  3. Nutrient cycle

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

The water cycle (or hydrological cycle) describes the continuous movement of water on, above, and below the surface of the Earth through various states and locations.

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

_______ or _______ refers to the large - scale movement of loose materials down the slope on account of gravity.

  1. Mass Movement

  2. Mass Wasting

  3. Both a and b

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mass wasting, which is sometimes called mass movement or slope movement, is defined as the large movement of rock, soil and debris downward due to the force of gravity. In other words, the earth's outer crust is being 'wasted' away on a 'massive' scale and falling to lower elevations.

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

The phenomenon of the deposition of materials in the lowlands is called _______________.

  1. Aggradation

  2. Degradation

  3. Weathering

  4. Gradation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Deposition of materials in lowlands which causes the filling up of the land and its upliftment is called Aggradation. Hence option A is correct.
  • Degradation is the lowering of the land.
  • Wethering is the breakdown and wearing away of rocks.
  • Gradation is the levelling of the land.
Multiple choice geography rivers, coasts and glaciation landforms created by wind erosion wind and coast denudation river landform

Which of the following processes is responsible for forming the sand dunes in western Rajasthan?

  1. Mechanical weathering

  2. Erosion by water

  3. Wind erosion

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

Sand dunes are landforms created by the accumulation of sand. In arid regions like western Rajasthan, wind acts as the primary agent, transporting and depositing sand to form dunes.

Which agent of denudation causes 'Loess'?

  1. Underground water

  2. Sea waves

  3. Winds

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

Loess is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Winds transport fine particles over long distances and deposit them to form extensive loess plains.

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

The rivers, glaciers, underground water, winds and waves are known as ___________.

  1. agents of weathering

  2. agents of denudation

  3. internal forces

  4. agents of deposition
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Denudation is the process of lowering and leveling of the earth surface by gradual breaking and wearing away of such earth’s features. The agents which promote these breaking and lowering of the earth’s surface are called the agents of denudation.  Examples of agents of denudation are wind, running water, ice and waves.

What is mass movements?

  1. When weathered particles move down due to gravity alone

  2. When chemical reaction takes place between water and iron

  3. When oxidation takes places between rocks

  4. None of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When weathered particles move down due to gravity alone, the process is called mass movement. Mass movement occur in two ways; it is rapid on sleeper slopes while it is slower on gentle slopes.

In periglacial regions along the slopes, small layers of soil accumulate because of the movement of soil. This is called ____________.

  1. Solifluction

  2. Erosion

  3. Landslide

  4. Slumping
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In periglacial regions along the slopes, small layers of soil accumulate because of the movement of soil. This is called solifluction.

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.

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

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
Reveal answer Fill a bubble to check yourself
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.
