Answers
Answer:
2)The four realms of earth : lithosphere , hydrosphere , biosphere and atmosphere. lithosphere : the outer most solid layer of the earth that is composed of rocks and soil is known as lithosphere.it is also called the crust of the earth.
3) The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
4) Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth.
5) The Biosphere is a narrow contact zone of land, water and air that supports life.
6) The balance of nature needs to be maintained to acquire a stable equilibrium for the harmonious survival of plants,animals and other living beings together on this planet. This can be achieved by maintaining the proper positive as well as negative feedback systems existing in nature.
