Introduction: Earth can be divided into four systems. The gen
surface
. The hydrosphere is composed of all of Earth's water. The sensorare is the rocky,
non-living part of Earth. The buderinant consists of all living things, including people. Some
scientists use the term "anthroposphere" to describe everything made or modified by humans.
Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and
geosphere?
1. Explore: Use the Gizmo to create a path for carbon that begins and ends in the atmosphere.
Fill in the steps in the path below. Then, label each location with the system it represents.
Finally, summarize very briefly how the carbon atom got to that location.
Carbon path
Atmospheric CO2
System
Atmosphere
How it got there
Atmospheric CO2 comes from volcanoes,
burning fossil fuels, and other sources.
