How Surface Energy Shapes the Land

Show Summary Details


Land surfaces everywhere are nearly always uneven or hilly to some extent, even where there are no mountains; expanses of truly flat land, such as dry lake beds, are always surrounded by higher ground. Land is raised into hills, ridges, mountains, and volcanoes by the earth's internal energy. The raised surfaces are simultaneously worn down by wasting and erosion, which sometimes smoothes the relief and sometimes — as when rivers erode deep valleys, for instance — exaggerates it. The energy of these external agents is the focus of this chapter. It discusses the process of weathering; mass wasting; the energy in rivers; and beach drift.
