Landforms
2nd Period 3-6-13 Landforms are natural features of the landscape, natural physical features of the earth’s surface, for example, valleys, plateaus, plains, and hills.
A valley is a hollow or surface of the earth bounded by hills or mountains, a natural trough in the earth's surface, that slopes down to a stream, lake or the ocean, formed by water and/or ice erosion. Systems of valleys extend through plains, hills, and mountains. Rivers and streams flowing through valleys drain interior land regions to the ocean. At the bottom of many valleys is fertile soil, which makes excellent farmland. Most valleys on dry land are formed by running water of streams and rivers .The bottom of a valley is called its floor. A plateaus is a large area of fairly level land separated from surrounding land by steep slopes. “Some plateaus of Tibet, lie between mountain ranges.” others are higher then surrounding lands. “Plateaus are widespread, and together with enclosed basins they cover about 45 percent of the earth’s surface.” Also, some other Plateaus like the Deccan of India basaltic and were formed as the result of many lava flows covering hundreds os thousands of square kilometers that built up the land surface. “Plains are broad, nearly level stretches of the land that have no great changes in elevation.” Plains are generally lower than the land around them; they may be found along the cost or inland. Coastal plains generally rise from sea level until they meet higher landforms such as mountains and plateaus. Island plains may be at high altitudes. Plant life on the plains is controlled by the climate. Thick forests usually thrive on plains in humid climates. Hills are elevations of the earth’s surface that have distinct summits, but are lower in elevations than mountains. “Hills also may be forms
