Explain the connection of different sphers for the survival at tro on earth? (7 marks)
Answers
Answer:
The area near the surface of the earth can be divided into four interconnected spheres: lithosphere, hydrosphere, biosphere, and atmosphere. Think of them as four interconnected parts that make up a complete system; in this case, of life on earth. Environmental scientists use this system to classify and study the organic and inorganic materials found on the planet.
The Lithosphere
The LithosphereThe 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 sands of Miami Beach, and the lava erupting from Hawaii's Mount Kilauea are all components of the lithosphere.
The Hydrosphere
The HydrosphereThe 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 about 1.3 billion cubic kilometers
The Biosphere
The BiosphereThe 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 AtmosphereThe 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% nitrogen and just under 21% oxygen; the small amount remaining is composed of argon, carbon dioxide, and other trace gasses.
Explanation:
All four spheres can be and often are present in a single location. For example, a piece of soil will contain minerals from the lithosphere. Additionally, there will be elements of the hydrosphere present as moisture within the soil, the biosphere as insects and plants, and even the atmosphere as pockets of air between soil pieces. The complete system is what makes up life as we know it on Earth.
