The hydrosphere.
The hydrosphere encompasses all of Earth's water.
contains solvent salinity
Water covers approximately 70% or more of the water on Earth. Salt water covers most of the surface on the earth's water supply. Amazingly only 3% of all water on earth is freshwater.
Geosphere
The Celestial Globe (or sphere) is an imaginary sphere around our planet, earth. All objects in the sky and space, such as satellites, can be thought inside this invisible sphere.
cryosphere
The biosphere contains all of Earth's living things.
Troposphere
I have never heard of the word 'lydrosphere'. I think you mean 'hydrosphere'. The hydrosphere is the sphere of ther Earth , that contains water ( oceans, Seas ). The Earth is in layers or spheres , like an onion, the hydrosphere is that layer(sphere) that contains all the water . Remember 'hydra' from Classical Greek means 'Water'. There is also the Atmosphere, and the biosphere. they all overlap.
Troposphere
The hydrosphere encompasses all of Earth's water.
A globe represents Earth's entire surface.
Earth's four major spheres are the lithosphere, biosphere, atmosphere, and hydrosphere. The lithosphere contains all of the cold, hard solid land of the planet's crust The biosphere contains all the planet's living things. The atmosphere contains all of the air in the Earth system The hydrosphere contains all the solid, liquid, and gaseous water of the planet.
contains solvent salinity
Geosphere: The geosphere includ all the multed and solid rocks it is made up of the earth's solid crust.
This area is called the Biosphere. It contains all ecosystems around the earth.
The sphere that we all live on is called the Earth. (It is not a perfect sphere, but close enough)
