The upper limit of groundwater is called the water table. It is the minimum depth in the soil at which all pore spaces are filled with water. The process of seeping of water into the ground is called infiltration. Our country is divided into four zones based on the availability of water. The water-rich zone in our country is called the wet zone. The area which gets very little rain is deserts. The method of collecting rainwater and storing it for later use is called water harvesting. The water harvesting method is applicable only during rainy seasons, it falls during summer. Water scarcity results in the loss of the green character of the earth. Overpopulation, water pollution, waste during irrigation for agriculture are some causes of water scarcity. Column A Column B 1. Water table C. Groundwater 2. Groundwater A. Infiltration 3.
