Question

Name three forms of water and define the processes by which they interchange​

Answer 1

Answer:

liquid when the particles are dense

solid when the particles are bounded to each other

gas when the particles are spaced out

Answer 2

Melting is process of solid to liquid. Condensation is from liquid to gas. Freezing is the process of liquid to solid. Evaporation is the process of liquid to gas.

Forms of Water on Earth:-

Water is being continuously used and water conservation is the major concern in the present scenario. The water cycle has helped in maintaining water on the surface of the earth for millions of years. The water circulated in water cycle takes three different forms – solid, liquid and gaseous. The solid form of water – ice, is found at the poles of the earth, the snow covered mountains and the glaciers. The liquid form is present in the rivers, lakes, seas, and oceans. The gaseous form of water, water vapour is present all around us.

Forms of Water

Water present in the oceans and seas evaporate due to the sun’s heat and get converted into water vapour. Ice caps and snow can directly sublimate into water vapour. The atmosphere has lower temperatures in some parts of the world which causes water vapour to condense into tiny droplets. These tiny droplets are heavier than air and therefore may fall if not supported by any uplift. A huge concentration of these tiny droplets results in the formation of visible clouds. The cloud particles collide with dust particles and precipitation occurs.

Precipitation occurs in the form of rain or snow. Rainwater falls on earth and flows to the rivers and lakes and some rainwater is absorbed by the earth’s surface. The groundwater gets replenished by rains. This cycle continues in order to maintain the water balance on the surface of the earth.

The article contains a brief description of various forms of water and the significance of the water cycle in maintaining water quantity.
