Geomorphic Processes Questions

Multiple choice geography rivers, coasts and glaciation rivers rivers and their work exogenic forces

Exogenetic process includes _________.

  1. weathering

  2. erosion

  3. mass wasting

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The exogenetic forces or processes are originated from the atmosphere. These forces are continuously engaged in the destruction of the relief features created by the endogenertic forces through their weathering, erosion, mass movement.

What is the name given to the group of weathering processes associated with the action of organism _____________.

  1. Physical weathering

  2. Mechanical weathering

  3. Biological weathering

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

Biological weathering refers to decomposition and disintegration of rocks due to organic material of both flora and fauna. Production of different kinds of organic acids such as humic acids, baterial acids, microfaunal acids etc produced by organic materials help in the decomposition and disintegration of rocks and soils.

Weathering is the process of breaking up the rocks by weather changes such as _____________.

  1. Moisture

  2. Precipitation

  3. Temperature

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in weather conditions like temperature, moisture, precipitation, are all agents of weathering.

Multiple choice geography rivers, coasts and glaciation rivers rivers and their work exogenic forces

Which sequence of processes occurs in the correct order?

  1. Erosion, weathering, transportation

  2. Erosion, transportation, weathering

  3. Weathering, erosion, transportation

  4. All of these processes occur at the same time.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • The correct sequence of events of the soil erosion process is weathering, erosion, transportation.
  • Weathering: It is a process by which small rocks are broken down into further smaller pieces.
  • Erosion: The small fragments of rocks or dust formed by weathering process is moved by wind or water.
  • Transportation: This is the process by which the sand or rock fragments are carried on to the other places.

The erosion of soil by river mainly depends upon its ________________.

  1. width

  2. length

  3. speed with which it flows

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

The erosive power of a river is directly related to its kinetic energy, which is determined by its mass (volume) and the square of its velocity (speed).

Erosion, transportation and deposition are factors of _________.

  1. River

  2. Soil

  3. Both a and b

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

Erosion is the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it away to another location. The particulate breakdown of rock or soil into clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by its dissolving into a solvent, followed by the flow away of that solution. Eroded sediment or solutes may be transported just a few millimeters, or for thousands of kilometers.

Natural rates of erosion are controlled by the action of geomorphic drivers, such as rainfall or bedrock wear in rivers or coastal erosion by the sea and waves or glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows.

Erosion and transportation are both maximum when ________ is high.

  1. Velocity

  2. Volume

  3. Density

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

Stream velocity is the primary factor controlling the capacity of a river to erode and transport sediment. Higher velocity increases the kinetic energy available for these processes.

Multiple choice geography migration and urbanisation urbanisation and people urbanisation : causes and consequences population and settlement

In settlement patterns, settlements that occur near rivers, coasts and railways are classified as ______.

  1. Linear settlement patterns

  2. Zonal settlement patterns

  3. Economic settlement patterns

  4. Climatic settlement patterns
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In settlement patterns, settlements that occurs near rivers, coasts and railways are classified as linear settlements. In this type of settlement houses are built on the side of roads or tracks. This type of settlement is followed mainly to make the transportation easier.

Multiple choice geography population and settlement urbanisation and people urbanisation : causes and consequences industrialisation and urbanisation

In settlement patterns, settlements that occur near rivers, coasts and railways are classified as _____________.

  1. Linear settlement patterns

  2. Zonal settlement patterns

  3. Economic settlement patterns

  4. Climatic settlement patterns
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A linear settlement is a settlement that is formed in a long line. It follows a transport route, such as a road,  river, canal, coastlines, mountains, hills or valleys. A linear settlement has no obvious center. The linear settlement has a long and narrow shape.

Multiple choice evs soil : our life soil profile soil- our life soil and crops

Soil formed by transportation of disintegrated parent material from one place to another is called

  1. Light soil

  2. Alluvial soil

  3. Heavy soil

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

Sedimentary soil is formed by the accumulation and deposition of disintegrated parent material that has been transported from its original location by agents like water, wind, or ice.
