Sometimes they seem like a part of some magical unexplored world or the perfect scenery for a fairytale. Caves are one of the most exciting creations of mother nature, full of thrilling and mystical experiences waiting for the explorer’s hungry eyes.
Before we talk about caves and how much we admire them we need to know how were they formed. There are many types of cave in the world and many different ways they have been created.
One example of cave formation is a long process that begins when acid rain, containing carbon dioxide and rainwater, falls to earth. When the acid rain makes contact with the solid rocks in the lower layers of the ground, they start to dissolve.
With rocks made of limestone and dolomite, the chemical process is faster. After the rock dissolves, it creates hollow spaces that fill with rainwater and create underground water bodies like streams and rivers. Erosion and weather conditions also help in cave formation. After a thousand years, the cave could be big enough for a human to enter and after million years there are spectacular cave systems full of stalactites and stalagmites.
