I do believe it's known as Hydrosphere. (resource- Earth Science)
the water cycle - evaporation it sucks all the water back up into the earths surface also known as the hydrosphere.
Hydrosphere include water in gaseous and solid state also. For earth, it's almost all liquid.
An earth scientist who studies the hydrosphere is known as a hydrologist. Hydrologists study the distribution, movement, and quality of water on Earth, including rivers, lakes, oceans, and groundwater. They also investigate how these water systems interact with the environment and ecosystems.
The hydrosphere and biosphere interact through the water cycle. Water from the hydrosphere is essential for all life forms in the biosphere, supporting growth, reproduction, and survival. Organisms in the biosphere also impact the hydrosphere through processes like evapotranspiration and pollution.
The hydrosphere is predominantly made out of water, primarily in the form of oceans, seas, lakes, rivers, and other bodies of water. Water molecules, composed of hydrogen and oxygen atoms, make up the vast majority of the hydrosphere.
The water sphere of earth is the HYDROSPHERE.
The hydrosphere includes all the water bodies comprising Earth.
theury of hydrosphere
As of now, Earth is the only known planet with a stable, extensive hydrosphere, characterized by large bodies of liquid water on its surface. While some other celestial bodies, like Europa and Enceladus, are believed to have subsurface oceans, they do not possess a hydrosphere in the same way Earth does. Mars has evidence of past water flow and polar ice caps, but it lacks a significant, stable hydrosphere. Thus, Earth remains unique in its abundance and stability of liquid water.
The most abundant element in the hydrosphere is oxygen, mainly in the form of water (H2O). This is followed by hydrogen, which is also a key component of water.
That's where the water is.
