AC9S8U04
Earth and space sciences
describe the key processes of the rock cycle, including the timescales over which they occur, and examine how the properties of sedimentary, igneous and metamorphic rocks reflect their formation and influence their use
Elaborations
- AC9S8U04_E1comparing the observable properties of different types of rocks and identifying them using a provided dichotomous key
- AC9S8U04_E2exploring 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
- AC9S8U04_E3analysing 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
- AC9S8U04_E4examining fossil evidence, such as body, trace or opalised fossils, to predict how and when a rock was formed
- AC9S8U04_E5explaining the uses of different types of rocks with reference to their properties and formation
- AC9S8U04_E6exploring the traditional geological knowledges of First Nations Australians that are used in the selection of different rock types for different purposes
- AC9S8U04_E7investigating 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
- AC9S8U04_E8exploring how the mining of ores and minerals impacts on local environments and examining environmental rehabilitation initiatives
