IntroductiontoEnvironment
Whatever we see in our surroundings makes the environment.
For examples, table, chair, school, car, parks, newspaper,
mountains, rivers, trees, clothes, books and so on.
Meaning of environment.
Environment means the surroundings
or conditions in which person, animal,
or plant lives or operates.
OR
Environment is the place, people,
things and nature that surround any
living organism. It is a combination of
natural and human made resources
Componentsof Environment
It has three components:
1) Natural – The natural surroundings. For
example: - Air - Water - Land - Living things
2) Man made – It includes all things made by human
beings. For example: - Buildings - Parks - Bridges -
Roads - Monuments - Industries
3) Human – Includes human related values and
beliefs. For example: - Individual - Family -
Community - Religion - Education - Political situation
- Economic scenarios
Threats To Environment
Threats to environment means anything that can
disturb our natural environment. For instance, man
made things such as fumes are polluting the air;
land is being consumed to build factories; etc.
Biotic and Abiotic
• Biotic – The world of living organisms or all the living things. For
example: Plants, animals, fungi, bacteria, people.
• Abiotic – the world of non – living elements. For example: rocks,
water, air, sunlight, wind, land, soil.
Domainsof theEnvironment
Domains or different layers of the environment includes:
1) Lithosphere – The solid crust or the hard top layer of the earth. It is
made up of rocks, minerals and covered by the thin layer of soil.
2) Hydrosphere – The waters on the earth's surface, such as lakes, seas,
oceans, rivers etc.
3) Atmosphere – It is the thin layer of air that surrounds the earth. It
consists of a number of gases, dust and water vapour. Any change in
the atmosphere produces change in the weather and climate.
4) Biosphere – Plant, animals, water, earth and human life makes the
biosphere also known as the living world.
Ecosystem
An ecosystem includes all of the living things (plants,
animals and organisms) in a given area, interacting
with each other, and also with their non-living
environments (weather, earth, sun, soil, climate,
atmosphere).
