Which of the following comes under the phenomena of mass movement?

A. Soil creep

B. Landslide

  1. Only A

  2. Only B

  3. Both A and B

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

Mass movement or mass wasting is movements of masses of bodies of soil, bedrock, rock debris, soil, or mud which usually occur along steep-sided hills and mountains because of the pull of gravity. This slipping of large amounts of rock and soil is seen in landslides, mud slides, and avalanches.

Landslides occur when masses of rock, earth, or debris move down a slope. They may be very small or very large, and can move at slow to very high speeds. However, slow movement is also seen in the gradual downhill creep of soil on gently sloping land.

Identify the correct sequence of stages in the water cycle.

  1. Evaporation, condensation, precipitation

  2. Condensation, precipitation, evaporation

  3. Evaporation, precipitation, condensation

  4. Precipitation, evaporation, condensation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Answer is option A i.e. "Evaporation, condensation, precipitation"
There are 3 main stages involved in water cycle i.e. evaporation, condensation, precipitation and runoff. The water cycle starts with evaporation followed by condensation where water vapor converts int liquid water and finally precipitation where liquid water falls from sky in form of rains, snow, hail, etc.

The uniform peeling away of the soil surface by the action of flowing water is called _____________.

  1. Slip erosion

  2. Till erosion

  3. Accelerated erosion

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

Sheet erosion is defined as the uniform removal of a thin layer of soil from the land surface by runoff water. Unlike rill or gully erosion, it does not create distinct channels.

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.
