Earth and Environmental ScienceQ&A by dot point
A short Q&A bank for every NSW Earth and Environmental Science syllabus dot point. Each question and answer is drawn directly from our worked dot-point page, so you can scan key concepts before opening the long-form answer.
Module 5: Earth's Processes
- Investigate how internal and external sources of energy drive the movement of matter through Earth's interacting spheres, including but not limited to radiogenic heat, solar radiation and convection in the Australian context6Q&A pairs
- Investigate the processes that concentrate metals and minerals into economic ore deposits, including but not limited to magmatic, hydrothermal, sedimentary and weathering processes that operate in the Australian geological setting3Q&A pairs
- Analyse how relative and absolute dating methods, and the fossil record, are used to construct the geological time scale and to interpret past environments, including Australian examples such as the Ediacaran fauna and the Riversleigh deposits5Q&A pairs
- Investigate how minerals form by crystallisation and how their physical and chemical properties, including crystal structure, hardness, cleavage and composition, are used to identify them in the Australian context4Q&A pairs
- Analyse the lines of evidence for continental drift and sea-floor spreading that led to the theory of plate tectonics, including but not limited to palaeomagnetism, fossil and rock matches and the Australian geological record5Q&A pairs
- Investigate the rock cycle, including but not limited to the formation of igneous, sedimentary and metamorphic rocks and the processes that transform one rock type into another in the Australian context5Q&A pairs
- Investigate the physical, chemical and biological processes of weathering and erosion, and how they interact with climate and organisms to form soils, in the Australian context5Q&A pairs
Module 6: Hazards
- Investigate how plate boundary processes produce earthquakes, including but not limited to the mechanisms of seismic waves, the measurement of magnitude and intensity, and the assessment of earthquake hazard in the Australian context5Q&A pairs
