What Part Of The River Is Close To The Mouth?

What is the area at the mouth of a river called?

What is river current?

A river current is the water moving in a river. Rivers flow from high points to lower ones and eventually down to a larger body of water. The force of gravity, which makes the water flow downward, creates river currents. … River currents are influenced by the volume, or amount, of water flowing in a river.

Do all rivers have rapids?

Obviously, for rapids to occur, there needs to be moving water. Rapids form on any kind of flowing water, from tiny creeks to rushing rivers.

Why do rivers have rapids?

So What’s a Rapid? Typical rapids in rivers across the globe are caused by five factors: water, steep gradients, harder rocks, softer rocks, and time. As water runs faster down these steeper sections, the softer rocks erode more quickly than the harder rocks causing a variance in water levels and speeds.

What is a fast flowing water called?

Rapids are areas of shallow, fast-flowing water in a stream. Rapids tend to form in younger streams, with water flow that is straighter and faster than in older streams. Softer rocks in the streambed erode, or wear away, faster than harder rocks.
