Carbons role in fire, weathering & vulcanism Quiz (3)

What role does carbon play in the process of combustion?

• Carbon acts as a catalyst in combustion.

• Carbon is a fuel that burns to release energy.

• Carbon absorbs energy during combustion.

• Carbon prevents combustion from occurring.

Which of the following is a product of carbon combustion?

How does carbon contribute to the weathering of rocks?

• Carbon forms a protective layer on rocks.

• Carbon reacts with water to form carbonic acid, which weathers rocks.

• Carbon prevents rocks from weathering.

• Carbon increases the hardness of rocks.

What is the role of carbon in the carbon cycle during weathering?

• Carbon is permanently removed from the atmosphere.

• Carbon is released into the atmosphere as a gas.

• Carbon is stored in rocks and soil.

• Carbon is converted into oxygen.

Which gas is released during volcanic eruptions that contains carbon?

How does carbon dioxide from volcanic eruptions affect the atmosphere?

• It decreases the atmospheric temperature.

• It increases the atmospheric temperature.

• It has no effect on the atmosphere.

• It converts into oxygen.

What is the impact of fire on the carbon cycle?

• Fire decreases the amount of carbon in the atmosphere.

• Fire releases stored carbon into the atmosphere.

• Fire converts carbon into water.

• Fire prevents carbon from entering the atmosphere.

Which of the following processes is responsible for the release of carbon during a fire?

• Photosynthesis

• Combustion

• Respiration

• Evaporation

What is the primary form of carbon released during the combustion of fossil fuels?

• Carbon monoxide (CO)

How does carbonic acid contribute to the weathering of limestone?

• It strengthens the limestone.

• It dissolves the limestone.

• It converts limestone into granite.

• It has no effect on limestone.
