Multiple choice evs - i rules are for everyone soil and its conservations soil pollution-control protecting our environment sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles

Which one of the following is not a method of soil conservation?

  1. Mulching

  2. Overgrazing

  3. Strip cropping

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

Soil conservation is the process of prevention of soil erosion and to prevent the soil from becoming infertile.  In mulching, a protective layer is placed over the soil such as straw, grasses etc., which helps in retaining soil moisture and also regulates soil temperature. Strip cropping is a process in which field is divided into strips and different crops are grown in alternate strips to preserve soil fertility. Crop rotation means growing of different types of crops on the same field in succession which prevents the depletion of nutrients from the soil. Overgrazing or intense grazing will erode the soil.

Thus, the correct answer is option B.

Multiple choice commercial studies striving for a better environment soil and its conservations soil pollution-control protecting our environment

Soil conservation can be best achieved by having a

  1. Wind screens

  2. Good plant cover

  3. Restricted human activity

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

Anthropogenic soil erosion is caused by removal of plant cover through over grazing, litter collection, tree felling, leaving the soil unprotected during agricultural operations. Anthropogenic factors remove green cover and expose the soil to natural agents of soil erosion i.e., water and wind. When rains fall, most of the top layer of soil is washed away, if the soil is not covered by vegetation. 

Conservation of soil can best be achieved through good green cover over soil.

Mulching is helpful in

  1. Increasing soil fertility

  2. Improvement of soil structure

  3. Moisture conservation

  4. Better crops
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mulching refers to the covering of harvested field with plant litter or polythene of low density, in order to decrease run off, prevent the growth of weeds and retention of water. It protects the roots from seasonal variations.During initial stages of growth, mulching helps to maintain a stable temperature for proliferation of seedling.

Multiple choice commercial studies striving for a better environment soil and its conservations soil pollution-control protecting our environment

Which of the following prevents soil erosion?

  1. Allowing herbivorous animals to graze excessively.

  2. Growing plants to form a soil cover.

  3. Increasing fertility of the soil.

  4. Making the land slopy.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When trees are cut on a large scale land becomes barren. This results in the loss of upper soil layer due to heavy wind or flowing water leading to soil erosion. Roots of plants hold the soil particles and prevent their loss. Hence afforestation i.e. growing plants to form a soil cover prevents soil erosion. Thus the correct answer is option B.

Multiple choice evs - i rules are for everyone soil and its conservations soil pollution-control protecting our environment sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles

Soil conservation is achieved through

  1. Restricted human activities

  2. Good plant cover

  3. Wind screen

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

Soil erosion is removal of top soil by agency of water (water erosion) and wind (wind erosion). Soil erosion is of two types- natural and anthropogenic. 

Natural or geological erosion is extremely slow removal of top soil due to rain water or wind. 
Anthropogenic soil erosion is caused by removal of plant cover through over grazing, tree felling, leaving the soil unprotected during agricultural operations. 
Thus, soil conservation can be achieved through good plant cover.

Multiple choice commercial studies striving for a better environment soil and its conservations soil pollution-control protecting our environment

Soil erosion can be prevented by

  1. Restricted human activity

  2. Good plant cover

  3. Checking movement of animals

  4. Wind screen alone
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Soil erosion is the phenomenon in which the top most layer of soil gets lost, since plants have the capability of holding the soil particles together and prevent them from being eroded away

So, the correct answer is 'Good plant cover'

Process of soil conservation involves 

  1. Addition of fertilisers

  2. Aeration of soil

  3. Ploughing

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

Soil conservation is the prevention of soil from erosion or reduced fertility, caused by overuse, acidification, salinization or other chemical soil contamination. Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, that affect both erosion and fertility.

C Correct answer
Explanation
Soil conservation is the prevention of soil from erosion or reduced fertility caused by overuse, acidification, salinization or other chemical soil contamination. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas.

Terracing is an effective method of soil conservation in

  1. Desert areas

  2. Plain areas

  3. Hill areas

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Terracing is a soil conservation practice applied to prevent rainfall run-off on sloping land from accumulating and causing serious erosion. Terraces consist of ridges and channels constructed across-the-slope. The major benefit is the conservation of soil and water. Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus, permits more intensive cropping than would otherwise be possible
So, the correct answer is 'Hill areas'

All the following are proper plans for increasing agricultural production except

  1. Expansion of irrigation facilitles

  2. Increase in application of fertilizers

  3. Mechanisation of various aspects offarming

  4. Cutting of forests to add land for cultivation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cutting of forests also called as deforestation that can provide additional area for cultivation. However, this is an incorrect plan because it leads to decrease in the number of trees. This will in turn lower rainfall and hence decrease the agricultural production. Thus the correct answer is option D.

Which of the following is not a method of preventing soil erosion?

  1. Terrace farming

  2. Contour ploughing

  3. Strip cropping

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The prevention of soil erosion is called as soil conservation and the ways can be as follows:
Terrace farming is one way to do so and involves cutting terraces along a slope. These terraces reduce the speed of water flowing down the slope and help in soil conservation.
Contour ploughing is also beneficial in reducing the flow of water down the slope and involves ploughing at right angles to the natural slope of land.
Effective farming techniques further help in soil erosion. In plain areas, strip cropping can be used for soil conservation where strips of grass are allowed to stand between crops in large fields. These strips of grass reduce the force of wind and thus prevent soil erosion.
