04.04.24 The Carbon Cycle and Greenhouse Effect Review

05.22.24 Cycle 4 Review

Multiple Choice

What is the most important factor that determines an area's climate?

• Altitude (height above sea level)

• Latitude (distance from the equator)

• Topography

• Distance from nearby waters

Open Ended

How does latitude affect an area's climate?

Open Ended

Name the 4 parts or "spheres" of the Earth and briefly describe what each of them consists of.

Multiple Choice

TRUE or FALSE?
All of the carbon in existence is continually recycled in the carbon cycle.

• True
• False

Open Ended

Describe the difference between carbon sinks and carbon sources.

Carbon Sink

• Places where Carbon is Trapped for long periods of time

• These sinks are created in places where it is hard to move carbon through that portion of the cycle

• Examples of these sinks; Coal, Peat, and Fossils/Sediment

A carbon source is anything that releases more carbon into the atmosphere than it absorbs - for example, the burning of fossil fuels or volcanic eruptions, deforestation, etc.

​

Carbon Source

Multiple Choice

Which of the following removes carbon from the atmosphere?

• Combustion
• Respiration
• Photosynthesis
• Death

Multiple Choice

Human activities add greenhouse gases to the atmosphere, therefore we are carbon ________.

• sinks

• sources

Multiple Select

Select all that apply.

Which of the following are carbon sources.

• fossil fuel combustion

• volcanic eruptions

• forests

• oceans

Combustion

Combustion is the burning of materials to release energy

The byproduct of the burning of fossil fuels (coal, oil and natural gas) is the release of carbon dioxide into the atmosphere

Releasing too much carbon dioxide increases the greenhouse effect and contributes to global warming

Carbon in the Earth/ Lithosphere

• Fossils

• Coal

• Peat

• Fuel

Carbon in Living Things/ Biosphere

• Photosynthesis

• Food Chain

• Waste

• Death

Carbon in the Atmosphere

• Respiration

• Combustion

• Factories

• Death

Multiple Select

Choose the three fossil fuels

• natural gas

• water

• coal

• hydrogen

• oil

Multiple Choice

Carbon can be found in...

• The atmosphere
• Soil
• Fossil fuels
• All of the above

Open Ended

What is an example of a carbon sink?

Open Ended

What is an example of a carbon source?

Open Ended

Is burning fossil fuels good for the environment? Why or why not?

Multiple Choice

The average temperature of the surface of Earth has increased approximately 1°C in the past century. Which reason best explains this increase in temperature?

• lower levels of ozone in the atmosphere
• lower levels of nitrogen in the atmosphere
• higher levels of carbon dioxide and other greenhouse gases in the atmosphere
• higher levels of oxygen in the atmosphere

Multiple Choice

What would happen to the Earth's average temperature if there were no greenhouse effect?

• it would get so cold nothing could survive.

• it would have no effect at all.

• the Earth would continue to warm up because of its spin.

Multiple Select

Which two greenhouse gases absorb the most heat?

• CO2

• Methane (CH4)

• Ozone (O3)

• Water Vapor (H2O)

Multiple Select

Which of the following are possible Environmental Effects of Climate Change?

**Select all that apply!

• Melting glaciers.

• More stable weather patterns.

• Changing ecosystems.

• Sea level rise.

• Increased biodiversity.

Open Ended

What are some things that we can do better to help slow down climate change?
