  • Topography of the Southwestern US
    Chapter 4: Topography of the topography • the landscape Southwestern US of an area, including the presence or absence of hills and the slopes between high and low areas. Does your region have rolling hills? Mountainous areas? Flat land where you never have to bike up a hill? The answers to these questions can help others understand the basic topography of your region. The term topography is used to describe the shape of the land surface as measured by how elevation— geologic time scale • a height above sea level—varies over large and small areas. Over geologic standard timeline used to time, topography changes as a result of weathering and erosion, as well as describe the age of rocks and fossils, and the events that the type and structure of the underlying bedrock. It is also a story of plate formed them. tectonics, volcanoes, folding, faulting, uplift, and mountain building. The Southwest’s topographic zones are under the influence of the destructive surface processes of weathering and erosion. Weathering includes both the plate tectonics • the process mechanical and chemical processes that break down a rock. There are two by which the plates of the types of weathering: physical and chemical. Physical weathering describes the Earth’s crust move and physical or mechanical breakdown of a rock, during which the rock is broken interact with one another at their boundaries. into smaller pieces but no chemical changes take place. Water, ice, and wind all contribute to physical weathering, sculpting the landscape into characteristic forms determined by the climate. In most areas, water is the primary agent of erosion.
