Answers
Answer:
1. Lithosphere, Atmosphere, Hydrosphere, and Biosphere
Major domains of the earth is a basic concept in Geography. Solid (Lithosphere), gaseous (Atmosphere), liquid (Hydrosphere) and biosphere parts of earth are not isolated, but they overlap with each other. This article throws light on the 4 Major Domains of Earth; namely Lithosphere, Atmosphere, Hydrosphere, and Biosphere
3.Hydrosphere
The hydrosphere (from Greek ὕδωρ hydōr, "water" and σφαῖρα sphaira, "sphere") is the combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite. Although Earth's hydrosphere has been around for about 4 billion years, it continues to change in shape. This is caused by seafloor spreading and continental drift, which rearranges the land and ocean.
4. The atmosphere plays a very important role in making the planet livable. It protects the life on Earth from the dangerous rays of Sun. Atmosphere traps heat, and make the planet a comfortable place to live. Atmosphere is considered to be vital in maintaining the water cycle.
5. The biosphere plays an integral role to support the life of organisms and their mutual interactions. It is a vital element in climate regulation. Namely, a change in the biosphere triggers a change in climate. Moreover, the biosphere is an integral reservoir in the carbon cycle.
6.Stopping pollution is important for the survival of our planet, and even more importantly, the health and well-being of the people who depend on it. The air we breathe is laden with hazardous contaminants, and our oceans and waterways have been poisoned with chemicals.
