Which term denotes water that fills the cracks and spaces in underground soil and rock layers?

• A. open water
• B. surface run-off
• C. groundwater
• D. atoms

Answer: (C)

Groundwater is water that fills the pores, cracks, and spaces in underground soil and rock layers. It sits in the saturated zones below the surface and slowly moves through porous materials, forming aquifers that can feed wells and springs. This underground reservoir is different from open water on the surface, like lakes or rivers, and from surface run-off, which flows over the ground after rain instead of sinking down to fill underground spaces. The other terms don’t describe this underground setting: atoms isn’t about water’s location, and open water or surface run-off refer to water on the surface. Groundwater recharge happens when infiltrating water from rain or melted snow percolates down to refill these underground spaces.
