Multiple choice geography rivers, coasts and glaciation landforms created by wind erosion wind and coast denudation river landform

The process by which the weathered materials do not move downward but sink in situ is called _____________.

  1. solifluction

  2. slumping

  3. landslide

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Slumping in simple terms is recurring downward movements of rock debris. Slump is slipping of one or several units of debris with a backward rotation with respect to the slope over which the movement takes place. Thus, it is the process by which the weathered materials do not move downward but sink in situ.

Which factors determine the deposition of sediments?

  1. Slope of the river

  2. Amount of sediments

  3. Length of river and volume of water

  4. All of above

D Correct answer
Explanation

The factors that determine the deposition of sediments are the length of the rivers, volume of water, amount of sediments, and the slope of the river and the earth's surface.

When weathered particles move down due to gravity alone, the process is called ____________.

  1. weathering

  2. landslide

  3. solution

  4. mass movement
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When gravity alone causes rock or sediment to move down a slope, the erosion is called mass movement. This process is also known as mass wasting. It is a process where a mass of rock debris down the slope under the direct influence of gravity. Weathering is not essential for mass movement, though it helps mass movement. Mass movement has two major classes namely:

1) Rapid movements.
2) Slow movements.

In periglacial regions along the slopes, some small layers of soil get accumulated because of the movement of soil, this is called ____________.

  1. slumpinh

  2. solifluction

  3. landslide

  4. rockfall
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Solifluction is a process covered under the slow mass movements. It is a process that involves slow downslope flowing of soil mass or fine-grained rock debris saturated or lubricated with water. It is because permafrost (ground that remains completely frozen) is impermeable to water, soil overlying may become oversaturated and slide downslope under the pull of gravity. Thus, in periglacial regions along the slopes, some small layers of soil accumulated because of the movement of the soil are known as solifluction.

When the base of the headlands get eroded, it give rise to near vertical slopes called ____________.

  1. sea cave

  2. beach

  3. wave cut platform

  4. sea cliff
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sea cliffs are usually formed by the process of weathering and erosion. In coastal areas the sea waves erode away the base of the headland. The part of rock that remains form a sea cliff.

The portion of the land projecting into the sea is called _________.

  1. beach

  2. sea cliff

  3. sand bar

  4. headland
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A headland is an area of land that extends into a large body of water. It is often a cliff or other elevated landform overlooking a sea or ocean. It is formed when a softer rock in pushed or eroded inwards, the hard rocks sticks out in the sea.

Sea cliff, sea caves, lagoons are the landforms created by the action of _______________.

  1. glacier

  2. wind

  3. sea waves

  4. river
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sea forms create erosional and depositional landforms. Steep rocky coast rising almost vertically above sea water is called sea cliff which is very precipitous with overhanging crest. Sea canes are formed by the mechanical erosion of rocks by the action of sea. A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. They form in areas with small tidal range.

The brackish water lying in between the coast and the sand bars is called the ______________. 

  1. beach

  2. sea caves

  3. lagoons

  4. strait
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Lagoons are shallow bodies of water separated from a larger body of water by barrier islands or reefs. In coastal geography, the water trapped between the coast and sand bars is referred to as a lagoon.
