What are valleys write an example?

A valley is a depressed area of land between mountains or hills. When valleys first form between mountains, they often have a deep V shape: for example, a river canyon, a specific type of V-shaped valley formed by the erosion of the land by a river over time.

Why are valleys famous?

Simply put, valleys are stretches of depressed land located between hills or mountains. Oftentimes, they contain a series of rivers or lakes that give life to a diverse collection of flora and fauna. Some valleys are considered to be the most idyllic places in the entire world.

What plants and animals live in Death Valley?

Of course, the park is home to more “traditional” wildlife, such as coyotes, bobcats, desert bighorn sheep, nine bat species, gophers, kangaroo rats, cottontails (mountain and desert), fox, badgers, ringtails, and even some mountain lions.

How do you describe valleys?

Valleys are depressed areas of land–scoured and washed out by the conspiring forces of gravity, water, and ice. Some hang; others are hollow. They all take the form of a “U” or “V.”

What are the two types of river valleys?

There are three main types of valleys, the V-shaped valley, the flat floored valley and the U-shaped valley.

How do u-shaped valleys form?

U-shaped valleys have steep sides and a wide, flat floor. They are usually straight and deep. They are formed in river valleys which, during the ice age, have been filled by a large glacier . They are formed when glaciers move through the main valley and cut off spurs.

How U-shaped valley is created?

Definition: U-shaped valleys form through glacial erosion. Glaciation develops in established v-shaped river valleys where the ice erodes the surrounding rocks to create a “U” shaped valley with a flat bottom and steep sides. Glacier movement is driven by gravity.

Why are U-shaped valleys important?

glacial valleys valley is converted to a U-shaped valley because the U-shape provides the least frictional resistance to the moving glacier. Because a glacier has a much greater viscosity and cross section than a river, its course has fewer and broader bends, and thus, the valley becomes straighter and smoother.

What determines the shape of a glacier?

Glaciers begin to form when snow remains in the same area year-round, where enough snow accumulates to transform into ice. Each year, new layers of snow bury and compress the previous layers. This compression forces the snow to re-crystallize, forming grains similar in size and shape to grains of sugar.

Why are river valleys V-shaped?

Rivers begin high up in the mountains so they flow quickly downhill eroding the landscape vertically. The river transports the rocks downstream and the channel becomes wider and deeper creating a V-shaped valley between interlocking spurs .

What are disadvantages of valleys?

A place with less pollution. They live in between of nature. Disadvantages :No or very less internet connection. A risk of landslides.

What is valley and examples?

A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period of time.

What are two types of valleys?

Valleys are one of the most common landforms on the surface of the planet. There are three main types of valleys, the V-shaped valley, the flat floored valley and the U-shaped valley. V shaped valleys are valleys formed by rivers, they have a V-shaped cross-section and very steep sides.

What is an ocean rift?

In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates.

How deep is the Great Rift Valley?

Most of these lakes are deep, some with bottoms below sea level. The Rift Valley varies mostly between 2000 and 3000 feet (600 to 900 meters) in depth, with a maximum of 8860 feet (2700 meters) at the Gikuyu and Mau escarpments.

Why is the Great Rift Valley so important?

The system of rift valleys that characterizes the African continent represents a perfect environment to understand the evolution of mankind; for the important paleoanthropological discoveries in Ethiopia, Kenya, Tanzania, Uganda and Zaire, the African rift valleys are indeed considered the “cradle of mankind”, that is …
