What factor causes acid rain in Canada?

Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

What are the greatest contributors to acid rain in Canada?

Nitric acid (HNO3) generated from emissions of nitrogen oxides (NOx) is a significant contributing factor in this region. In Canada, as in many other countries, the majority of NOx emissions are from transportation.

What are the 3 causes of acid rain?

Human activities leading to chemical gas emissions such as sulfur and nitrogen are the primary contributors to acid rain. The activities include air pollution sources emitting sulfur and nitrogen gases like factories, power generation facilities, and automobiles.

What are 2 causes of acid rain?

Sulfur dioxide (SO2) and nitrogen oxides (NOx) released into the air by fossil-fuel power plants, vehicles and oil refineries are the biggest cause of acid rain today, according to the EPA.

Is northern or southern Canada more susceptible to acid rain?

It has been estimated that some 43% of Canada’s land area is sensitive to acid deposition. Areas of Canada which are likely to suffer the most damage are located in Ontario, Quebec and Labrador because of the prevailing westerly winds over most of eastern North America.

How did Canada deal with acid rain?

Canada’s response. Canada created a federal-provincial team to devise a common solution ― the 1985 Eastern Canada Acid Rain Program. It established: An eastern Canada cap of 2.3 million tonnes of Sulphur Dioxide (SO2)in the seven easternmost provinces, to be met by 1994 and maintained until 2000.

What is the main cause of acid rain?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. … In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

Which of the following pollutant causes acid rain Mcq?

It mostly occurs due to the presence of oxides of sulphur and nitrogen in the atmosphere. Nitrogen and sulphur oxides react with water vapour to form acids. Large amounts of sulphur and nitrogen oxides are emitted from power plants and large industries.

What are the main gases that cause acid rain?

Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

What causes acid rain Mcq?

Explanation: Acid rain is mainly caused due to a result of air pollution. … Explanation: The gases of nitrogen oxides and sulphur dioxide react with the tiny droplets of water in clouds to form sulphuric and nitric acid.

Can acid rain burn your skin?

Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this, never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air.

What does acid rain cause to the environment?

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.
