which is not a cause of acid rain in Canada? rivers are produce hydroelectricity, vehicle emissions, or power plants that burn coal
Rivers producing hydroelectricity is not a cause of acid rain in Canada. Acid rain is primarily caused by vehicle emissions and power plants that burn coal.
To determine which option is not a cause of acid rain in Canada, we need to understand what acid rain is and how it is formed.
Acid rain refers to rain, snow, or any other form of precipitation that has a high level of acidity, usually caused by pollutants in the atmosphere. It occurs when pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) react with water, oxygen, and other chemicals in the atmosphere to form various acidic compounds.
Now, let's analyze each of the options you provided:
1. Rivers that produce hydroelectricity: This option does not contribute to acid rain. Hydroelectric power generation uses the force of flowing water to produce electricity and does not emit significant amounts of pollutants that lead to acid rain.
2. Vehicle emissions: Vehicle emissions, especially from fossil fuel combustion, release sulfur dioxide, nitrogen oxides, and other pollutants into the atmosphere. These emissions can contribute to the formation of acids and hence contribute to acid rain.
3. Power plants that burn coal: Coal combustion is a significant source of sulfur dioxide, nitrogen oxides, and other pollutants that contribute to acid rain formation. When coal is burned, sulfur in the coal reacts with oxygen to produce sulfur dioxide, which can then react further to form sulfuric acid. Therefore, power plants that burn coal are a major cause of acid rain.
Based on this information, the option that is not a cause of acid rain in Canada is "Rivers that produce hydroelectricity."
Remember, to answer questions like these, it's important to understand the concepts behind the topic and analyze the information given for each option.
