Question

Choose the incorrect statement from the following. Forest fires are due to -

• A. Carelessness of human being
• B. Heat of sun
• C. Cutting of tress
• D. lightning strikes

Answer 1

The correct option is C

Cutting of tress

The explanation for the incorrect option:

Option (C): Cutting off trees

1. Deforestation is the change of a forest into a barren landscape as a result of large-scale tree cutting.
2. Plants release oxygen while absorbing greenhouse gases. As a result, cutting down trees could contribute to global warming. Changes in temperature can have an impact on which species can survive in a given ecosystem.
3. When the soil is exposed to the sun's heat, the moisture inside the soil evaporates. Nutrients evaporate, affecting microbes that help in the decomposition of organic materials. As a result, rain washes the soil surfaces, causing erosion.
4. The cutting of trees has resulted in the extinction of many species of plants and animals.
5. It is not a cause of forest fire but a cause of deforestation, greenhouse effect, extinction of species, etc.
6. Hence, it is an incorrect option.

The explanation for the correct option:

Option (A): Carelessness of human being

1. Forest fires are frequently caused by human irresponsibility. The most prevalent cause of man-made forest fires is smoking near plants and discarding the cigarette into dry vegetation without extinguishing the flames.
2. Arson or planned fires are another major sources of forest fires. As a form of revenge, many individuals set fire to forests.
3. Hence, it is the correct option.

Option (B): Heat of the sun

1. Forest fires are influenced by temperature indirectly. The climate becomes dryer as the temperature rises. If a forest catches fire for any reason, it will spread quickly due to the dry climate, dry leaves, and dry tress.
2. Hence, it is the correct option.

Option(D): Lightning of trees

1. Lightning is one of the most common sources of natural forest fires.
2. Lightning strikes dry grass, resulting in a fire in the whole forest as dry trees and leaves catch fire easily.
3. Hence it is the correct option.

Therefore, Cutting trees is not a cause of forest fire.
