Chapter 9.1
Earth's Water Systems and the Hydrologic Cycle
Discover how water continuously moves through Earth's oceans, atmosphere, and land through evaporation, condensation, precipitation, and more and why this cycle is essential for all life on Earth.
What You'll Learn
The hydrologic cycle moves water through atmosphere, land, and oceans.
Key processes include evaporation, condensation, precipitation, and infiltration.
Oceans hold ninety-seven percent of all water on Earth.
Glaciers and icecaps store most of Earth's available freshwater supply.
What You'll Practice
1
Students identify key hydrologic cycle processes like evaporation and transpiration.
2
Learners explain groundwater movement through aquifers and surface systems.
3
Practice questions test vocabulary including infiltration, runoff, and condensation.
Why This Matters
Understanding Earth's water systems equips students to analyze environmental challenges such as drought, flooding, and freshwater scarcity that affect communities worldwide.
