- The amount of water in the rivers and lakes is more than the amount of groundwater.
- The amount of water in polar ice caps and glaciers is more than the amount of groundwater.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer: (b)
Earth is known as the “Blue Planet’’ because 71 per cent of the Earth’s surface is covered with water. Water also exists below the land surface and as water vapour in the air. The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 per cent) is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere.
Distribution of the water on Earth
O Ocean water: 97.2 percent
O Glaciers and other ice: 2.15 percent
O Groundwater: 0.61 percent
O Freshwater lakes: 0.009 percent
O Inland seas: 0.008 percent
O Soil Moisture: 0.005 percent
O Atmosphere: 0.001 percent
O Rivers: 0.0001 percent.
Hence, statement 1 is not correct, but statement 2 is correct.
