What is the source of a river BBC Bitesize?

Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. They always flow downhill because of gravity. They then flow across the land – meandering – or going around objects such as hills or large rocks. They flow until they reach another body of water.

What is a river like near its source?

Near the source, a river flows over steep slopes with uneven surfaces. It often flows over a series of waterfalls and rapids. As a river flows down steep slopes, the water performs vertical erosion . This form of erosion cuts down towards the river bed and carves out steep-sided V-shaped valleys.

How are rivers formed short answer?

river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas.

What is a river Short answer?

A river is a ribbon-like body of water that flows downhill from the force of gravity. A river can be wide and deep, or shallow enough for a person to wade across. A flowing body of water that is smaller than a river is called a stream, creek, or brook.

How many rivers are in India?

What is the oldest river in the world?

What Is The Oldest River In The World?

Can a river flow in two directions?

One of their names-Mahicantuck-means “great waters in constant motion” or, more loosely, “river that flows two ways.” It highlights the fact that this waterway is more than a river-it is a tidal estuary, an arm of the sea where salty sea water meets fresh water running off the land.

Do all rivers lead to the ocean?

Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.

Can a lake disappear?

Scientists and explorers have discovered lakes, rivers, and other waterways around the world that seem to disappear entirely. In some cases, sinkholes can cause entire lakes to disappear in a matter of days. In alpine areas and polar regions, cracks in ice sheets can burst glacial dams, draining lakes overnight.

Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.

Are all lakes salty?

D. For starters, lakes and rivers do contain salt, just not as much as the oceans. A large portion of those salts and minerals washes downstream into other rivers, or through the outlet stream or river of a lake, and eventually winds up in the oceans.

Why is the ocean blue?

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.

Can you drink ocean water?

Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body’s kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly.

Is River a freshwater?

Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater.

Where do rivers end?

The end of a river is its mouth, or delta. At a river’s delta, the land flattens out and the water loses speed, spreading into a fan shape. Usually this happens when the river meets an ocean, lake, or wetland.

Is the Salt River salty?

As leaves fall off and the wind blows, salt is dispersed around the surrounding land. Since the salt river is lined by Tamarisk, much of that salt falls into the water, making it salty.
