Before attempting the quiz, you may read an overview of the topic given below which will make you feel easier to answer the questions.

Overview:

A forest is the home to many animals and plants. A forest has several benefits for man . Trees purify the air by absorbing carbon dioxide and checking global warming by absorbing carbon dioxide gas from the air. Forests also increase rainfall , check floods and prevent soil erosion. Many animals including mammals, reptiles, insects and birds live in the forest. Tropical rainforests of the world contain the highest number of animal and plant species in the world. They are also called the Lungs of the planet. Many products like wood, timber , spices, gums, resins, dyes, honey, bamboo, lac and rubber are obtained from the forests. Leaves of trees like Tendu and Sal have also special use and , hence, provide livelihood to native people. However, people used to cut trees of the forest for timber, fuel and furniture. Deforestation should be prevented and afforestation should be encouraged. The Government has enacted The Forest Conservation Act in 1980 and established several national parks and sanctuaries to protect and conserve forests.

Forests help in controlling the global warming by absorbing carbon dioxide from the air which is a main greenhouse gas. How do the greenhouse gases produce global warming ?

1 point

Greenhouse gases being good conductors of heat allow more radiant heat from the Sun to enter our atmosphere.

By radiating more heat radiations to the air.

By trapping the heat radiations received from the Sun

Greenhouse gases can become easily hot by the Sun's heat because of their green nature.

Forests act as natural absorbers of rain water. The soil, held by roots of trees , soaks in the rain water. What is the role of the large portion of rain water that seeps down through the soil ?

1 point

They again come back to the atmosphere in the form of water vapour through the process of transpiration..

They recharge the ground water.

They are available to the roots of the plants to survive.

Clear selection

The process of soil being washed away by water or blown away by winds is called Soil erosion. How does a forest prevent soil erosion ?

1 point

Trees increase the fertility of the soil thereby preventing soil erosion.

Trees increase the moisture content of the soil thereby preventing soil erosion.

Trees bind soil particles with their strong roots thereby preventing soil erosion.

Trees increase the humus content of the soil thereby preventing soil erosion.

Clear selection

How does the forest prevent floods?

1 point

The roots of trees prevent soil from being eroded which in turn, absorbs running water to decrease the menace of floods.

The trees of the forest offer a natural barrier for the flood water to enter.

The trees of the forest decreases the speed of the running water of the flood.

The leaves of the trees absorb the flood water thereby decreasing its ferocity.

Clear selection

How does a forest bring about good rainfall ?

1 point

The trees help in the condensation of water vapour resulting in good rainfall.

The trees , because of their huge transpiration, maintain the water vapour level nearly constant in the air which, in turn, produces good rainfall.

Roots of the trees of a forest retain the moisture content of the soil increasing the amount of water vapour in the air.

Tall trees of the forests obstructs the passing clouds bring down copius amount of rainfall.
