Final answer:
Infiltration is the process where surface water moves downward into rock or soil through cracks and pore spaces, which can lead to the replenishment of aquifers and an increase in groundwater.The correct answer is option A.
Step-by-step explanation:
The downward movement of surface water into rock or soil through cracks and pore spaces is known as infiltration. When rain falls on the land, some of it flows over the surface as runoff, which eventually may make its way to bodies of water.
However, another portion of that water seeps into the ground through the process of infiltration. This infiltrated water can move deeper to become groundwater, potentially recharging aquifers. Aquifers are porous rocks that hold water and can be a source of fresh water for drinking or irrigation purposes.
Recharge areas are specific locations where the surface water predominantly infiltrates the ground rather than running off into rivers or evaporating.
Adding water to these recharge areas can lead to an increased amount of groundwater, which is necessary because aquifers are often being depleted faster than they are replenished.
Groundwater can flow slowly through pores and fissures in the soil and rock, eventually finding its way back to the surface water system via streams or lakes.
The natural movement of groundwater also plays a role in cycling minerals like phosphorus and sulfur from land to water which are essential for various ecological processes.The correct answer is option A.
