______ 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.

The process of loosening and turning of soil is called as

  1. Irrigation and manuring

  2. Digging and winnowing

  3. Tilling or ploughing

  4. Harvesting and storage
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The process of loosening and turning of soil is called as tilling or ploughing. This is done by using a plough. It improves the soil quality by increasing aeration. It control the weeds. Therefore, option C is correct.

The blowing away of loose soil in large quantity is known as ____________.

  1. Gully erosion

  2. Sheet erosion

  3. Wind erosion

  4. Soil erosion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The blowing away of loose soil in large quantity is known as soil erosion. Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed.

Wearing down of top soil is called _________.

  1. Washing

  2. Erosion

  3. Corrosion

  4. Denundation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

B. Erosion

Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. One of the main causes of soil erosion is water erosion, which is the loss of topsoil due to water.

Multiple choice zoology ecosystems decomposition in ecosystem ecosystem productivity and decomposition producers, consumers and decomposers

Passage of minerals from top soil to subsoil through seepage of water is known as

  1. Leaching

  2. Percolation

  3. Conduction

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

Leaching is the process where water-soluble substances, such as minerals, are washed out from the topsoil into the lower soil layers (subsoil) by percolating water.

Multiple choice zoology ecosystems decomposition in ecosystem ecosystem productivity and decomposition producers, consumers and decomposers

Downward passage of mineral, from upper soil layer to lower soil strata is called

  1. Percolation

  2. Leaching

  3. Weathering

  4. Runaway
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A liquid when slowly passes through a filter, this is called percolation.

Leaching is the natural process by which water soluble substances (such as calcium, fertilizers, pesticides) are washed out from soil or wastes in the downward passage from upper soil layer to lower soil strata.
Breakdown of rocks at the Earth's surface, by the heavy rainfall, extremes of temperature, and biological activity is called weathering.
Runaway is the passing of soil and other substances by rain.
Thus, the correct answer is option (B).

An arc-shapped ridge, comprising well-sorted sand is called ________.

  1. Sand dunes.

  2. Barchans.

  3. Loess.

  4. Mushroom rock.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • A barchan or barkhan dune is a crescent-shaped dune. 
  • These are also called Crescent dunes.
  •  A Barchan dune is an arc-shaped sand ridge, comprising of well-sorted sand grains.
  • Barchans face the wind, appearing convex and are produced by wind action predominately from one direction.
  •  They are a very common landform in sandy deserts all over the world and are arc-shaped, markedly asymmetrical in cross section, with a gentle slope facing toward the wind sand ridge, comprising well-sorted sand.
Multiple choice geography the soil soil erosion (geo) soil erosion, soil conservation and uses of soil soil erosion and conservation

Which one of the following methods is most appropriate to check soil erosion on steep slopes?

  1. Shelter belts

  2. Mulching

  3. Terrace cultivation

  4. Multi-river project
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The most appropriate method to verify soil erosion on steep slopes is terrace cultivation.Terrace farming is a method of farming whereby “steps” known as terraces are built onto the slopes of hills and mountains. When it rains, instead of rain carrying away the soil nutrients and plants down the slope, they flow to the next terrace. Every step has an outlet which channels water to the next step.

Which of the following is the most effective method of soil conservation of hill slopes?

  1. Afforestation

  2. Construction of terraces

  3. Construction of check-dams

  4. Identification of the type of sand
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Afforestation is the most effective method for soil conservation on hill slopes because tree roots bind the soil together, preventing erosion caused by water runoff.
