Landforms and their Evolution Test - 3

The long axes of drumlins are parallel to the direction of ice movement. They may measure up to 1 km in length and 30 m or so in height. One end of the drumlins facing the glacier called the stoss end is blunter and steeper than the other end called tail. 

The west coast of our country is a high rocky retreating coast. Erosional forms dominate in the west coast. The east coast of India is a low sedimentary coast. Depositional forms dominate in the East Coast.

Cirque are deep, long, and wide troughs or basins with very steep concave to vertically dropping high walls at its head as well as sides.

Bars are submerged features and when bars show up above water, they are called barrier bars.

Outwash plains and eskers form due to the flow of meltwater in front of (outwash plains) or beneath (eskers) that glacier ice. They are composed of glacial sediments that have been reworked by flowing water.

Erosion causes changes on the surface of the earth.

A barrier bar that gets keyed up to the headland of a bay is called a spit.

Natural levees and point bars are depositional landforms of rivers. 

In humid regions, which receive heavy rainfall running water is considered the most important of the geomorphic agents in bringing about the degradation of the land surface. 

Many rock outcrops in the deserts easily susceptible to wind deflation and abrasion are worn out quickly leaving some remnants of resistant rocks polished beautifully in the shape of mushrooms with a slender stalk and a broad and rounded pear-shaped cap above.
