Improve Your Learning

Question 1.
Life itself constitutes a separate sphere called ‘Biosphere’. Explain.
Answer:

• The Earth is a unique planet, in that it has life.
•  It is inhabited by countless forms of life from microscopic bacteria to great banyan trees and animals like lions and blue whales and of course human beings.
• The earth has a combination of land, air and water and a moderate temperature has made life possible on it.
• Various forms of life are not only related to the three spheres around them, but also to one another.
• They influence one another and they are part of a complete “food chain.”
• Hence geographers are of the opinion that “life itself constitutes a separate sphere called ‘Biosphere’.

Question 2.
Why is ecological crisis created in modern times? What are its effects?
Answer:

• These days the increase in population creates great pressure on earth as well as its resources.
• To satisfy the needs of ever growing population systematic mining, cutting of forests, building of forests and fields and roads took place all over the earth.
• Burning of fossil fuels and release of enormous amounts of waste materials by industries contaminate air, water, and soil.
• For providing food for the ever growing population, there is a need for increase in agricultural production.
• Modern agriculture uses a large amount of chemical fertilizers and pesticides.
• The most frightening aspect of pollution due to modern agriculture is the increase in the levels of toxins in our food.
• This increasingly proves to be very harmful not only to humans but also to all types of life on earth.
• Since all living and non-living things on the earth are in one way or the other connected to each other, change affecting one, in due time affects all the others too. All these factors lead to ecological crisis.

Effects of ecological Grisis :

1. If a particular species which feeds upon a particular kind of plant is exterminated, it would result in unchecked growth of that plant and it may intrude the area where other plants grow and disturb their growth.
2. Many industries use chemicals and metals which flow into the rivers and streams. The metals like mercury are consumed by microorganisms in water and in turn beome the food of fishes. When human beings consume these fishes they too absorb some amount of mercury which is detrimental to their health.
3. Farmers use Diclofenac to treat cattle; when the cattle die their flesh retains this chemical: When their flesh is consumed by vultures, diclofenac leads to kidney failure in them and they die.

1. These forests are located in the mid latitudinal costal region.
2. They are commonly found along the eastern margin of the continents.

d) Temperate Deciduous Forests :

1. The temperate deciduous forests are found in higher latitudes.
2. They shed their leaves in the dry season.

e) Mediterranean Vegetation :

1. The west and the south west margins of the continents are covered by these forests.
2. Mediterranean trees adapt themselves to dry summers with the help of their thick barks and wax coated leaves. These help them to reduce transpiration.
3. These regions are marked for hot dry summers and dry summers and mild rainy winters.

f) Coniferous Forests :

1. Coniferous forests are found in the higher latitudes of Northern hemisphere.
2. These forests are found in abundance in the Himalayas.

g) Tropical Grasslands :

1. These forests grow on either side of the equator up to tropics.
2. This vegetation grows in the areas of moderate to low amount of rainfall.

h) Temperate Grasslands :

1. These are found in mid-latitudinal zones and in the interior part of the continents.
2. Usually the grass is very short and nutritious.

i) Thorny Bushes :

1. These are found in the dry desert like regions.
2. This vegetation cover is scarce here because of scanty rain and scorching heat.

j) Tundra :

1. This vegetation is found in the polar region.
2. The growth of natural vegetation is very limited here.
3. Only mosses, lichens and very small shrubs are found here.

Question 7.
Read the paragraph under the title ‘Depletion of Resources’ on page 57 and comment on it.

Industrialisation, rapid population growth and urbanisation all have meant unprecedented exploitation of natural resources like minerals, forests, soil, water, air etc. besides sources of energy (coal, petroleum etc.) stored in the earth for billions of years. This has resulted in rapid deforestation and decline of reserves of minerals, oil and ground water. Many scientists have argued that the present way of life is not ‘sustainable’for if we use so much natural resources, nothing will be left for our children and grand children.

Answer:
Depletion of resources is the consumption of a resource faster than it can be replenished.

Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion.

Resource depletion is most commonly used in reference to farming fishings mining, water and fossil fuels.
