Carbon Cycle and Greenhouse Gas

What is the impact of fossil fuel combustion on the carbon cycle?

• Fossil fuel combustion disrupts the carbon cycle by releasing stored carbon into the atmosphere.

• Fossil fuel combustion reduces greenhouse gas emissions

• Fossil fuel combustion increases carbon sequestration in the oceans

• Fossil fuel combustion has no impact on the carbon cycle

Explain the process of carbon cycle in the environment.

• Carbon cycle is a one-way process with no recycling of carbon.

• Carbon is exchanged between the atmosphere, oceans, soil, and living organisms.

• The carbon cycle involves only the exchange of carbon between plants and animals.

• Carbon cycle is not influenced by human activities.

Which gases are considered greenhouse gases?

• Oxygen (O2)

• Nitrogen (N2)

• Carbon dioxide (CO2),

• Hydrogen (H2)

How does the burning of fossil fuels contribute to the increase in greenhouse gases?

• Burning fossil fuels reduces the amount of greenhouse gases in the environment.

• Burning fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere.

• Burning fossil fuels has no impact on greenhouse gas levels.

• Burning fossil fuels absorbs greenhouse gases from the atmosphere.

What role do plants play in the carbon cycle?

• Plants release carbon dioxide during photosynthesis

• Plants absorb carbon dioxide during photosynthesis and store carbon in their tissues.

• Plants absorb oxygen and release carbon dioxide

• Plants have no impact on the carbon cycle

Why is carbon dioxide often referred to as a greenhouse gas?

• It reflects heat away from Earth

• It traps heat in the Earth's atmosphere.

• It causes cooling of the atmosphere

• It absorbs sunlight

What are some human activities that disrupt the natural carbon cycle?

• Reducing waste production

• Burning fossil fuels, deforestation, and industrial processes

• Planting trees

• Using renewable energy sources

How do oceans play a role in the carbon cycle?

• Oceans absorb carbon dioxide from the atmosphere and store it.

• Oceans have no impact on the carbon cycle

• Oceans convert carbon into nitrogen

• Oceans release carbon dioxide into the atmosphere

What are the consequences of an imbalance in greenhouse gases in the atmosphere?

• Consequences include global warming, climate change, sea level rise, extreme weather events, and disruption of ecosystems.

• Stabilization of global temperatures

• Decrease in air pollution

• Increase in biodiversity

Explain how deforestation impacts the carbon cycle and greenhouse gas emissions.

• Deforestation reduces greenhouse gas emissions

• Deforestation has no impact on the carbon cycle

• Deforestation impacts the carbon cycle by reducing the number of trees available to absorb carbon dioxide.

• Deforestation leads to increased oxygen levels in the atmosphere
