A Correct answer
Explanation

Soil erosion is a phenomenon in which soil of an area eroded due to deforestation, over-grazing, unplanned irrigation, etc., decrease the fertility of soil.

Afforestation is necessary for:

  1. soil conservation

  2. soil erosion

  3. well control

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

Afforestation is the process of planting trees, or sowing seeds, in a barren land devoid of any trees to create a forest. The benefits of this practice, which is called agroforestry, are:

  1. It provides a supply of timber, fruit, and fodder for cattle apart from crop production
  2. It prevents soil erosion and thus conserves soil.
  3. It enables better retention of water
  4. It shields crops from excessive wind and sun damage

In terms of the environmental benefits, planting trees is always beneficial whether it takes place in a barren land or is used as a method to regenerate a depleted forest. Trees help check atmospheric carbon dioxide; large scale afforestation can curb the problems caused due to burning of fossil fuels, industrialization and so forth.

Afforestation and reforestation is a measure mainly to control _________.

  1. soil pollution

  2. water pollution

  3. thermal pollution

  4. none of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Afforestation is the establishment of a forest or stand of trees in an area where there was no previous tree cover.
Reforestation is the reestablishment of forest cover, either naturally (by natural seeding, coppice, or root suckers) or artificially (by direct seeding or planting).

Which of the following properties of soil decreases due to deforestation?

  1. Nutrient content

  2. Fertility

  3. Texture

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

Deforestation is a major cause which leads to the change in soil properties. It affects the nutrient content (which cannot be replenished in the soil), texture and fertility of soil (due to erosion).

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

Which one of these are not the direct cause for soil erosion?

  1. Deforestation

  2. Temperature extremes

  3. Solid wastes

  4. Acid rain
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Soil erosion occurs when the weathered soil particles are dislodged and carried away by wind or water. Deforestation, agricultural development, temperature extremes, precipitation including acid rain, and human activities contribute to this erosion. Humans speed up this process by construction, mining, cutting of timber, over cropping and overgrazing. It results in floods and cause soil erosion.

Deforestation leads to an increase in the water holding capacity of the soil.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. The less the soil is covered with vegetation, mulches, crop residues, etc., the more the soil is exposed to the impact of raindrops. When a raindrop hits bare soil, the energy of the velocity detaches individual soil particles from soil clods. Thus Deforestation would decrease the water holding capacity of the soil, so statement is false and Option B is correct.

The main cause of land degradation in Punjab is _____.

  1. Intensive cultivation

  2. Over irrigation

  3. Deforestation

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

In the states of Punjab, Haryana, western Uttar Pradesh, intense cultivation is responsible for land degradation due to waterlogging leading to increase in salinity and alkalinity in the soil. 

Multiple choice social science production in a factory - a paper mill production in a paper mill information technology industry automobile and electronic industries

What led to the disappearance of bamboo near paper mills?

  1. Climate change

  2. Pollution

  3. Excessive cutting of bamboo

  4. Global warming
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Paper mills are generally established near forests where bamboo and other soft wood trees are available. Paper mills engage contractors to supply bamboo and other raw materials. Due to excessive cutting in the past, there are no bamboos available in forests near the paper mills now.
