Water is important in many geological processes. Groundwater is present in most rocks, and the pressure of this groundwater affects patterns of faulting. Water in the mantle is responsible for the melt that produces volcanoes at subduction zones. On the surface of the Earth, water is important in both chemical and physical weathering processes
Water in three states: liquid (including the clouds, which are aerosols), solid and gas (water vapour) Water (H 2 O) is a transparent, tasteless, odourless, and almost always colourless chemical substance and covers about 71% of Earth's surface. No known life can live without it. Water is important for our life. [17] This has to be qualified a bit.
Efficient use of water saves the expense of water supply provision and leaves more fresh water in lakes, rivers and aquifers for other users and also for supporting ecosystems. For example, we should not treat toilet as a trash can.
An important feature of water is its polar nature. The structure has a bent molecular geometry for the two hydrogens from the oxygen vertex. The oxygen atom also has two lone pairs of electrons.

Sep 15, 2023 · Water acts as a lubricant in the mouth (through saliva) and the eyes (through tears) to help prevent dryness. It's necessary to produce synovial fluid, which lubricates, cushions, and protects the joints. Water also helps protect the spinal cord and prevents injuries by increasing tissue flexibility and elasticity.

It's clear. It has no taste. It doesn't smell like anything. But if it couldn't do the things it does, life on Earth would not exist. Water is a tiny molecule. It consists of three atoms : two of hydrogen and one of oxygen. Water molecules cling to each other because of a force called hydrogen bonding.
Mar 20, 2015 · 7 reasons why water is vital for a sustainable future. Climate change, extreme weather, health, rapid urbanization, water and sanitation, food security, energy and infrastructure are challenging communities around the world. All of these are expected to be part of the Sustainable Development Goals (SDGs), a global framework to be announced this ...
