Abiotic Factor Measurement
Techniques for measuring non-living environmental variables such as temperature, light, pH, moisture, wind speed, and dissolved oxygen.
Real World
During the 2019 Australian bushfires, automated weather station networks recorded soil moisture dropping to record lows months before ignition, allowing scientists to map fire risk using abiotic data alone.
Exam Focus
Always state the specific instrument used to measure each abiotic factor — writing 'a probe' instead of 'oxygen probe' or 'pH meter' loses precision marks.
