Part 3: Sphere Interaction Cycle
Trace the cycle described in paragraph 6.
Paragraph 6 describes how water moves through all four spheres in a continuous, connected sequence. Summarize what happens at each stage of the cycle:
Step 1: Atmosphere → Geosphere Precipitation
What does water vapor become, and where does it fall?
Step 2: Geosphere → Hydrosphere Water Bodies
Where does soaked groundwater collect or flow?
Step 3: Hydrosphere → Biosphere Plant Uptake
How do living plants use this water?
Step 4: Biosphere → Atmosphere Return Cycle
What do plants release back into the atmosphere?
7
Connected System: According to paragraph 6, why does viewing Earth as one connected system help scientists explain changes on our planet?
