Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Read the given statements and select the correct option. 
Statement 1 : Reforestation is the process of restoring a forest that once existed but was removed at some point of time in the past.
Statement 2 : Reforestation may occur naturally in a deforested area, however it can be speeded up by planting trees with due consideration to biodiversity that earlier existed in that area.

  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statements 1 and 2 are incorrect.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Reforestation is the natural or intentional restocking of existing forests and woodlands (forestation) that have been depleted, usually through deforestation. Reforestation can be used to rectify or improve the quality of human life by soaking up pollution and dust from the air, rebuild natural habitats and ecosystems, mitigate global warming since forests facilitate biosequestration of atmospheric carbon dioxide, and harvest for resources, particularly timber, but also non-timber forest products. Reforestation usually involves replanting areas of forest which have previously been damaged or destroyed, using native tree species. Sometimes forests are able to regenerate naturally if sufficient trees remain nearby and seeds can be dispersed into the deforested areas via animals or wind. However, areas of forest which have been severely degraded are unlikely to be able to regenerate naturally and need to be replanted by hand using native tree species.

So the correct option is 'both statements 1 and 2 are correct'.

Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Extensive planting of trees to increase forest cover is called

  1. Afforestation

  2. Agroforestry

  3. Deforestation

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

Afforestation is the process of planting a large number of trees for increasing forest cover, while deforestation is the process of cutting trees in large numbers from the forest.

So, the correct answer is 'Afforestation'

Multiple choice evs let's plant trees damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

What is reforestation?

  1. Cutting of trees.

  2. Restocking of the destroyed forests by planting new trees.

  3. Conversion of fertile soil into forest.

  4. Conversion of forest into fertile soil.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Reforestation is restocking of the destroyed forest by planting new trees. We should plant at least as many trees as we cut. Reforestation can take place naturally also.

Thus, the correct answer is option B.

Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Replanting forest at places where they were destroyed is called :

  1. reforestation

  2. desertification

  3. replantation

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

A- Reforestation is natural or intentional restocking of forests that have been depleted mainly due to deforestation or any natural calamity. Reforestation gives boost to the wild life and helps in improving the air quality, climate control, improvement in natural resources and many more advantages for living beings.

Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

  3. land degradation

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Desertification is a type of land degradation in which relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.

Multiple choice commercial applications issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

Which of the following terms defines the prefix 'eco'?

  1. Ecology

  2. Environment

  3. Adaptation

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

The word ecosystem was coined by Tansley a British botanist in 1935. Tansley defined ecosystem as a system resulting from the interaction between biotic and abiotic components of the environment. Biotic components include all living components and abiotic components include all physical factors such as weather, atmosphere, soil, etc. present in the surrounding. Hence the prefix 'eco' means environment.

Multiple choice evs - i dwelling places of animals threatened species need of conservation conservation of soil and wild life

Restoring of the destroyed forests by planting new trees is known as

  1. House keeping

  2. Ecosystem

  3. Afforestation

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

Reforestation can be defined as the establishment of forest by planting trees in those areas where there is no previous forest cover. This can be done either naturally by means of natural seeding or we can go for artificial methods in which the trees are planted or seeding is done directly.

Multiple choice evs - i rules are for everyone sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles

Eco friendly method is

  1. Plantation of C- 3 plants

  2. Plantation of sugarcane

  3. Energy plantation

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

Energy plantation is growing of firewood trees on the non forest and agricultural lands. Plants selected for energy plantation must be local, fast growing, hardy, requiring minimum nutrients, preferably with associated nitrogen fixing organisms, good cropping, good fuel value and having additional benefits like food, fruit, gum etc. It is an eco - friendly energy resource.
