Question 1

Normal rain and snow have a pH of what?

Answer 1

A pH of 5.6

Question 2

Precipitation with a pH lower than 5.6 is considered what?

Answer 2

Acid rain or snow.

Question 3

As the acidity increases, the diversity of plants and animals that live in this water what?

Answer 3

Diversity decreases.

Question 4

Most fish disappear if the water’s pH falls to what?

Answer 4

4.5

Question 5

Acidic deposition is a major problem wherever the soil and water lack what?

Answer 5

Natural bases to neutralize acidic precipitation.

Question 6

The Canadian Shield in northern and eastern Canada is an example of an affected area by what? The thin soils and the chemical composition of the rocks there are not able to what? As a result, what have been damaged?

Answer 6

Doesn’t have enough natural bases to neutralize acidic precipitation. Naturalize the acid. So forests and lakes have been damaged.

Question 7

In areas where acid precipitation is a problem, acidic deposits build up in the what?

Answer 7

Ice and snow in the winter.

Question 8

In spring, when they ice and snow melt, the acid melt water flows into where? This quickly creates a concentration of acid that can dramatically lower the pH of the water in a pond, slough, lake, or river for a short period of time. This is known as what?

Answer 8

Aquatic systems. Spring acid shock

Question 9

Spring acid shock can seriously affect what?

Answer 9

The eggs of aquatic organisms, as well as the young offspring of spring-spawning fish.
