Specialized

: hidrosfera

The concept of water (which in its totality may be called the hydrosphere) may be one of the most integral of all concepts related to life and the earth and thus is critical to achieving an understanding of the complexity and interrelatedness of earth systems.

Examples

There is evidence in the hydrosphere, atmosphere, and of course cryosphere.

And it took quite a while for it to cool down to establish the hydrosphere and the, the, the globe as it's known today.
While that cycle can affect how heat is moved around in the atmosphere (and hydrosphere), ultimately the heat must be lost to space via radiation, and the rate at which it is lost is set by the Stefan-Boltzmann Law applied using the temperature of the effective radiating level.

In the early Universe, as new generations of stars formed using the nuclear reaction products of the old, planets like ours formed with them—and sound waves surged and echoed through their structures and their atmospheres and, later, their hydrospheres too.

The hydrosphere includes all the water on Earth, such as oceans, rivers, and lakes.
Scientists study the hydrosphere to understand how water interacts with the atmosphere and climate.

hydrosphere singular

hydrospheres plural

Morphology

hydrosphere = sphere (semi-transparent) = hydro + sphere

The word is built from the combining form 'hydro-' plus 'sphere', and the meaning is largely compositional but technical.

Etymology

Hydrosphere comes from Greek parts hydro- ('water') and sphere ('globe'). So, it means the 'globe of water' around Earth — all the oceans, rivers, lakes and the water in the air.
