1)How do conservation tillage practices lead to agricultural sustainability? a. Conservation tillage practices reduce the amount of water required to grow crops. b. Conservation tillage practices help reduce soil erosion and maintain soil nutrient levels. c. Conservation tillage practices naturally protect crops from insect damage, reducing the need for pesticides. d. Conservation tillage practices reduce the amount of energy needed to produce crops.

2)Which best describes the aquifers?

Aquifers 1 and 3 may result in a reduced river flow.

Aquifer 2 may result in reduced surface water levels.

Aquifers 2 and 3 may result in decreased wetland and spring discharge.

Aquifer 3 may result in an increase in productivity.

3)How can recycling materials lead to environmental sustainability?

a.

Recycling materials helps decrease the amount of new materials taken from the environment.

b.

Recycling materials helps increase the rate of carbon sequestration.

c.

By recycling materials, the amount of biomass available for energy purposes is increased.

d.

All of the above

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.
