write an Account of various domain of the environment lithosphere, hydrosphere, biosphere, atmosphere
Answers
Explanation:
Imagine that you are walking on a beach, and you feel the sand beneath you. You feel the cool ocean breeze on your face as well as the water of the waves crashing on your feet. the sand is Lithosphere the water is Hydrosphere and the cool breeze that you feel is the Atmosphere. To summarize the major domains are Lithosphere, Hydrosphere, Atmosphere and Biosphere. Let us study them.The lithosphere is a domain concerning land. When land is measured, it is measured by taking sea level as it’s base. The height of the land is also measured by denoting it as either ASL (Above Sea Level) or BSL (Below Sea Level).
For example, Mount Everest, the highest mountain on Earth is 8848 meters above the sea level and this is denoted as ASL (Above Sea Level) while Mariana Trench, deepest part on Earth is 11,022 meters BSL (Below Sea Level). These two constitute the two extremes of Lithosphere. When discussing Lithosphere we must understand the extent of the Continents.
Continents of the Earth .The Earth is divided into 7 continents. Asia, Europe, Africa, North America, South America, Antarctica, and Australia. Continents are the most important domain as they inhibit the largest number of lifeforms.Hydrosphere is a domain that contains water or water bodies. If we take the earth into consideration. Only 1/4th (29%) of the earth is covered in soil/land while the rest 3/4th (71%) portion is covered in water. 97% of the earth’s water is found in oceans and is not suitable for use as it is saltwater.
About the Oceans
Major domains of the Earth

Oceans cover a large part of the globe. There are four primary oceans on Earth, which are Pacific Ocean, Atlantic Ocean, Indian Ocean and the Arctic Ocean.
The Arctic is a polar region located in the northernmost part of Earth. It connects to the Pacific Ocean through a Strait known as Bering Strait that passes through Russia and America. The ‘S’ shaped region between Europe, America, and Africa is the Atlantic Ocean.
The Pacific Ocean extends from the Arctic Ocean in the north to the Southern Ocean in the south. The Pacific Ocean is circular in shape and along the Pacific Ocean, there is a ‘Ring of Fire‘ meaning its an active volcanic belt. Now, the Indian Ocean extends from South Asia to Australia as well as Africa. It has gained a uniqueness due to its wind currents.
Atmosphere

The Atmosphere is a domain that consists of layers which are the troposphere, stratosphere, mesosphere, thermosphere as well as the exosphere. Lifeform sustains on troposphere which is the first layer of the atmosphere. The density of Atmosphere is maximum at sea level and decreases with increasing height. The atmosphere consists of 78% Nitrogen, 21% oxygen and other gases like Argon, Carbon dioxide as well as some other gases comprise 1% of the volume.

Geologist Eduard Suess coined the term “Biosphere” in 1875. The biosphere is the point where all the three domains, viz. land, water and air meet as well as interact with each other. The biosphere is a zone of contact between air, water as well as land.
It is in this zone that life, that is unique to Earth exists and flourishes. The biosphere is divided into two kingdoms, Plant kingdom, and the Animal kingdom. Deforestation and pollution are rapidly damaging the Biosphere.
