The Rave about Caves!
What I learned about how Caves Form
CLAY CAVE EXPERIMENT
Clay
First, we flattened our clay.
Sugar cubes
Next, we placed 4 sugar cubes in the middle of our clay. Then, we put the clay around the cubes so they wouldn't fall out.
Water
Last, we put the clay and sugar cubes in a clear cup of water.
WHAT DOES THIS HAVE TO DO WITH CAVES?
SANDSTONE
Sandstone is the outer layer of the cave. It helps protect the limestone, like the clay in our experiment.
LIMESTONE
Limestone is soluble- that means, it dissolves in liquid. This is why we noticed the sugar cubes dissolving.
RAIN
Cracks in caves allows rain to seep in. The acid in the rain is what causes the limestone to dissolve, over a LONG period of time. The clay (sandstone) was left with a large dip in it after the sugar cubes (limestone) dissolved.
