Multiple choice evs mud and stones soil types types of soil soil - types, uses and need for conservation

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

  1. Light soil

  2. Alluvial soil

  3. Heavy soil

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

Sediment refers to solid fragments of inorganic or organic material, that comes from the weathering of rock and are carried and deposited by wind, water, or ice. Sedimentary soil is the transported soil, which is formed in this manner. Alluvial soil is the already formed soil, carried and deposited by flowing water as rivers etc.

What causes erosion of concrete degradation?

  1. Bacterial corrosion

  2. Viral corrosion

  3. Biological damage

  4. All of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bacterial corrosion, specifically through the action of sulfur-oxidizing bacteria, is a primary cause of concrete degradation in sewer systems.

Multiple choice

Part of the water which falls over the surface ends up infiltrating into porous rocks and forming aquifers which are...

  1. Rocky, highly impermeable soils that allow underground water to circulate

  2. Very permeable rocky soils that do not allow groundwater to circulate

  3. Very porous rocky grounds which accumulate groundwater and allow it to flow

  4. Very permeable rocky soils allow river water to circulate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Aquifers are geological formations of porous rock that are capable of holding and transmitting significant quantities of groundwater.

Multiple choice

Water , together with the rest of external geological agents, models the surface of earth where...

  1. Wild waters without channel or flow, circulate on the surface

  2. The streams are of little slope and of regular flow

  3. Karstic modelling finally dissolves granite and creates typical caves

  4. rivers give rise to the littoral modeling that models the surface relief
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wild waters, often referred to as runoff or sheet wash, are geological agents that model the surface of the earth without being confined to a permanent channel. Other options contain inaccuracies, such as karstic modeling dissolving limestone, not granite.

Multiple choice biology natural resources- air, water and land soil - formation and profile soil-nature soil profile

The weathering of rocks is caused by 

  1. Wind, water and climate

  2. Only wind and clay

  3. Only wind and water

  4. Wind, water and gravel
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Weathering is the breakdown of rocks through multiple physical and chemical processes. Wind causes physical abrasion, water contributes through erosion and chemical reactions, and climate (temperature variations, freezing-thawing) creates stresses that fracture rocks over time.

Which of the following occurs as a deposit of river bed?

  1. Sand

  2. Clay

  3. Silt

  4. Silica
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Water contains lots of impurities inside it. it includes fine sand, clay and many other materials present in it. These are carried away by the flow of running water. They are then deposited or sedimented at the bottom of the water reservoirs.
  • This sedimentation forms silt. As it is present at the bottom, it is usually accumulated at the bed of the river. 
  • So, option C "Silt" is the correct answer.
Multiple choice chemistry for a pollution free nature properties of soil soil pollution and its effects soil and soil pollution

Soil erosion is controlled by ________.

  1. planting trees on barren slopes

  2. reducing deforestation

  3. geotextiles

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

Soil erosion is controlled by: 
Using geotextiles is an effective method because it also stabilizes soil
The simplest and most natural way to prevent erosion is through planting vegetation.
Reducing deforestation and substituting chemical manures by animal wastes also helps arrest soil erosion in the long term.

Multiple choice chemistry for a pollution free nature properties of soil soil pollution and its effects soil and soil pollution

What is soil erosion?

  1. It is the process by which soil is formed

  2. A harmful process that involves the removal and transport of soil by wind and water

  3. A natural method of filtering harmful pollutants

  4. A process often referred to as the greenhouse effect
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage. It reduces the quality of soil.

Multiple choice geography rivers, coasts and glaciation river landform landforms created by wind erosion wind and coast

Denudation is a process of wearing away of landmass by various processes like _________.

  1. Weathering

  2. Erosion

  3. Transportation

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Denudation is the wearing away of the surface of the earth. It is a larger process which involves the following
  • 1- Wethering ie breakdown of rocks and other material on earth's surface
  • 2- Erosion - removal of materials on the earth's surface from there original place
  • 3- Transportation - the movement of eroded material to long distances
  • Hence all the options are correct.
Multiple choice geography rivers, coasts and glaciation river landform landforms created by wind erosion wind and coast

______ is a process of wearing away of the earth's surface.

  1. Erosion

  2. Denudation

  3. Wethering

  4. None of thses
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Denudation is the process of wearing away of earth's surface. 
  • Wethering is the process of wearing away of rocks on the surface of the earth.
  • Thus wethering is the subprocess of denudation. Larger process of wearing away of earth's surface refers to Denudation thus it is the right answer.
  • Erosion refers to the removal and movement of the material present on the earth's surface which involves denudation, wethering and transportation, has is not a specific answer.
