Earth's Four Main Systems
Read the field notes
After a snowfall, the three explorers notice clouds moving overhead. Snow rests on rocks and soil. Sunlight melts some snow, and meltwater flows into a pond. A bird flies above the pond and drinks from it, while tiny plants remain beneath the snow. Each observation can involve one or more Earth systems.
Name the systems
Use these four system names in your answers: atmosphere (gases around Earth), biosphere (living things), geosphere (solid Earth, including rocks and soil), and hydrosphere (Earth's water, including ice).
