The hydrosphere.
The hydrosphere encompasses all of Earth's water.

The biosphere is unique because it is the sphere where life exists on Earth. It encompasses all living organisms and their interactions with the environment. Unlike the other spheres (atmosphere, hydrosphere, lithosphere), the biosphere is where living organisms thrive and play a crucial role in shaping the planet.
Geosphere
The sphere that refers to solid water and ice is known as the "cryosphere." This includes all regions of the Earth where water is in solid form, such as glaciers, ice caps, sea ice, and permafrost. The cryosphere plays a crucial role in regulating the Earth's climate and sea levels. Its changes can significantly impact global weather patterns and ecosystems.
The cryosphere contains all the frozen water on Earth. This includes ice sheets, glaciers, snow cover, sea ice, and permafrost.
The biosphere contains all of Earth's living things.
Troposphere
The water sphere of earth is the HYDROSPHERE.
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.
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.

The largest sphere that can fit around Earth is the geocentric celestial sphere. This imaginary sphere has Earth at its center and encompasses all celestial objects visible in the sky.
The sphere that we all live on is called the Earth. (It is not a perfect sphere, but close enough)
