Metamorphism
https://australianmuseum.net.au/learn/minerals/shaping-earth/metamorphism/The word metamorphism comes from Greek and means 'change of form'. Metamorphic rocks are pre-existing rocks whose mineral composition and/or texture has been changed by processes within the Earth.

The Sydney Basin
https://australianmuseum.net.au/learn/minerals/shaping-earth/the-sydney-basin/The Sydney Basin is a major structural basin containing a thick Permian-Triassic (290 Ma - 200 Ma (million years old)) sedimentary sequence that is part of the much larger Sydney-Gunnedah-Bowen Basin.

Metamorphic rocks
https://australianmuseum.net.au/learn/minerals/shaping-earth/metamorphic-rocks/Metamorphic rocks form because of changes in temperature and depth of burial within the Earth in a solid state without actual melting.
-
Types of metamorphism
https://australianmuseum.net.au/learn/minerals/shaping-earth/types-of-metamorphism/There are several different types of metamorphism, including dynamic, contact, regional, and retrogressive metamorphism, that form and shape rocks.

Water and sedimentary transport
https://australianmuseum.net.au/learn/minerals/shaping-earth/water-and-sedimentary-processes/Water plays a vital role in most sedimentary processes. Pure water itself has little effect on rocks. It is the dissolved gases in water, particularly carbon dioxide, that cause the chemical decay of minerals and mineral dissolution.
-
Crystallography
https://australianmuseum.net.au/learn/minerals/what-are-minerals/crystallography/Minerals can be identified by the shape of their crystals: called crystallography. External crystallography measures the outside properties of crystals such as length of crystal surfaces and the angles between these surfaces.

Plate Tectonics
https://australianmuseum.net.au/learn/minerals/shaping-earth/plate-tectonic-processes/Since the 1950s, several discoveries have led to a new understanding of how the Earth works.

Meteors and Meteorites
https://australianmuseum.net.au/learn/minerals/shaping-earth/meteors-and-meteorites/Solid pieces of extraterrestrial debris (meteoroids) can stray from their orbits in outer space and be captured by Earth's gravity.

Looking inside the Earth
https://australianmuseum.net.au/learn/minerals/shaping-earth/looking-inside-the-earth/The internal structure of the Earth consists of three main parts, the crust, mantle and core. The division between the crust and the mantle is called the Moho.

Sedimentary processes
https://australianmuseum.net.au/learn/minerals/shaping-earth/sedimentary-processes/Sediments are formed by the breakdown (both physical and chemical) of pre-existing rocks, which may be of igneous, metamorphic or sedimentary origin.
