Groundwater is water present under the ground. Groundwater is obtained from handpumps and tube wells. Drought is caused due to the scarcity of water for a long time which leads to the imbalance of the water cycle. Rainwater harvesting is one of the methods for conserving water. Rooftop rain harvesting is the traditional method of collecting rainwater. Sea water is the surface water and it is saline water or salty water. A whale is an aquatic animal that lives in water. Whales are warm-blooded mammals. Flood is the overflow of water from the water bodies which leads to soil erosion. Hydrilla is a water plant that lives in water. Hydrilla is a hardy, fast-growing, perennial with long, slender stems. Its small leaves are strap-like and pointed. Rainwater is one of the sources of water and it is the purest form of water.
