GEOLOGY

Detailed explanation-1: -A community decides to upgrade its water purification and management systems. What lasting impact could this have on available freshwater? It could cause an increase in the freshwater supply.

Detailed explanation-2: -Nutrient pollution, which includes nitrates and phosphates, is the leading type of contamination in these freshwater sources. While plants and animals need these nutrients to grow, they have become a major pollutant due to farm waste and fertilizer runoff.

Detailed explanation-3: -A decrease in precipitation can reduce soil moisture over the short term and increase soil erosion rates over the long term.

Detailed explanation-4: -Which change would best aid a farmer in making the transition from conventional farming techniques to more sustainable farming techniques? Rotate the types of crops grown. Which would most likely cause a reduction in the amount of coal and natural gas on Earth? A continual increase in the number of people on Earth.

Detailed explanation-5: -No-till farming can build climate resilience by enhancing soil health. Healthy soil has a higher water-holding capacity, meaning it can better absorb and hold on to water during periods of heavy precipitation and drought, making farms more resilient to extreme weather.
