Life on planet earth is dependent on many factors like resources available on Earth, energy from the Sun etc. The different resources available on the Earth are land, water and air. All of these three things are required for the existence of life forms.
Lithosphere The outer crust of the Earth.
This water along with underground water comprises the hydrosphere. The air covering of earth is-called atmosphere. Biosphere The life-supporting zone of the Earth where the atmosphere, hydrosphere and the lithosphere interact and make life possible is known as the biosphere.
Abiotic components The non-living things air, water and soil form the abiotic components of the Biosphere. The Breath of Life Air is a mixture of many gases like nitrogen, oxygen, carbon dioxide and water vapour.
Carbon dioxide is produced in the atmosphere by following activities: Carbon dioxide is fixed in two ways: The role of atmosphere in climate control: Atmosphere keeps the average temperature of the earth steady during the day and whole year.
Atmosphere prevents sudden increase in temperature during daytime and fall of temperature during night. The rate of atomosphere in climate control is the movement of Air, Rain, Air pollution, Water 4. The addition of undesirable substances to water and removal of desirable substances from water is called water pollution.
The main causes of water pollution are as follows: Mineral richss in the soil: Soil is the most important natural resource which supplies nutrients to the life forms.
Soil is formed by weathering of rocks in thousands of years. Following factors are responsible for making soil from rocks.
Some organisms like lichen and mosses grow on the surface of rocks and they release certain substances that cause weathering of rocks and a thin layer of soil is formed.Conservation and Use of Natural Resources BIOLOGY Notes MODULE - 4 Environment and Health (a) Natural resources (b) Artificial resources.
