Imagine that you are given a hammer, a small bottle of weak acid, and a piece of limestone about the size of a small, fat dog. Your instructions are to provide a demonstration of the difference between physical and chemical weathering processes. Describe your demonstration.

1) Take the hammer and smash the rock

2) Put acid on the rock

Explanation:

Physical weathering crush a rock's physical structure changing its appearance by friction or impact, therefore, to provide a demonstration of this principle I would take the hammer and smash the rock changing its appearance with the impacts    In contrast, chemical weathering occurs when a chemical reaction of any kind alters a rock's chemical composition changing its appearance through erosion and degradation, therefore, to contrast this phenomenon with the physical weathering I would put acid on the rock to demonstrate the chemical degradation

The answer to the question is gold
