Question

1. describe at least two ways that carbon enters the atmosphere.
2. how are fossil fuels created? soil is transformed over time into peat and then into coal.
3. how are the oceans involved in the carbon cycle?
4. track a carbon atom through the carbon cycle. please make the color of your arrows red. drag and drop the labels and draw in arrows to represent your journey.

Explanation:

1. Carbon enters the atmosphere through processes like respiration (organisms exhaling carbon - dioxide) and the burning of fossil fuels.
2. Fossil fuels are created from the remains of ancient plants and animals that were buried and subjected to high pressure and temperature over millions of years.
3. Oceans are involved in the carbon cycle through processes such as the dissolution of carbon - dioxide from the atmosphere into the ocean water and the release of carbon - dioxide back into the atmosphere through processes like oceanic outgassing.

Answer:

1. Respiration (organisms release CO₂) and burning of fossil fuels (coal, oil, gas release CO₂).
2. From the remains of ancient plants and animals buried under high pressure and temperature over long time - scales.
3. Oceans dissolve CO₂ from the atmosphere and also release it back through outgassing.
