What Is A Stream Valley?

A stream valley is

a depression in the earth with water flowing at the lowest point

. Streams create these valleys due to erosion, which is the movement of broken-down rock or soil from one place to another. The water moves particles from one location to another and changes the land formation around the waterway.

What type of stream valley would form in a mountainous area?

–

A V-shaped valley

is the type of stream valley that is most likely to form in a mountainous area. This is a small valley with a profile that resembles the letter V. The sides of this form of the valley are steeply sloping. It's caused by a stream eroding downward, which is known as downcutting.

What are the 3 types of streams?

• Alluvial Fans. When a stream leaves an area that is relatively steep and enters one that is almost entirely flat, this is called an alluvial fan. …
• Braided Streams. …
• Deltas. …
• Ephemeral Streams. …
• Intermittent Streams. …
• Meandering Streams. …
• Perennial Streams. …
• Straight Channel Streams.

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 streams become graded?

The

factors that make a river larger and the factors that make it smaller balance out

. This is when it becomes a graded stream. … Well, the faster, thinner and steeper parts of the stream erode a lot of material. But the slower, wider, and shallower parts of the stream deposit more material than they erode.

What depositional feature forms when a stream enters a lake or ocean?

A delta

is an accumulation of sediment formed where a stream enters a lake or ocean.

What is the ultimate base level of a stream?

The ultimate base level is

sea level

– streams will not erode their channels below their base level. Many temporary base levels can exist along a stream's path. Erection of a dam results in creation of a lake which serves as the temporary base level for the up stream part of the river.

What factors determine the discharge of a stream?

The discharge of a stream is the product of

its velocity (V – length of travel per unit of time such as feet/second) times depth of the water (D – unit of length) times width (W of the water – units of length)

. (Make sure all all three lengths are expressed in the same unit.)

Are streams faster than rivers?

As a

stream flows faster

, it can carry larger and larger particles. … At flood stage, rivers flow much faster and do more erosion because the added water increases the stream's velocity. Sand, silt and clay size particles generally make up the suspended load for a stream (Figure 10.2).

How does a stream start?

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. … These streams may slowly join together to form a larger stream or river.

What is an example of a valley?

. … A stretch of lowland lying between hills or mountains and usually having a river or stream flowing through it.

What are the features of valley?

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.
