A spring is an outlet for underground water in limestone. When rainwater falls on the ground, it can seep into the soil and rocks below the surface. If the rock layers below the surface are made of limestone, which is a porous rock that can be dissolved by water, the water can flow through cracks and fissures in the rock, creating underground channels and reservoirs. When the underground water reaches the surface through an opening in the ground, it creates a spring. Springs are important sources of fresh water for plants, animals, and humans, and they can also create unique ecosystems where specialized plants and animals thrive.
