Down to Earth: palaeotraveller
Travel back in time and see how the Australian continent has changed. For example, find out when glaciers were common on the Australian mainland. Look at maps, landscapes, living things and environments over the last 545 million years. Compare past temperatures and sea levels with those of today. Explore which forces are changing the Earth’s surface. This learning object is one in a series of three objects.

Tectonics investigator
Investigate the internal structure of the Earth using earthquake measurements. Examine the Earth’s outer layer. Fit the Earth's tectonic plates together like a jigsaw puzzle. Identify how plate movements produce many features of the Earth’s surface. Predict the formation of new volcanic islands. This learning object is a combination of three objects in the same series.

Tectonic boundaries
Apply different tectonic forces to plate boundaries. Compare the effects when plates collide, separate, or slide past each other. Investigate the causes of earthquakes, tsunamis and volcanoes. Investigate important boundary sites, for example the Mid-Atlantic Ridge, the Andes, the San Andreas Fault, the Himalayas, and the Tonga-Kermadec Trench. Predict the geological events occurring at plate boundaries at different locations on Earth. This learning object is a combination of four objects in the same series.

Tectonics investigator: plate movement: assessment
Test your understanding of tectonic plate movement. Use animations and images to help you answer a series of questions dealing with evidence of plate movement. Interpret data from magnetic surveys of divergent zones, as well as patterns derived from hotspot traces. View and print a report on your work. This assessment object is one in a series of two objects.

Breakup of Gondwana
This is a colour clip showing a two-dimensional animation of how Australia was affected by the breakup of the supercontinent Gondwana. The clip begins 360 million years ago when Australia was joined to Antarctica, India, Africa and South America. The animation shows ice spreading across Gondwana, India breaking away, then Australia breaking away from Antarctica. The clip shows figures in millions of years ago indicating when scientists think the separations occurred. The swirling shown at the beginning of the sequence is for visual effect only and does not represent actual motion of the land masses.

Separation of Australia and Antarctica
This clip shows an animated model of Australia and New Zealand breaking away from Antarctica in the final stages of the break-up of Gondwana. The animation spans the 100-million-year interval from about 130 to about 30 million years ago. A CSIRO scientist explains how the animated model was developed and, over footage of a mountain range and a close up of the Earth's rocky crust, the narrator explains the break-up of Gondwana and what happened to Australia's inland sea.

Down to Earth: rock back in time
Choose a rock sample and find out how it was formed millions of years ago. For example, see how coal was formed in a swampy forest. Explore the Earth’s surface at the time when the rock formed. Look at maps, landscapes, living things and environments. Compare temperatures and sea levels with those of today. Explore how geological forces are changing the Earth’s surface. This learning object is one in a series of three objects.

Shaping the land
Experiment with cross-section models of the Earth's crust. Explore how landforms are shaped over time. Apply geological forces: deposition of sediments, folding, faulting, igneous intrusions and erosion. Work out a sequence of geological events to match example landforms, including real landscapes. This learning object is a combination of three objects in the same series.
