Hello. This question is incomplete. The full question is:
"Which statement best describes a spring?
the top of the saturated zone
an underground layer of rock or sediment that holds groundwater
groundwater flowing naturally to the surface where it is lower than the water table
a vent in Earth’s surface that periodically ejects a column of hot water and steam"
Answer:
groundwater flowing naturally to the surface where it is lower than the water table
Explanation:
A spring can be characterized as groundwater flowing naturally to the surface where it is lower than the water table.
In other words, we can define a spring as the result of an aquifer that has an amount of water so abundant that it caused it to overflow to the surface of the earth, causing an underground water flow. As already mentioned, this usually happens in regions where the terrestrial surface is lower than the groundwater.
