Practice ordering rock layers using the four relative dating principles, or placing eras and periods on the geologic time scale, with an answer-check mode.

Practice telling weathering, erosion, and deposition apart in a described scenario, naming the specific mechanical or chemical process, the transporting agent, and the resulting landform.

Practice tracing water through evaporation, transpiration, condensation, precipitation, infiltration, and runoff, naming every process in order for a given or freshly generated pathway.

Practice reasoning through porosity versus permeability, confined versus unconfined aquifers, and cones of depression from a groundwater scenario, tied to the governing property.

Practice identifying shield, composite, and cinder cone volcanoes from their shape, eruption style, or magma viscosity, tying every classification to silica content and gas behavior.

Practice identifying Earth's internal layers by composition and by physical behavior from depth, state, or seismic-wave clues, then check answers against the exact clue.
