Continuous pumping of water causes drawdown. The water table lowers rapidly.
<u>Explanation:</u>
- Water table is the level below which the ground is saturated with water.
- During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.
- But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.
- To prevent this, the groundwater should be recharged and over drawing should be avoided.

Answer:
Polymers are large molecules with a chain structure that can be linear, branched, and cross-linked. Polymer chains are mainly composed of covalently bonded atoms.
Explanation:
Polymers can be synthesized using reactants of petrochemical or renewable origin. Polymers can be synthesized in two methods, by step-growth and chain polymerization. Both ways of polymerization are random processes during which chains of different lengths are formed.
The basis of step-growth polymerization is the condensation reaction.
