major 4 domains of the earth?
1) Lithosphere =The solid portion of the earth is called Lithosphere.
2) Atmosphere=The gaseous layers that surrounded by earth is called atmosphere.
3) Hydrosphere =water covers a very big area of the earth surface and this area is called the Hydrosphere.
4) Biosphere=The narrow zone where we find land ,water, and air together is called biosphere.

yes your answer is right..
Answer:
The four major domains of the earth are : - Lithosphere, Hydrosphere, Atmosphere and Biosphere.
Lithosphere = A lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of up to thousands of years or more.
Hydrosphere = A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers.
Atmosphere = An atmosphere is a layer of gas or layers of gases that envelope a planet, and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
Biosphere = The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rain forests and high mountaintops. ... Since life exists on the ground, in the air, and in the water, the biosphere overlaps all these spheres.
