Carbon Cycle and Ocean Interactions

This video tutorial guides students through completing a carbon cycle lab sheet. It explains how to create two different carbon cycle paths, each with seven spots, starting from atmospheric CO2. The tutorial covers the movement of carbon through various paths, including oceanic CO2 and interactions with marine life. It also discusses the implications of ocean warming on carbon absorption. The video concludes with an explanation of different spheres in the carbon cycle and provides instructions for completing the lab sheet and preparing for the next class.

What is the main task in the carbon cycle gizmo lab?

• To analyze the growth of land plants

• To develop two different carbon cycle paths

• To measure the temperature of the ocean

• To create a model of the water cycle

Where do both carbon cycle paths begin?

• At atmospheric CO2

• In the ocean

• In land plants

• In marine animals

What happens to carbon dioxide when it reaches the ocean?

• It is absorbed by land plants

• It evaporates into the atmosphere

• It forms new land masses

• It dissolves in cold ocean surface waters

Why is it problematic if the oceans warm up?

• Warmer oceans increase land plant growth

• Warmer oceans dissolve less CO2

• Warmer oceans dissolve more CO2

• Warmer oceans decrease atmospheric CO2

What is one possible path for carbon after it is dissolved in the ocean?

• It becomes part of land plants

• It forms new oceanic rocks

• It evaporates back into the atmosphere

• It is used by marine animals for shells

Which sphere is associated with atmospheric CO2?

• Lithosphere

• Atmosphere

• Hydrosphere

• Biosphere

What sphere do shells and coral belong to in the carbon cycle?

• Biosphere

• Hydrosphere

• Atmosphere

• Lithosphere

What should students do after completing the lab sheet?

• Mail it to the teacher

• Discard it

• Tape it into their ISN

• Submit it online

What is the purpose of the link provided below the video?

• To review the four main spheres
