It may lead to drought.

It may lead to flood.

Yes, cutting of trees are responsible for droughts and floods. Cutting of trees disrupts the natural water cycle. trees are natural water tanks. They absorb water during rain. When we cut trees, water can't be absorbed, so it has to go where gravity takes it, which causes flood. Deforestation and soil erosion would dry up the place where it happens, since water isn't absorbed. This causes drought.

Some water pipes burst in winters because during winter, cold develops enormous pressure in the pipes and due to this high pressure, water pipes burst.

We can conserve water by following ways:
(i) Do not waste water and repair all the leaking water taps.
(ii) Do not use drinking water in garden or in cleaning.
(iii) Do not throw any waste in ponds or rivers to prevent their pollution

Engines release large amount of heat. This heat gets consumed in the conversion of water (present in radiator ) into water vapours , therefore engine  parts do not heat up.

Water is called the universal solvent because it dissolves most of the salts and substances in it.

Water is the medium by which plant sucks all necessary minerals from soil , takes food to various parts and absorbs oxygen. Water is also necessary for photosynthesis

Only surface water freezes as ice, but below the frozen surface, temperature does not fall below 4°C. This temperature is optimum for the survival of aquatic animals in arctic region.

Water evaporates from sea, lakes and other water surfaces. Water also evaporates from wet lands, clothes, etc. Water also evaporates from plants through transpiration.

Upto 70% of our body is made by water.

Water cycle is the continuous journey of water from the surface of earth to atmosphere and back.

Photosynthesis is the biochemical reaction in which water reacts to form glucose.

Evaporation is a slow process. In hot regions it might be little fast.

The higher the temperature, the faster will be the rate of evaporation and vice versa.
