Why Do We Still Have Mountains ?

Discusses the nature of mountains and the geological concepts dealing with weathering and erosion and with the formation of the earth's crust. Shows that uplift is occurring today at rates which could produce mountains in a geologically short time., Considers the seeming paradox that erosion should long ago havee carried all the land above sea level into the oceans. Explores several of the ways in which mountains are formed and examines the evidence associated with the uplife of the Earth's crust., Pictures the wearing away of mountains and explains how this process is counteracted by forces within the earth which form mountains faster than they can be eroded away. Points out that mountains are formed by volcanic activity and by upward movement of portions of earth's crust. Describes measurements taken during the past forty years which record areas of uplift.
