Geomorphic Processes

2,085 Questions

Geomorphic processes shape the Earth surface through physical mechanisms like weathering, erosion, and deposition. This topic covers soil formation, glacial movement, and coastal landform development. It forms a core component of physical geography in major competitive examinations.

Geomorphic Processes Questions

Multiple choice

What is the largest cause of soil erosion?

  1. Flowing water

  2. Stagnant water

  3. Wind

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

While wind and other factors contribute, flowing water is the primary agent of soil erosion globally, as it physically detaches and transports soil particles.

Multiple choice

What type of erosion results in the formation of many small channels?

  1. Rill

  2. Gully

  3. Sheet

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

Rill erosion is characterized by the formation of many small, shallow channels that can often be smoothed over by normal tillage. Gully erosion is the more advanced stage where these channels become too large to be removed by tillage.

Multiple choice

Example of erosion

  1. The water keep hitting the mountain cause a cervices

  2. The water wasted the soil away

  3. the earth split in half

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

Water erosion occurs when flowing water wears away soil and rock, creating features like crevices, channels, and gullies. The example describes water repeatedly hitting a mountainside and creating crevices (correct spelling is crevices, not cervices), which is a clear instance of water erosion.

Multiple choice social science water: a natural resource water table groundwater and depletion of water table the water cycle

The process of seeping out water into the ground is called:

  1. evaporation

  2. infiltration

  3. transpiration

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

The process of seeping out water into the ground is known as infiltration.

 It is process by which water goes into the ground resulting in increase in water table.
The process is not evaporation as it means evaporating the water present on the ground. 
The process is not transpiration as it is the process by which moisture is carried through plants from roots to small pores on the underside of leaves.

Multiple choice

A ridge of land that separates two watersheds.

  1. divide

  2. watershed

  3. river

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

A divide is a high point or ridge of land that determines which direction water will flow into different watersheds. It acts as a boundary between drainage basins.

Multiple choice

The top of the saturated zone is called the

  1. impermeable layer.

  2. water table.

  3. bedrock.

  4. zone of precipitation.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The water table is the upper boundary of the saturated zone, where the soil or rock below is completely filled with water.

Multiple choice geography basic problems of an economy introduction to natural resources (eco) understanding development: perspectives, measurement and sustainability resources - types and conservation

By which of the following erosion, desertification is caused by a maximum amount?

  1. Erosion by rain water

  2. Wind erosion

  3. Erosion by flow of rivers

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

Soil erosion is the loss of top fertile layer of soil either by wind or by water.

India is facing this problem in many parts. The area affected by soil erosion is 5, 00,000 square kilometres. It adversely affects productivity and economy of the country.

If the soil erosion is by wind it is called wind erosion

Desertification is mainly caused by wind erosion

Multiple choice evs - i sources of water the lithosphere and the hydrosphere first aid safety and first aid

The water cycle in nature involves which of the following processes sequentially?

  1. Evaporation, precipitation and condensation

  2. Precipitation, condensation and evaporation

  3. Evaporation, condensation and precipitation

  4. Condensation, evaporation and precipitation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Water evaporates as water vapour from water bodies like lakes, rivers, seas, etc. It then cools as it moves up and condenses to form clouds of tiny water droplets. When the cloud is saturated with warm droplets, precipitation occurs in the form of rain.

Multiple choice evs - i sources of water the lithosphere and the hydrosphere first aid safety and first aid

Water cycles through the biosphere in all of the following processes except     

  1. Precipitation

  2. Condensation

  3. Transpiration

  4. Decomposition

  5. Runoff
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. When the water vapour in the atmosphere condenses and fall in the form of rain, hail, snow etc., it is called precipitation.
B. Condensation is the conversion of a gas into liquid when the temperature is lowered down.
C. Transpiration is the loss of water in vapour form from the surface of leaves through minute pores called stomata.
D. Decomposition is the process of breakdown of complex organic materials into simpler ones.
E. Runoff is the overflow or the flow of excess water over the earth's surface from any water source.
Hence, water cycles through the biosphere in all of the given processes except decomposition.
So, the correct answer is 'Decomposition'.
Multiple choice evs - i sources of water the lithosphere and the hydrosphere first aid safety and first aid

In the water cycle, the process by which water is returned to the atmosphere is known as 

  1. Runoff

  2. Condensation

  3. Evaporation

  4. Precipitation

  5. Photosynthesis
Reveal answer Fill a bubble to check yourself
C,E Correct answer
Explanation

Evaporation and photosynthesis are two process through which water is returned to the atmosphere during water cycle.

So, the correct answer is 'Evaporation and Photosynthesis'

Multiple choice evs - i sources of water the lithosphere and the hydrosphere first aid safety and first aid

................... is one of the ways by which water moves on the Earth.

  1. Condensation

  2. Precipitation

  3. Runoff

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

Runoff is one of the ways by which water moves across earth's surface, it can be both surface runoff and channel runoff. As it flows, the water may seep into the ground, evaporate into the air, stored in lakes or reservoirs, which are then to be extracted for agricultural or other human uses.
