What is acid rain?

Back

Acid rain is precipitation that has a lower pH than normal rainwater, typically below 5.6, due to the presence of sulfuric and nitric acids from pollution.

Front

What pH level indicates acid precipitation?

Back

A pH level below 5.6 indicates acid precipitation.

Front

What are the primary causes of acid rain?

Back

The primary causes of acid rain are high concentrations of sulfuric and nitric acids, primarily from industrial pollution.

Front

What are the environmental impacts of acid rain?

Back

Acid rain can damage drinking water sources, aquatic life, and architecture/buildings.

Front

Where is the Ozone Layer located?

Back

The Ozone Layer is found in the stratosphere, which is the upper portion of the atmosphere.

Front

What is the role of a catalytic converter?

Back

A catalytic converter reduces harmful emissions from an internal combustion engine by converting pollutants into less harmful substances.

Front

Which gas is commonly associated with acid rain formation?

Back

Sulfur dioxide (SO2) is commonly associated with acid rain formation.

Front

What is the pH of normal rainwater?

Back

The pH of normal rainwater is typically around 5.6.

Front

How does acid rain affect aquatic ecosystems?

Back

Acid rain can lower the pH of water bodies, harming fish and other aquatic organisms.

Front

What is the significance of the stratosphere?

Back

The stratosphere contains the ozone layer, which protects life on Earth by absorbing harmful ultraviolet (UV) radiation.
