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

A textbook on geology, rocks, and rock structures that covers such topics as mountains, volcanoes, erosion and sedimentation, caves and caverns, asteroids and comets, canyons, and rock monuments, and includes photos, a glossary, and a bibliography.

Examines the geologic forces that shape the Earth, and discusses the hazards posed by plate tectonic activity, earthquakes, volcanic eruptions, ground failure and collapse, floods, dust storms, glaciers, and impact cratering.

Discusses the historical periods of ice ages, causes and effects of glacier formations, and glacial deposits.
