Answer:

seafloor spreading

Explanation:

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.

alina1380 [7]

Answer: Because more and more agriculture is one of the main "professions", where the use of water is extremely essential. Therefore, there is a great demand for it due to the scarcity that it has been having, since this is a renewable medium.
