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.

Do valleys have water?
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.”
Do rivers start in valleys?
Streams usually form rivers in the higher elevations of mountains and hills. The areas of depression between hills or mountains are known as valleys. A river in the mountains or hills will usually have a deep and steep V-shaped valley as the fast moving water cuts away at the rock as it flows downhill.
What is a valley without a river?
A dry valley may develop on many kinds of permeable rock, such as limestone and chalk, or sandy terrains that do not regularly sustain surface water flow. Such valleys do not hold surface water because it sinks into the permeable bedrock.
What can be found in a valley?
A valley is a type of landform which usually features as lowland between two higher landforms (which may be mountains or hills). Usually, valleys contain a stream or river flowing along the valley floor.
How do rivers form valleys?
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.
Why do valleys have rivers?

What are 3 facts about valleys?
Fun Facts about Valleys for Kids
The faster the water flows, the deeper the valley it makes. Some valleys are steep canyons. Glaciers, which are huge sheets of ice, make even larger valleys. They slowly move down a mountain, often following a valley already created by a river.
What is the difference between valley and mountain?
is that mountain is a large mass of earth and rock, rising above the common level of the earth or adjacent land, usually given by geographers as above 1000 feet in height (or 3048 metres), though such masses may still be described as hills in comparison with larger mountains while valley is an elongated depression …
Do all rivers flow from mountains?
All rivers and streams start at some high point. The high point can be a mountain, hill, or other elevated area. Water from some source like a spring, snow melt, or a lake starts at this high point and begins to flow down to lower points.
Do all rivers originate from mountains?
All rivers have a starting point where water begins its flow. This source is called a headwater. The headwater can come from rainfall or snowmelt in mountains, but it can also bubble up from groundwater or form at the edge of a lake or large pond.
Where are V-shaped valleys found in a river?
What is a V-shaped Valley? The V-shaped valleys are very common in mountains and hills. The fast flowing rivers with steep gradients create these valleys in the upper course of the river. In V-shaped valley, the first cuts are made by flowing rivers and streams.
Do all rivers flow south?
While it is true that most rivers flow south, some rivers actually flow from south to north. Since the direction of flow is influenced mostly by topography, some headwaters or sources (mountains) are located to the south of the mouth or destination.

What are the flat bottom valley called?
An example of a flat-floored valley is the Nile River Valley. A rift valley forms where the Earth’s crust is spreading or splitting apart. This kind of valley is often narrow, with steep sides and a flat floor. Many rift valleys have been found underwater, along the large ridges that run throughout the ocean.
What is a flat floored valley?
Flat-floored Valley: Definition and Formation
Unlike V- or U-shaped valleys, which are typically bounded by elevated land such as mountains or plateaus, flat-floored valleys are characterized by their location in relatively flat, wide areas of land with little change in elevation.
What is the difference between U-shaped valley and V-shaped valley?
Glacial erosion causes the formation of U-shaped valleys, whereas V-shaped valleys are the result of carving by the rivers through their course. U-shaped valley walls are straighter than V-shaped valleys due to the non-bending glacier’s movement. Glaciers do not get influenced easily by rock hardness as are rivers.
Do valleys have grass?
Today, approximately 10 million acres, or 17 percent of California, is considered valley grassland that contains both non-native annual and native perennial species.
Are lakes fed by rivers?
Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin.
What is River Valley kids?

It falls from the atmosphere as rain or snow. Flowing over ground as runoff or underground as groundwater, water finds its way to a stream and then eventually to the sea. Why do rivers continue to flow, even when little or no rain has fallen?

Why are rivers not straight?
Rivers meander because any small bend in a river tends to grow. Water flowing around a bend in a river is a little like a car speeding around a bend in a road. The water is thrown toward the outside of the turn. That fast-moving water erodes the riverbank on the outside of the bend.
