Understanding the Carbon Cycle

The video tutorial introduces a carbon cycle gizmo, explaining how carbon moves through various Earth systems such as the atmosphere, geosphere, hydrosphere, and biosphere. It guides users on how to use the gizmo to trace carbon pathways by following blue highlights. The tutorial also provides instructions for completing a worksheet and mentions a modeling tab for a future assignment.

What is the primary purpose of the Carbon Cycle Gizmo?

• To explain the chemical composition of carbon

• To show how carbon moves through Earth's systems

• To illustrate the history of carbon on Earth

• To demonstrate how carbon is created

Which Earth system does carbon NOT transition to from the atmosphere?

• Hydrosphere

• Geosphere

• Stratosphere

• Biosphere

What process allows carbon to move from the atmosphere to land plants?

• Combustion

• Respiration

• Photosynthesis

• Evaporation

When carbon dissolves in the ocean, which Earth system is it part of?

• Hydrosphere

• Geosphere

• Atmosphere

• Biosphere

What should you look for to decide the next step in the carbon pathway?

• Red arrows

• Green circles

• Blue highlights

• Yellow stars

Which of the following is NOT a pathway for carbon from the atmosphere?

• Land plants

• Space

• Exposed rocks

• Ocean

What is the purpose of the worksheet in the Carbon Cycle Gizmo?

• To trace carbon pathways and fill out transitions

• To calculate carbon emissions

• To predict future carbon cycles

• To measure carbon levels in the atmosphere

Where do you find the description of how carbon transitions between systems?

• At the top of the worksheet

• In the middle of the worksheet

• At the bottom of the worksheet

• On a separate page

What is the starting point for tracing carbon pathways in the worksheet?

• Carbon in the biosphere

• Carbon in the ocean

• Carbon in the geosphere

• Carbon dioxide in the air

What is the role of the modeling tab in the Carbon Cycle Gizmo?

• To model carbon emissions

• To be used in a different assignment

• To calculate carbon footprints

• To simulate carbon absorption
