The results of deforestation is/are:

  1. the reduction in water content of the soil

  2. the increase in water content of the soil

  3. drier climate

  4. increases moisure content of air
Reveal answer Fill a bubble to check yourself
A,C Correct answer
Explanation

The water cycle is affected by deforestation.Trees extract groundwater through their roots and release it into the atmosphere. When part of a forest is removed, the trees no longer transpire this water, resulting in a much drier climate.Deforestation reduces the content of water in the soil and groundwater as well as atmospheric moisture. The dry soil leads to lower water intake for the trees to extract.Deforestation reduces soil cohesion, so that erosion,flooding and landslides ensue.

If deforestation is done in large scale, this natural calamity may occur

  1. Volcanic eruption

  2. Earthquakes

  3. Global warming

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

If deforestation is performed, there will be no trees so, the amount of the greenhouse gasses will increase in the atmosphere. These greenhouse gasses trap heat from the infrared radiation in the atmosphere and increases the atmosphere's temperature i.e, global warming. 

Thus, the correct answer is option C.

The easiest way to improved the denuded forests of teak in India in to.

  1. Apply mycorrhiza

  2. Apply fertilizer

  3. Add bacterial culture

  4. Use green algae
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mycorrhiza are symbiotic fungi that associate with plant roots, significantly improving nutrient uptake (especially phosphorus) and water absorption, which helps in the growth and survival of teak in denuded areas.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Forests and biodiversity is key to all life forms. The richer the diversity of life, the greater the opportunity for medical discoveries, economic development and adaptive responses to such new challenges as climate change.
Forests are renewable resources which provide
(a) Habitat, food, protection to wildlife.
(b) Help in balancing CO$ _2$ and O$ _2$ of atmosphere.
(c) Improves water holding capacity of soil.
(d) Regulates water cycle.
(e) For human being, they are the source for all essential commodities like, fuel wood, timber pulp and paper etc.
(f) It provides useful products like fruits, resins, gums, essential oils, bidi wrapper etc. 
Therefore, the correct answer is option D.

What is not useful to increase agriculture production?

  1. Mechanisation of agriculture

  2. Enhanced irrigation facilities

  3. Use of fertilizers

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

Deforestation is the excessive cutting down of the trees which adversely affects the environment. It is not useful for increasing the agricultural production as because it creates several major problems like soil erosin, infertility, and droughts.

What are the advantages of reforestation?

  1. It helps to reduce the concentration of CO$ _2$ in the environment.

  2. It has the potential to preserve endangered species.

  3. It can reverse the damage done by erosion.

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

Deforestation results in an increase in CO$ _2$ concentration in the atmosphere, greenhouse gasses like CO$ _2$ and methane significantly contribute to a changing climate. Reforestation involves the planting of the trees of same species. It is an effective method to reduce CO$ _2$ in the atmosphere, it also helps in restoring habitat loss and also helps in fighting against climate change and help in restoring endangered species from extinction.

Thus, the correct answer is option D.
