Emissions of sulphur and nitrogen dioxides into the air Emissions of carbon dioxide into the air Emissions of copper sulphates into the air

2 Where do human-sourced sulphur and nitrogen dioxides come from?

The combustion of fossil fuels The burning of the rainforests Volcanic eruptions

3 Normal rain ranges between pH 5.5 to 7. What pH is acid rain? (pH goes from 1 acid, to 14 alkaline)

Less than 5.5 Greater than 7 From 4 to 10

4 Which of these is NOT an effect of acid rain on soils?

The soils become more friable and easier to plough Soil toxicity may increase due to mobile aluminium Soils can become leached of nutrients Acid weathering of rocks increases

5 How is acid rain affected by soil organic matter?

Soil organic matter helps increase acidity Soil organic matter helps buffer and absorb acids Soil organic matter is unaffected by acidity

6 How does acid rain affect trees?

Tree growth becomes more healthy and vigorous Nobody knows yet! Trees can become more prone to disease

7 How does acid rain affect waterbodies like lakes and rivers?

The water acidifies and is more toxic to aquatic life Water becomes clearer and more transparent Waters flow more slowly
