Name the four domains of environment and write short notes on each of them
Answers
Answer:
There are four domains of the environment i.e. the lithosphere, the hydrosphere, the atmosphere and the biosphere. Lithosphere forms the solid part of the earth and contains landforms like plateaus, mountains, plains and valleys.
Answer:
The Lithosphere
The lithosphere, sometimes called the geosphere, refers to all of the rocks of the earth. It includes the planet's mantle and crust, the two outermost layers. The boulders of Mount Everest, the sand of Miami Beach and the lava erupting from Hawaii's Mount Kilauea are all components of the lithosphere.
The Hydrosphere
The hydrosphere is composed of all of the water on or near the planet's surface. This includes oceans, rivers, and lakes, as well as underground aquifers and the moisture in the atmosphere. Scientists estimate the total amount at more than 1,300 million cubic feet.
The Biosphere
The biosphere is composed of all living organisms: plants, animals and one-celled organisms alike. Most of the planet's terrestrial life is found in a zone that stretches from 3 meters below ground to 30 meters above it. In the oceans and seas, most aquatic life inhabits a zone that stretches from the surface to about 200 meters below.
The Atmosphere
The atmosphere is the body of gasses that surrounds our planet, held in place by earth's gravity. Most of our atmosphere is located close to the earth's surface where it is most dense. The air of our planet is 79 percent nitrogen and just under 21 percent oxygen; the small amount remaining is composed of argon, carbon dioxide, and other trace gasses.
