Tell the difference between the independent variable and the dependent variable.

Independent is the thing you change and the dependent is what changes because of the thing you change.

Example:

If you had 2 cookies available you'd only have 2 people while if you had 200 cookies than you would have way more people. So the independent would be amount of cookies and the dependent would be how many people show up.

Hope this helps!

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
