Defination of natural resources and draw a diagram of natural resources and some examples like biosphere, air, and rain

Answer»

A N S W E R :

Life on earth depends on resources LIKE soil, water, air and energy from sun.

Uneven heating of air over land and water - bodies causes winds.

Evaporation of water from water - bodies and subsequent condensation gives us rain.

POLLUTION of air, water and soil affect the quality of life.

We need to CONSERVE our natural resources and use them in a sustainable manner.

Various nutrients are used again and again in a cycle fashion. This leads to a certain balance between the various components of the BIOSPHERE.

❍ Natural Resources :

Natural Resources : The resources AVAILABLE on the earth and the energy from the sun are necessary to meet the basic requirements of all life forms on the earth.

The stocks of nature which are useful to mankind are known as natural resources.

${\rm\blue{E.g.,}}$ air, water, soil, minerals etc.

❍ Biosphere :

Biosphere : All living things on earth together with atmosphere, the hydrosphere and the lithosphere interact and make life possible is known as biosphere. It may be :

Biotic components : Plants and animals.

Abiotic components : Air, water and soil.

❍ AIR :

• Air is a mixture of different gases.

• Air contains oxygen which is essential to living organisms for respiration So it is called breath of life.

Role of Atmosphere :

• Air is a bad conductor of heat. It keeps the average temperature of the earth constant during the day and even during the course of the whole year.

• Prevents the sudden increase in temperature during day time and during the night, it slows down the escape of heat into our outer space. E.g., At moon, there is no atmosphere and so the temperature varies from $\large{\bf{190°C}}$ to $\large{\bf{110°C}}$ .

The Movement of Air : Winds :

• During the day, the direction of wind is from sea to land. This is because the air above the land gets heated faster and starts rising.

• During the night, the direction of wind is from land to sea. This is because at night, both land and sea start to cool.

• The movement of air from one region to the other creates winds.

❍ RAIN :

• Rain is formed by evaporation and condensation of water through water cycle in which distribution of water takes place. Rain is very important because it carries out all the agriculture processes in the plants.

• So we should conserve rain by contracting dams, pools, etc.

Air Pollution :

• An increase in the content of harmful substance (pollutants) in the air like carbon dioxide, carbon monoxide, oxides of sulphur, nitrogen, fluoride, lead, nickel, arsenic and dust particles etc. causes air pollution. It may cause :

In humans : Respiratory and renal problems, high blood pressure, eye irrigation, cancer.

In plants : Reduced growth degeneration of chlorophyll, mottling (patches/spots of colour) of leaves.
