1. The correct answer is B. Conservation tillage practices help the soil erosion and also maintains soil nutrient levels.

Conservation tillage is termed as the tillage system which helps to conserve energy, soil, water through retention of crop residue and reduction of tillage intensity.

2. Correct answer is A. Aquifers 1 and 3 may result in a reduced river flow. Aquifer is termed as the underground layer of rock fractures, water-bearing permeable rock.

Hydrogeology is termed as study of water flow which is found in aquifers.

3. Correct answer is A. Recycling materials helps decrease the amount of new material which are taken from environment.

Most household can be recycled. Some other examples which are recycled include textiles, plastics, organics, and metals. Metals such as drinking bottles and food cans which are made from steel and aluminium can be recycled.
