Without Water no Life

Almost all the processes that make up life on Earth can be broken down into chemical reactions -
and most of those reactions require a liquid to break down substances so they can move and interact freely.

Liquid water is an essential requirement for life on Earth because it functions as a solvent.

It is capable of dissolving substances and enabling key chemical reactions in animal, plant and microbial cells.

Its chemical and physical properties allow it to dissolve more substances than most other liquids.

Other characteristics that make it a good habitat for life are its heat conduction, surface tension,
high boiling and melting points, and its ability to let light penetrate it.

Jungblut said, 'As water plays such an essential role in life on Earth,
the presence of water has been vital in the search of other habitable planets and moons'.
