Water Test - 1

Explanation:

On a clear day, water evaporates from the warm ground into the atmosphere. When night falls, the ground radiates the day's warmth into the skies. The ground becomes much cooler, causing the water vapour to condense. This condensed vapour is dew.

Explanation:

Although water comprises 70% of Earth, only one percent of water is fresh and usable. This one percent of water comes from lakes, rivers, or the ground.

Explanation:

Water change liquid into water vapour (gases) by process of evaporation. Above 100°C Water change in gaseous state.

Explanation:

The definition of inexhaustible resources is a natural resource that is not an endless supply.So water is natural resources which is inexhaustible.

Explanation:

Evaporation can take place at any temperature. However, increasing the temperature of a body of water also often increases evaporation. So Evaporation of water takes place faster in hot condition.

Explanation:

Underground water is made available for human use either as well water or spring water. Well is underground source of water while river, lake and sea are surface source of water.

Explanation:

Water is the only substance on Earth that naturally occurs in three physical states: solid(ice), liquid(water), and gas(water vapour).

Explanation:

Rainwater is the purest form of natural water. While coming down through the air the first showers collect dust particles, germs , bacteria and dissolve some of the gases which are present in the atmosphere. Subsequent showers are free from all these impurities.

Explanation:

The blanket of gas on the surface of a planet or satellite is called atmosphere. The atmosphere of the Earth is roughly eighty percent nitrogen and twenty percent oxygen, with traces of other gases.

Explanation:

Plants need water to grow which they get from soil. They use a part of water to make their food and release the remaining water into the air as water vapour through small pores in their leaves, called stomata. This process is called transpiration.
