Answer: A
Explanation: A stream terrace basically forms through this process– Temporary base level is eliminated; the stream downcuts upstream from the old temporary base level, and the former floodplain is left well above the present elevation of the stream.
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels overtime by not allowing water to INFILTRATE.
Greenhouse gases trap the sun's heat and this is how we can feel it. Without greenhouse gases the earth's average temperature would be 30 degrees less. Other greenhouse gases include water vapor and methane. Increases in the levels of Greenhouse gasses are responsible for present day global warming.
Infiltration is the process by which water enters the soil and eventually becomes part of the groundwater.
