Homemade Acid Rain
In a Nutshell

The rocks on earth usually form beneath the surface and then are brought to the surface by volcanic action, earthquakes and the uplifting of earth's tectonic plates. Rocks are then broken down by the effects of summer heating, winter freezing, and erosion from wind and water. The process of creating new rocks and eroding older ones on the surface has been going on since earth's creation and continues today.
Speeding up this natural erosion process is acid rain. When carbon dioxide (one of the gases you exhale) enters the atmosphere it dissolves into atmospheric moisture, causing raindrops in clouds to become naturally acidic.
This is a mild acid but one which can have a large effect over a period of years. The cumulative effect is to dissolve and erode rocks.

Here's an experiment you can do at home to make some homemade "acid rain" and see how chemical erosion works.

Materials Needed:

1. Lemon Juice
2. Vinegar
3. Tap Water
4. Three Cups
5. Three Pieces of White Chalk

Do This:

Put one piece of chalk in a cup and carefully add enough tap water to cover the bottom half of the stick of chalk.
Put a second piece of chalk in cup #2 and add vinegar to the cup until the lower half of the chalk is covered by vinegar.
Place the third piece of chalk into cup #3 and add enough lemon juice to cover half the chalk.

Set the cups aside for 4 days, then come back and remove the chalk sticks and examine them.

What happened?

Can you guess why?

What Really Happened?

Both lemon juice and vinegar are strong acids. White chalk is made of a type of rock called limestone, which contains a chemical called calcium carbonate (CaCO3). An acid will react with the limestone, breaking apart the bond between the calcium and the carbonate to form calcium (Ca) and carbon dioxide gas (CO2). Strong acids will break these bonds rapidly. Weak acids would work more slowly.
Acid rain is significantly weaker than vinegar or lemon juice. Still, as acid rain falls over a period of years, it ends up having an effect similar to that of the vinegar or lemon juice's effect on the chalk. Acidic rain water can, and does, eat away at rocks, causing them to erode and crack. Moisture in the cracks may then freeze during the winter months, expanding as the water freezes, making the cracks even larger and exposing even more surface area to the acid rain and further erosion.
