What is the term for where groundwater bubbles or flows out of cracks in rock?

• A. Natural Spring
• B. Oasis
• C. Geyser
• D. Hot Spring

Answer: (A)

Groundwater discharging at the surface through cracks in rock forms a natural spring. When water stored in an aquifer moves and encounters openings in the rock, the pressure pushes it upward and out onto the surface, producing a spring. This is the general term for groundwater that bubbles or flows out where rock fractures reach the surface. A geyser, by contrast, is a specific type of hot spring that erupts periodically due to geothermal heating and pressure buildup in a narrow passage. A hot spring is simply water that is unusually hot, not necessarily erupting. An oasis is a fertile area in a desert sustained by groundwater nearby, but it’s not the term for the surface discharge itself.
