and the complex paths of currents that thread the seas.

Discusses how continents move, how mountains are formed, volcanoes, and what occurs during an earthquake.

A graphic presentation of the causes and results of earthquakes, including research methods scientists employ as they investigate the origin, nature and control of this force.

Describes how tectonics works, the role of seafloor spreading, how mountains and volcanoes are formed, and what happens when continents collide.

Explains what tectonics plate are, how they shift to create land formations, and how volcanoes and earthquakes are caused by shifting plates.

Explains what happens to the earth before and during a volcanic eruption, and describes several historic eruptions, including Mount Saint Helens in 1980.
