Down to Earth: palaeotravellerTravel 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. |

Tectonic boundariesApply 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. |

Breakup of GondwanaThis 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 AntarcticaThis 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 timeChoose 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. |

Indonesia's Mount Merapi, 2006This is a colour photograph of the peak of Mount Merapi in Central Java Province on the Indonesian island of Java. This photograph was taken on 12 June 2006 during a period of volcanic activity. It shows bright orange lava flowing down the steep slopes of this conical volcano, and clouds of hot gas and ash streaming into the atmosphere. As seen in the image, the summit of Merapi lacks vegetation. |

Whakaari (White Island), 1999This is a colour photograph of Whakaari, commonly referred to as White Island, which is located in the Bay of Plenty off the North Island of New Zealand. This aerial photograph taken in 1999 shows emissions of mostly steam and wet ash produced by a small eruption of the volcano at the time. |

Quake line near Meckering, 1968This is a black-and-white aerial photograph showing fissures left by an earthquake near the township of Meckering in Western Australia, in 1968. The fissures run through the Great Eastern Highway and through wheatfields on either side. On the highway are the figures of a group of people observing the damage, and several vehicles. |

The San Andreas Fault, CaliforniaThis is a colour aerial photograph of the San Andreas Fault in California, USA. This image shows the fault line as it dissects the Carrizo Plain grassland. The central fault line divides two tectonic plates: on the right of the fault is the Pacific plate and on the left is the North American plate. |

The Changing Face of Australia, 1970: UluruThis clip shows images of the ancient sandstone monolith Uluru (previously known as Ayers Rock), located on a plain south-west of Alice Springs in the Northern Territory, during and after a rainstorm. The rain creates waterfalls that flow down the rock's surface, revealing the weathering process that has aged and shaped the rock over time. A commentary at the beginning of the clip sets the scene. As the sounds of the storm pass, light melodic music accompanies the changing images of Uluru. |

Rock formation photograph from 'Echidna', 1980This is a colour photograph of an eroded rock formation along the coastline of Australia. It shows a male figure standing on a rock platform underneath the relatively thin shell of the eroded overhang of a huge boulder. |

Natural rock arch formation, Sorrento, 1945This is a black-and-white photograph, taken on acetate film, of a natural rock arch formation at Sorrento Back Beach on the Bass Strait side of the Mornington Peninsula, Victoria. The photograph has been taken at low tide, looking through the arch of weathered rock towards the ocean. Some sparse vegetation is growing on the rock. Two people can be seen in the distance, looking into a pool of water on the beach. Behind them are lines of breakers. |

Native vegetation and the watertableThis is a colour two-dimensional animation showing how the watertable is formed and maintained. The clip shows a cross-sectional view of trees and their deep roots in the soil, and the underground water. It shows clouds moving across and the rain seeping into the ground and being absorbed by the tree roots before it can reach the watertable below. |

Causes of soil salinityThis is a colour clip showing how soil salinity and erosion result from clearing of native vegetation. It includes a two-dimensional animation of a cross-section of a few trees with deep roots in the ground, and shallow-rooted crops that have replaced many of the trees. The clip shows clouds moving across the land and dumping rainwater that seeps into the underground watertable. It shows the rising watertable bringing salt to the surface and killing plants. It also shows colour footage of severe soil erosion. |

'Around a gum tree', 1949 - asset 1This is an excerpt from a black-and-white documentary film entitled 'Around a gum tree', narrated by Wilfrid Coad Thomas. The film as a whole features different species of gum trees and their different environments with comment on aspects of Australian life, and was made under the auspices of the Shell Film Unit in 1949. The excerpt opens in a field with stacks of bagged grain and straggly Mallee gums in the background. Over close-ups of a divided gum trunk emerging from the ground, the commentary describes the Mallee gum's extended root system and its ability to hold the soil together. Belts of gums are shown on the flat, cultivated plains before the film cuts to show gum roots exposed through severe erosion. The closing scene is of dust and dead vegetation blowing across a desert as the narrator says that good land became a desolate wasteland through poor management. |

Snowy Hydro - Conservation in the Snowy Mountains, 1955: Clearing methods invite bushfireThis clip, from 1955, shows the devastating environmental effects of land clearing and grazing in the high country (subalpine and alpine regions) of the Snowy Mountains in south-eastern New South Wales and north-eastern Victoria. Over scenes of dead trees and bare hills, the narrator describes the practice of intentional burning off and grazing and how these activities have increased the risk of bushfires and contributed to soil erosion. |
