VALLEYS! By: Samantha Easter- Brown ~ Valleys are one of the most common landforms on the Earth and they are formed through erosion or the gradual wearing down of the land by wind and water. In river valleys for example, the river acts as an erosional agent by grinding down the rock or soil and creating a valley ~A valley is a landform that is lower than the surrounding area

The Shape ~The form of a valley depends upon the rate at which deepening and widening goes on. V- shaped valleys are caused by forces such as erosion and rivers ~V-shaped valley, sometimes called a river valley, is a narrow valley with steeply sloped sides that appear similar to the letter "V" from a cross-section.

How is it Formed? A valley is a hollow or surface depression 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

CharacteristicsCharacteristics Erosion by rivers is a main valley-forming process; other processes, such as movement of the earth's crust and glaciers, also have an important part in some cases Erosion by rivers is a main valley-forming process; other processes, such as movement of the earth's crust and glaciers, also have an important part in some cases The rate at which a river deepens its valley depends on several factors. One factor is how fast the water is going down a channel. The water will generally reach a maximum at the point where the slope is steep.

Where Are Valleys Found? Valleys are mainly in the north part of western Australia

Valley Plants Willamette Valley prairies support a wide range of interesting plants. Because plants are the core of the prairie, prairie preservation and management should start with a fundamental understanding of plants.

SummarySummary A valley is a long, narrow region of low land between ranges of mountains, hills, or other high areas, often having a river or stream running along the bottom. Valleys are most commonly formed through the erosion of land by rivers or glaciers. They also form where large regions of land are lowered because of geological faults!!
