Q.6 (A) A2. Verbal to Non-verbal : (5 marks) (alternative to A1)

Water is a chemical substance that is composed of hydrogen and oxygen (H2O) and is vital for all known forms of life. In typical usage, ‘water’ refers only to its liquid form, but it also has a solid state, ice and a gaseous state, water vapor or steam. Water covers 71% of the Earth’s surface. On Earth, it is found mostly in oceans and other large bodies of water, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor, clouds and precipitation. Oceans hold 97% of surface water, glaciers and polar ice caps 2.4% and other land surface water such as rivers, lakes and ponds 0.6%. Additionally a minute amount of the Earth’s water is contained within biological bodies and manufactured products.
