Question

Distinguish between river alluvial plains and glacial outwash plains

Answer 1

Glacial Plains are structures formed by the movement of ice from highland areas to low land levels. Slow and continuous takes place over time to cause sizable erosive work to produce a glacial plain. True glacial plains, unlike formed of pure glacial material unlike outwash plains. Marl deposits from a glacial plain are often used to make cement and are great fertilizers as well.

The alluvial plain is formed from weathering caused by water currents in the sea, river or stream. Water flowing down from higher land regions to produce low relief plains. This is what is known as the alluvial plain. These landforms are made up of the deposition of sediment over a long period of time from the fluvial movement to form alluvial soil. An alluvial plain is characterized by its relatively flat and gently sloping landform and is normally formed at the base of a range of hills.

Answer 2

Answer:

Both are extremely large landforms created by the depositional features.

Explanation:

• An outwash plain is a plain formed by the sedimentary deposits by a glacier when it melts, while the alluvial plains are caused by the weathering that is caused by the water currents in the seas, river or lakes. This water flows down the higher lands,  to regions that have low land.

• The outwash plains are also called as the sandar are glacial areas. As there large areas contain a larger amount of silt that picked up and eroded when moving down the hill. They may also contain some kettle lakes.

• The Alluvial plains have alluvial soils that are formed by the higher elevations and form form the natural levees at the margins of the flood channel and the are eroded or have been formed by the shift in floodplains over the geologic time.
