The atmosphere is the thin layer of air that surrounds the Earth. The gravitational force of the Earth holds the atmosphere around it. It protects us from harmful rays and scorching heat of the Sun. It consists of a number of gases, dust and water vapour. The changes in the atmosphere produce changes in the weather and climate.

Biosphere is a narrow zone of Earth where land, water and air interact for supporting of lives.

Plants and animals are the rwo major components of biotic environment.

The lithosphere is the outermost solid surface of the Earth which made up of rocks and minerals and covered by a thin layer of soil.

Buildings, parks, bridges and roads are four examples of human-made environment.

The environment comprises of three major components
(i) Natural components are land, water, air and living things.
(ii) Human-made components are buildings, parks, bridges, roads, monuments and industries.
(iii) Human components are individuals, religions, political situation, family, education, community and economy.

The natural environment is encircled by the world of living organisms (e.g. plants and animals) and world of non-living things (e.g. land).

Ecosystem is a system formed by the interaction of all living organisms with the physical and chemical factors of the environment in which they live, all linked by transfer of energy and materials.
All plants, animals and human beings depend on their immediate surroundings. This relation between the living organisms and their surroundings form an ecosystem. There could be an ecosystem of large rainforest, grassland, desert, mountain, lake, river, ocean and even small pond. All these components, help in the survival of life.

The various domains of the environment are as follow
(i) Lithosphere It is the solid crust or hard top layer of the Earth. It is made up of rocks and minerals and covered by thin layer of soil. It provides forests, grasslands for grazing, land for agriculture and human settlements.
(ii) Atmosphere It is an envelope of gases that surrounds the Earth which protect us from harmful rays and scorching heat of the Sun.
(iii) Hydrosphere It is a domain of water that comprises various sources of water and water bodies like rivers, lakes, seas, oceans, glaciers, etc.
(iv) Biosphere It is a narrow zone of the Earth where land, water and air interact with each other to support life.
