- What is meant by “Geosphere” in this lesson?Earth’s spheres
- The geosphere includes Earth's solid rocks, sediments, and interior.
- What is meant by “Hydrosphere” in this lesson?Earth’s spheres
- The hydrosphere includes Earth's liquid water, groundwater, and frozen water.
- What is meant by “Atmosphere” in this lesson?Earth’s spheres
- The atmosphere is the envelope of gases surrounding Earth.
- What is meant by “Biosphere” in this lesson?Earth’s spheres
- The biosphere includes living organisms and the regions they inhabit.
- What is meant by “Cryosphere” in this lesson?Earth’s spheres
- The cryosphere is the frozen-water portion of the Earth system.
- What is meant by “System boundary” in this lesson?Earth’s spheres
- A boundary defines which components are included in the system being studied.
- What is meant by “Reservoir” in this lesson?Cycles and interactions
- A reservoir stores material within an Earth-system cycle.
- What is meant by “Flux” in this lesson?Cycles and interactions
- A flux is a rate of transfer between reservoirs.
- What is meant by “Water cycling” in this lesson?Cycles and interactions
- Water moves among reservoirs through processes including evaporation, condensation, precipitation, and runoff.
- What is meant by “Carbon cycling” in this lesson?Cycles and interactions
- Carbon moves among air, organisms, oceans, and rocks through biological and geological processes.
- What is meant by “Feedback” in this lesson?Cycles and interactions
- A feedback occurs when a change produces effects that influence the original change.
- What is meant by “Energy flow” in this lesson?Cycles and interactions
- Energy enters, transfers through, and leaves Earth systems rather than recycling identically to matter.
- What is meant by “Measurement unit” in this lesson?Reading Earth science data
- A unit specifies the quantity scale needed to interpret a measurement.
- What is meant by “Time series” in this lesson?Reading Earth science data
- A time series orders measurements by observation time.
- What is meant by “Spatial pattern” in this lesson?Reading Earth science data
- A spatial pattern describes how a measured property varies across locations.
- What is meant by “Anomaly” in this lesson?Reading Earth science data
- An anomaly is a difference from a specified reference value or baseline.
- What is meant by “Uncertainty” in this lesson?Reading Earth science data
- Uncertainty describes limits to the precision or confidence of an estimate.
- What is meant by “Correlation” in this lesson?Reading Earth science data
- Correlation describes association and does not by itself establish a causal mechanism.
