Earth's Hydrosphere and the Water Cycle

Explain how solar thermal energy and gravity drive the continuous movement and state changes of water through Earth's systems.

Examine Earth's layered internal structure, plate tectonic movements, and the geological processes that build and reshape surface landforms.

Analyze ocean topography, water density, global circulation patterns, and how gravitational forces produce tides.

Describe atmospheric structure, air pressure dynamics, and how interacting air masses generate predictable weather systems.

Analyze observational data to explain predictable astronomical cycles including day and night, seasonal variations, and lunar phases.

Compare the physical properties, scales, and orbits of planets and explain how gravity governs mass, weight, and planetary motions.

Analyze threats to Earth's atmosphere and systems, and investigate sustainable community architecture, renewable energy, and resource stewardship.
