Sedimentary, igneous and metamorphic rocks contain minerals and are formed by processes that occur within Earth over a variety of timescales (ACSSU153)

Elaborations
  • representing the stages in the formation of igneous, metamorphic and sedimentary rocks, including indications of timescales involved
  • identifying a range of common rock types using a key based on observable physical and chemical properties
  • recognising that rocks are a collection of different minerals
  • considering the role of forces and energy in the formation of different types of rocks and minerals
  • recognising that some rocks and minerals, such as ores, provide valuable resources

How metamorphic rocks are formed

Imagine the forces required to change one type of rock into another type. Listen to presenter, Bernie Hobbs, explain the forces that transform sedimentary rocks to metamorphic rocks. She visits the Australian Nuclear Science and Technology Organisation (ANSTO) to demonstrate how limestone can be transformed into its matching ...

Oil from super-greenhouse events

Why did most of the world's oil deposits form at a specific prehistoric time? Learn how overheated super-greenhouse climates caused vast stretches of the world's oceans to stagnate and become depleted of oxygen. Discover the connection between these anoxic events and Earth's oil reserves. Watch scientists investigating ...

Erosion moves rocks and soil

Imagine the power of wind and water as mountains are worn down and sent to the sea. Recognise the importance of water as it moves particles of different sizes and deposits them to form new soils that support plant and animal life. Consider evidence that erosion is an important process in the formation of new rock in a continual ...

The rock cycle: Connected Learning Experience

This online resource is a Connected Learning Experience (CLE) explore the rock cycle.In this investigation, students explore the processes in the rock cycle that result in new rocks being formed. Through hands-on investigation, they learn about the formation and properties of the different types of rocks.

Video

Rock recipes

Explore the different types of minerals inside rocks. See that most rock-forming minerals are made up of just two common elements. Discover that most minerals are made up of the same basic building blocks put together in different ways, and that this can explain some of their properties.

Diprotodon: fossils and extinction

When did Diprotodon die out? To answer this question, teams of scientists and volunteers are working together to excavate Diprotodon bones and study the landscape where they're found. Go on the road with Catalyst to the 'badlands' of South Australia and investigate the evidence behind Diprotodon extinction.
