Class 6

A tributary is a freshwater stream that feeds into a larger stream, river or other body of water. The larger, or parent, river is called the mainstem. 6 – 12+

The place where a river enters a lake, larger river, or the ocean is called its mouth. River mouths are places of much activity. As a river flows, it picks up sediment from the river bed, eroding banks, and debris on the water.

Rivers of nearly every size have no affect on wind direction, however, the terrain that rivers lie within will affect swirling. Bill. How does a river (30 ft wide) effect your wind, scent? If set-up on a river, can you assume you will get a consistent wind.

In the upper course, the main work of the river is erosion.

The main function of the river in the middle course is transportation of sediments . It becomes a little slow and increases in volume . The major landforms formed by the river in this stage are flood plains , meanders , ox-bow lakes and braided rivers .

Answer. The volume of water in a river is at its greatest in the lower course. This is due to the contribution of water from tributaries. The river channel is deep and wide and the land around the river is flat.

Hint: A river has three basic functions: erosion, transportation and deposition. It is the combination of these three processes that lead to the formation of various landforms by the action of a river.

More importantly, in the present era, river systems have the following potential uses: navigation, water power production, fish culture, water supply, habitation, recreation, industry, commerce and transport, mining, waste water disposal, international borders and harbors.

Rivers always flow downhill, of course! A stream, or a river, is formed whenever water moves downhill from one place to another. This means that most rivers begin high up in the mountains, where snow from the winter, or ancient glaciers, is melting.
