Acid rain is produced when fossil fuels are burned and gas chemicals, such as exhaust from cars and other vehicles that use fossil fuels, are mixed with water vapor in the air that is being evaporated. When that happens the chemicals are rained down with the water vapor the next time precipitation occurs. The precipitation that falls is slightly acidic because of the chemicals that have been mixed with the water vapor which has been rained down. When acid rain mixes with the soil then it is harder for plants to grow.
Here's an experiment! Try it!
shows that acid rain does not help grow plants, but hurt them.
What you need:
* Some grass
* Three small containers
First you put
some soil in the containers. Then you put the seeds in and cover them with
some more soil. Water one with tap water, one with vinegar and water and
one with 1/2 and 1/2. Keep watering them for about six weeks. See the results.
