Excess rainwater washes leaves, twigs and plants into a cave, providing munchies for insects and other animals. … Bats nest deep inside the cave, and their droppings will pile up several feet high and several feet wide.

What causes a cave in?

Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

What are some threats to caves?

Caves are home to some of the planet’s most unusual creatures and important drinking water supplies. Now these underground resources are being polluted by surface activities, ranging from sewage spills to old factories.

How does weather impact the cave systems?

Cave Climate

Caves, in general, have fairly stable climate conditions. … In winter, once the temperature outside has dropped below the temperature in the cave, cold, usually dry, air plunges into the lower part of the entrance. This cold dry air flows down the large Main Corridor and into the Big Room and Lower Cave.
