Chapter Notes

Geomorphic Processes

  • Definition: Geomorphic processes refer to the endogenic and exogenic forces causing physical stresses and chemical actions on earth materials, leading to changes in the earth's surface configuration.
  • Endogenic Processes: Driven by internal earth energy, including diastrophism and volcanism, affecting crustal movements and landform creation.
  • Exogenic Processes: Powered by solar energy and gravity, including weathering, erosion, and deposition, modifying the earth's surface.

Endogenic Processes

  • Diastrophism: Involves processes that move, elevate, or build up portions of the earth's crust, including orogenic (mountain building), epeirogenic (continental building), earthquakes, and plate tectonics.
  • Volcanism: Movement of molten rock (magma) onto or toward the earth's surface, forming intrusive and extrusive volcanic structures.

Exogenic Processes

  • Weathering: Breakdown of rocks through mechanical, chemical, and biological processes.
    • Chemical Weathering: Involves solution, carbonation, hydration, oxidation, and reduction.
    • Physical Weathering: Depends on forces like gravitational, expansion due to temperature changes, and water pressures.
    • Biological Weathering: Involves organisms contributing to mineral removal and physical changes.
  • Mass Movements: Gravity-driven movements of rock debris, including landslides, slumps, and debris flows.
  • Erosion and Deposition: Involves the removal and transportation of materials by agents like water, wind, and ice, leading to landscape changes.

Soil Formation

  • Process: Development of soil through weathering and biological activity.
  • Soil-forming Factors:
    • Parent Material: In-situ or transported deposits influencing soil texture and composition.
    • Topography: Affects exposure to sunlight and drainage.
    • Climate: Involves moisture and temperature influencing chemical and biological activities.
    • Biological Activity: Vegetative cover and organisms contribute to organic matter and nitrogen fixation.
    • Time: Duration of soil-forming processes determining soil maturity and profile development.

Key Concepts

  • Gradation: Wearing down of relief variations through erosion.
  • Denudation: General term covering weathering, mass wasting, erosion, and transportation.
  • Enrichment: Concentration of valuable ores through weathering processes.
  • Pedogenesis: Soil formation process, reliant on weathering mantle as the basic input.

Multiple Choice Questions

A.

Increased erosion

B.

Deposition of sediments

C.

Formation of a new river channel

D.

Chemical weathering
Correct Answer: B

Solution:

When the velocity of a river decreases, it loses kinetic energy, leading to the deposition of sediments it was carrying.

Chapter Concept:

Erosion and Deposition

A.

By providing parent material.

B.

By influencing topography.

C.

By adding organic matter and aiding in nitrogen fixation.

D.

By controlling the climate.
Correct Answer: C

Solution:

Biological activity contributes to soil formation by adding organic matter, which aids in humus formation, and through processes like nitrogen fixation, which enriches the soil.

Chapter Concept:

Soil Formation

A.

It involves the folding and faulting of the Earth's crust leading to mountain building.

B.

It includes the movement of molten rock to the Earth's surface.

C.

It is the process of wearing down landforms through erosion.

D.

It is the transportation of sediments by geomorphic agents.
Correct Answer: A

Solution:

Diastrophism refers to the processes that move, elevate, or build up portions of the Earth's crust, including orogeny (mountain building) and epeirogeny (continental uplift).

Chapter Concept:

Endogenic Processes

A.

Epeirogeny

B.

Orogeny

C.

Volcanism

D.

Deposition
Correct Answer: B

Solution:

Orogeny involves mountain building through severe folding, affecting long and narrow belts of the earth's crust.

Chapter Concept:

Geomorphic Processes

A.

Chemical weathering

B.

Physical weathering

C.

Biological weathering

D.

Hydration
Correct Answer: B

Solution:

Physical weathering, particularly thermal expansion and contraction, would dominate in regions with significant temperature fluctuations and minimal precipitation, as chemical reactions require moisture.

Chapter Concept:

Weathering

A.

Erosion by running water

B.

Deposition of sediments

C.

Volcanic activity

D.

Mass wasting
Correct Answer: A

Solution:

In regions where there is both intense rainfall and tectonic uplift, erosion by running water is likely to dominate. The rainfall provides the kinetic energy necessary for water to erode and transport materials, while tectonic uplift continuously provides fresh material to be eroded. This combination leads to significant landscape evolution through erosion.

Chapter Concept:

Erosion and Deposition

A.

Gravitational force

B.

Geomorphic agents like water or wind

C.

Removal of support from below

D.

Overloading due to heavy rainfall
Correct Answer: B

Solution:

Mass movements are driven by gravity and do not involve geomorphic agents like water or wind, which are involved in erosion.

Chapter Concept:

Mass Movements

A.

Diastrophism

B.

Volcanism

C.

Erosion

D.

Deposition
Correct Answer: C

Solution:

Erosion is an exogenic geomorphic process that involves the wearing down of the Earth's surface through the removal and transportation of rock debris by agents like water, wind, and ice.

Chapter Concept:

A.

Gradients prevent the movement of geomorphic agents.

B.

Gradients enhance the mobility of geomorphic agents, facilitating erosion and deposition.

C.

Gradients have no effect on exogenic processes.

D.

Gradients only affect the movement of tectonic plates.
Correct Answer: B

Solution:

Gradients create conditions for geomorphic agents like water and wind to move, leading to erosion and deposition.

Chapter Concept:

True or False

Correct Answer: False

Solution:

While weathering aids mass movements, it is not a pre-requisite for them. Mass movements can occur on both weathered and unweathered slopes.

Chapter Concept :

Mass Movements

Correct Answer: False

Solution:

Deposition occurs when geomorphic agents lose their velocity and energy, leading to the settling of materials.

Chapter Concept :

Erosion and Deposition

Correct Answer: True

Solution:

Diastrophism includes processes such as orogeny, epeirogeny, earthquakes, and plate tectonics, which move, elevate, or build up portions of the Earth's crust.

Chapter Concept :

Endogenic Processes

Correct Answer: True

Solution:

Endogenic processes are responsible for elevating or building up parts of the Earth's surface, contributing to landform creation.

Chapter Concept :

Endogenic Processes

Correct Answer: False

Solution:

Deposition occurs when erosional agents lose their velocity and energy, causing the materials they carry to settle. It is not directly performed by geomorphic agents but is a consequence of their loss of energy.

Chapter Concept :

Erosion and Deposition

Correct Answer: False

Solution:

While weathering aids erosion by breaking down rocks, it is not a prerequisite for erosion, which can occur independently through geomorphic agents.

Chapter Concept :

Solution:

Volcanism is an endogenic process driven by internal Earth energy, including geothermal gradients and heat flow.

Chapter Concept :

Endogenic Processes

Correct Answer: True
