Which one among the following processes is not part of a chemical weathering?

  1. Hydration

  2. Exfoliation

  3. Oxidation

  4. Solution

B Correct answer
Explanation

Exfoliation involves the removal of the oldest dead skin cells on the skin's outermost surface. Exfoliation is involved in all facials, during microdermabrasion or chemical peels. It is not a chemical weathering.

In Western plateau region, the vast areas of broken rock and stone, where winds have removed all the loose, light material, are known as the _______.

  1. Inselbergs

  2. Gibber plains

  3. Ayers rocks

  4. Regs

D Correct answer
Explanation

Regs are vast, stony deserts or plains in arid regions where wind has removed the finer, lighter material, leaving behind a surface of broken rock and gravel.

Regarding Abrasio, a weathering process, choose the correct statement(s):
(1) It is a wearing down process related only to fluvial erosion.
(2) Friction is the prime force responsible for abrasion.
(3) Attrition is same as abrasion in all respects.

  1. Only 1

  2. Only 2

  3. Only 3

  4. 2 and 3

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Abrasion is the mechanical wearing down of rock surfaces by friction caused by materials carried by agents like wind, water, or ice. It is not limited to fluvial erosion, and attrition is the wearing down of the transported particles themselves, not the surface.

Geomorphically, what all processes lead to sculpting a landscape?
(1) Weathering 

(2) Erosion
(3) Deposition.

  1. Only 1

  2. Only 2

  3. 1 and 2

  4. All of these

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Landscapes are sculpted by the combined effects of weathering (breaking down rocks), erosion (removing material), and deposition (accumulating material). All three are fundamental geomorphic processes.

Match the following

List I(Phases of Denudation) List II(Description)
(A) Weathering (1) disintegration of rocks
(B) Erosion (2) wearing away by agents of denudation
(C) Transportation (3) removal of eroded material to new place
(D) Deposition (4) dumping at some place where accumulation takes place.
  1. A-1; B-2; C-3; D-4

  2. A-3; B-1; C-2; D-4

  3. A-4; B-1; C-2; D-3

  4. A-2; B-1; ; C-4; D-3

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Weathering is the disintegration of rocks in situ. Erosion is the wearing away by agents. Transportation is the movement of material. Deposition is the accumulation of material.

Salinisation occurs when the irrigation water accumulated in the soil evaporates, leaving behind salts and minerals. What are the effects of salinization on the irrigated land?

  1. It greatly increases the crop production

  2. It makes some soils impermeable

  3. It raises the water table

  4. It fills the air spaces in the soil with water

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Salinization leads to the accumulation of salts in the soil, which can alter soil structure, making it dense and impermeable, thereby hindering water infiltration and root growth.

With respect to chemical weathering a denudational process, choose the correct statements.
(1) It may weaken or entirely dissolve certain constituent of rocks.
(2) In granite, which is made up of quartz feldspar and mica, feldspar easily weathers away.
(3) Loosened material, as in example of granite, quartz and mica are eroded.
(4) Weathered material as in case of granite, feldspar forms regolith, basis of soil.

  1. 1 and 2

  2. 2 and 3

  3. 1, 2 and 3

  4. All of these

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Chemical weathering breaks down minerals like feldspar into clay (regolith), while quartz remains resistant. The loosened material is then susceptible to erosion. All statements provided are accurate descriptions of these processes.

  2. 3 and 4

  3. 1, 2 and 3

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Denudation is influenced by a wide range of factors, including the geological structure, the relief of the land, climatic conditions, and human activities that alter the landscape.
