Burning of fossil fuels that release sulphur and nitrogen compounds into the air is identified as the major cause of acid rain in the united states.
<h3>What are the causes of acid rain?</h3>
- Acid Rain is created when sulphate and nitrogen oxides from the atmosphere react with rainwater and fall as a result. 
- Sulphur and nitrogen particles that mix with the wet elements of rain are the main causes in the production of acid rain. 
- Due to air pollutants, notably the excessive levels of sulphur and nitrogen released by machinery and industrial operations, acid rain is made up of water droplets that are extremely acidic. 
- The emissions that are released from industries are man-made causes. 
- The natural causes, such as lightning strikes in the atmosphere that release nitrogen oxides and volcanic eruptions that release sulphur oxide.

Embryology provides evidence for evolution because during their development, many organisms look similar, suggesting that very different organisms may have a common ancestor.
