Geomorphic Processes Questions
What is the most common type of soil erosion in India?
-
Sheet erosion
-
Rill erosion
-
Gully erosion
-
Wind erosion
A
Correct answer
Explanation
Sheet erosion is the most common type of soil erosion in India.
What is the term used to describe the slope of a highway?
-
Gradient
-
Camber
-
Superelevation
-
Crossfall
A
Correct answer
Explanation
Gradient refers to the slope of a highway along its longitudinal axis, indicating the rate of change in elevation.
Which of the following is a common problem associated with mountain soils?
-
Erosion
-
Salinization
-
Waterlogging
-
Compaction
A
Correct answer
Explanation
Erosion is a major problem in mountain soils due to steep slopes, sparse vegetation, and intense rainfall events.
How do dams affect the downstream sediment load?
-
They increase the sediment load.
-
They decrease the sediment load.
-
They have no effect on the sediment load.
-
The effect depends on the specific dam.
B
Correct answer
Explanation
Dams trap sediment, reducing the amount of sediment transported downstream.
What is the term used to describe the movement of water through the soil profile?
-
Infiltration
-
Percolation
-
Capillary rise
-
Transpiration
A
Correct answer
Explanation
Infiltration refers to the process by which water enters the soil profile from the surface.
Which drainage method involves constructing terraces or embankments along the contour lines of a slope to control erosion and improve drainage?
-
Surface drainage
-
Subsurface drainage
-
Contour drainage
-
Terracing
D
Correct answer
Explanation
Terracing involves constructing terraces or embankments along the contour lines of a slope to control erosion and improve drainage.
What is the term used to describe the process by which water moves from the soil surface to the atmosphere through evaporation and transpiration?
-
Infiltration
-
Percolation
-
Capillary rise
-
Evapotranspiration
D
Correct answer
Explanation
Evapotranspiration refers to the process by which water moves from the soil surface to the atmosphere through evaporation and transpiration.
How does water contribute to soil erosion?
-
It can cause flooding, which can lead to soil erosion.
-
It can cause landslides, which can lead to soil erosion.
-
It can cause gullies and rills to form, which can lead to soil erosion.
-
All of the above
D
Correct answer
Explanation
Water, in the form of heavy rainfall or flooding, can cause soil erosion through flooding, landslides, and the formation of gullies and rills.
Which type of erosion is caused by the action of wind?
-
Water erosion
-
Wind erosion
-
Rill erosion
-
Gully erosion
B
Correct answer
Explanation
Wind erosion is the process by which wind detaches and transports soil particles, leading to the loss of topsoil and degradation of soil quality.
Which type of erosion is caused by the action of water?
-
Water erosion
-
Wind erosion
-
Rill erosion
-
Gully erosion
A
Correct answer
Explanation
Water erosion is the process by which water detaches and transports soil particles, leading to the loss of topsoil and degradation of soil quality.
What is the term used to describe the process of sea ice breaking up into smaller pieces?
-
Iceberg Calving
-
Ice Floe Formation
-
Sea Ice Drift
-
Ice Jamming
B
Correct answer
Explanation
Ice floes are formed when sea ice breaks up into smaller pieces due to wind, waves, or currents.
What is the term used to describe the process of sea ice breaking away from the coastline?
-
Iceberg Calving
-
Ice Floe Formation
-
Sea Ice Drift
-
Ice Jamming
A
Correct answer
Explanation
Iceberg calving occurs when large pieces of ice break away from glaciers or ice shelves and fall into the ocean.
What is the term used to describe the process of sea ice melting and forming new ice?
-
Iceberg Calving
-
Polynya Formation
-
Sea Ice Extent
-
Ice-Albedo Feedback
C
Correct answer
Explanation
Sea Ice Extent refers to the area covered by sea ice at any given time.
What is the primary cause of coastal erosion?
-
Sea-level rise
-
Human activities
-
Natural processes
-
All of the above
D
Correct answer
Explanation
Coastal erosion is caused by a combination of sea-level rise, human activities, and natural processes such as wave action and storms.
What are some of the human activities that contribute to coastal erosion?
-
Construction of seawalls and other hard structures
-
Dredging and sand mining
-
Removal of vegetation from coastal areas
-
All of the above
D
Correct answer
Explanation
Human activities such as construction of seawalls and other hard structures, dredging and sand mining, and removal of vegetation from coastal areas can all contribute to coastal erosion.
