  1. 01

    Earth systems and scientific modeling

    • Use systems, feedback loops, reservoirs, and flows.
    • Read maps, graphs, satellite data, and field observations.

    Practice: Build a systems diagram for one Earth process with inputs, outputs, and feedbacks.

  2. 02

    Minerals, rocks, and plate tectonics

    • Classify rocks and minerals.
    • Explain plate boundaries, earthquakes, volcanoes, and mountain building.

    Practice: Use a tectonic map to predict hazards and justify the prediction.

  3. 03

    Weather and atmosphere

    • Use air pressure, fronts, humidity, wind, and storms.
    • Interpret weather maps and forecasts.

    Practice: Analyze a weather map and write a 24-hour forecast with evidence.

  4. 04

    Climate and climate change

    • Distinguish weather from climate.
    • Use greenhouse effect, carbon cycle, proxies, and model evidence.

    Practice: Explain one climate data graph with trend, variability, and uncertainty.
