What are valleys characteristics?
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 does a valley look like in geography?
valley, elongate depression of the Earth's surface. Valleys are most commonly drained by rivers and may occur in a relatively flat plain or between ranges of hills or mountains. Those valleys produced by tectonic action are called rift valleys. Very narrow, deep valleys of similar appearance are called gorges.
What is the shape of a valley?
Valley glaciers carve U-shaped valleys, as opposed to the V-shaped valleys carved by rivers. During periods when Earth's climate cools, glaciers form and begin to flow downslope. Often, they take the easiest path, occupying the low V-shaped valleys once carved by rivers.
Are valleys flat?
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.
How do you explain valley to a child?
A valley is a long depression, or ditch, in Earth's surface. It usually lies between ranges of hills or mountains. Most valleys are formed by rivers that erode, or wear down, soil and rocks. This process takes thousands or millions of years.
What are 3 facts about valleys?

What is a valley landscape?
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 is an example of a valley?
The valleys are totally enclosed by higher terrain, and rivers or streams within them may terminate in a lake. Some examples of valleys that are wholly surrounded by higher ground and do not open to the ocean include Death Valley in California and the Jordan River Valley in the Middle East.
How big is a valley?
Such valleys can be up to 100 km (62 mi) long, 4 km (2.5 mi) wide, and 400 m (1,300 ft) deep (its depth may vary along its length). Tunnel valleys were formed by subglacial water erosion. They once served as subglacial drainage pathways carrying large volumes of melt water.
