19. Why is soil conservation necessary?
20 How is water a renewable resource? Explain?
Answers
19)Soil conservation is important because it saves the soil through harsh weather and stops erosion. While soil is conservating it's getting more nutrients. The more we conserve soil the more crops grow, then we can sell the crops and get money
20)As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.
