EXERCISE 1: SPELEOLOGY (UNDERSTANDING CAVE FORMATION)
In this exercise, you will observe what happens to chalk in different solutions and compare your observations to what occurs in nature.
1. Do the results of the exercise support your hypothesis? Explain your reasoning.
2. Compare and contrast the reaction of the chalk pieces in each solution.
3. Is this exercise an analog for physical or chemical weathering? Explain your reasoning.
4. Using your observations of the chalk in different solutions, explain how a limestone cave forms.
