Elaborations
- • Elaboration comparing the observable properties of different types of rocks and identifying them using a provided dichotomous key
- • Elaboration exploring the major processes of the rock cycle including weathering, erosion, deposition, melting, crystallisation, uplift, heat and pressure in the formation of different types of rocks
- • Elaboration analysing the role of forces and heat energy in the formation of different types of rocks and comparing how quickly or slowly different processes can occur
- • Elaboration examining fossil evidence, such as body, trace or opalised fossils, to predict how and when a rock was formed
- • Elaboration explaining the uses of different types of rocks with reference to their properties and formation
- • Elaboration exploring the traditional geological knowledges of First Nations Australians that are used in the selection of different rock types for different purposes
- • Elaboration investigating how First Nations Australians have used quarrying to access rocks for use as or production of everyday objects such as grindstones, hammerstones, anvils and cutting tools
