Read the following para and answer the questions. In many mandals the predominant rocks are not granites but rocks of the Kadapa type of limestones. They are also hard but are greatly broken and have a lot of gaps between them allowing water to accumulate in them. In these rocks, water is usually available between three to fifteen meters below the ground level. Wells are therefore dug up to 16 meters deep.The areas adjacent to the great rivers like the Krishna and the Godavari have deep layers of sand and silt. The water level here depends upon the water in the river. Usually, there is plenty of water. It is nearly five to seven meters below the ground in these areas and it is very easy to dig wells in them. 1. Which rocks are too hard?2. Which rocks have a lot of gaps between them?3.
