The best answer given between 1hr. will be marked the brainiest

Answer 1

Answer:

LITOSPHERE:

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.

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.

ATMOSPHERE:-

An atmosphere is the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. ... The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.

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.

Answer 2

Explanation:

• Lithosphere - The lithosphere is the outer solid shell of the Earth. ... The lithosphere includes the crust and, below, the uppermost layer of the mantle; it floats on the weaker asthenosphere. There are two types of lithosphere: Oceanic lithosphere, which is associated with Oceanic crust.

• Hydrosphere - A hydrosphere is the total amount of water on a planet. ... 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. It also exists below ground—as groundwater, in wells and aquifers

____________________________________________

• 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
