Most valleys are formed
by erosion of the land surface by rivers or streams over a very long period of time
. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountain or polar areas.
How are valleys and canyons formed?
Canyons and valleys are two landforms created
by running rivers and erosion
. A valley is a depressed area of land between mountains or hills, while a canyon is a deep and narrow valley having steep sides.
How are valleys formed?
These geological formations are created by
running rivers and shifting glaciers
. 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 three main ways that valleys are formed?
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.

Where can valleys be found?
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.
What are the types of valleys?
A valley is a low area of land between hills or mountains, typically with a river or stream flowing through it. 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.
How do valleys affect humans?
Since the beginning of human development, valleys have been an important place for people because
of their presence close to rivers
. Rivers enabled easier movement and also provided resources like water, good soils, and food such as fish.
How do valleys look like?
Valleys are depressed areas of land–
scoured and washed
out by the conspiring forces of gravity, water, and ice. Some hang; others are hollow. … Mountain valleys, for example, tend to have near-vertical walls and a narrow channel, but out on the plains, the slopes are shallow and the channel is wide.
How are valleys important?

fertility and life
; it evokes images of cultivation, and in Chinese symbolism the valley is the yin, shadowy state while the yang is the sunny MOUNTAIN. They are, respectively, the low and the high.
Do all valleys have rivers?
A valley is a landform that is situated between two hills or mountains and is longer than it is wide. Valleys are either U-shaped or V-shaped and their shape and type is characterized by their formation.
Some valleys have rivers running through them
, and are referred to as river valleys.
What is the top of a valley called?
A valley has
a “head”
where it begins in the mountains or hills, “sides” where it rises up on either side, a “floor” which is where the valley is most flat. Some valleys have an “entrance” where the valley opening can be seen between two hills or mountains or cliffs.
What is the world's largest valley?
The San Luis Valley of Colorado
is the largest alpine valley on earth. The Valley floor is approximately 7500 feet above sea-level and surrounded by beautiful mountain peaks many of which are 14,000 foot tall. It is the highest valley in the world capable of sustaining agriculture.
What are three facts about valleys?
- The steeper the mountain, the faster the water flows. …
- Glaciers, which are huge sheets of ice, make even larger valleys. …
- Occasionally, a valley isn't caused by a river or a glacier. …
- Valleys are usually protected from fierce winds and storms.
