Physical geography Geology The Sydney region includes coastal features of cliffs, beaches, estuaries and deep river valleys known as rias. Narrabeen Group of sedimentary rocks at Narrabeen. Sydney sprawls over two major regions: Erosion by coastal streams has created a landscape of deep canyons and remnant plateaus.

The rising sea level between 18, and 6, years ago flooded the rias to form estuaries and deep harbours. The city has fault lines which run considerably deep beneath the Sydney basin, dating back to when New Zealand started breaking away from Australia more than 85 million years ago.

To the east the basin continues to the edge of the continental shelf.

In the Sydney sandstone, the ripple marks from the ancient river that brought the grains of sand are distinctive and easily seen, telling geologists that the sand comes from rocks formed between to million years ago far to the south. This means that the highest part of the visible lines almost always faces approximately south.

There are volcanic rocks from low hills in the shale landscapes. At a time in the past, monocline formed to the west of Sydney. The monocline is a sloping bend that raises the sandstone well above where it is expected to be seen, and this is why the whole of the visible top of the Blue Mountains is made of sandstone.

Sandstone slopes in the Sydney area are on three sides: The Cumberland Plain is a low-lying area largely over shale and labile sandstone which derives its recognition largely by comparison with the surrounding uplands of harder quartzose, the Hawkesbury Sandstone. Relative to the surrounding higher sandstone lands Hornsby and Blue Mountains Plateaux it was an early matter of debate in Sydney physiographic circles as to whether the Cumberland Plain had gone down, or the surrounding plateaux had been raised up.

Prospect Hill in western Sydney is the largest assemblage of igneous rock in Sydney. Slow erosion of the overlying layers of sedimentary rock by the flow of rainwater have eventually laid bare the edges of the volcanic and metamorphic rocks of the intrusion.

The Gap, an ocean cliff on the South Head peninsula in Watsons Baywas laid as sediment more than million years ago in the Triassic period. During the Jurassic era, a cataclysmic event resulted in an enormous crack forming within the strata. The Gap itself forms a sequence that continues offshore to the edge of the Sahul Shelf.

View of Nepean River from just south of Penrith. The Nepean River rises to the south in the Woronora Plateau, and wraps around the western edge of the city. Swamps and lagoons are existent on the floodplain of the Nepean River. Broken Bay and the lower Hawkesbury form the commonly accepted boundary between Sydney and the Central Coast to the north.

The remaining section of Warragamba River flows 3. At east Parramatta the river becomes a tidal estuary that flows into Port Jacksoncommonly known as Sydney harbor. The reestablishment of foreshore mangroves has been a major focus of the ecological management of the Parramatta river and Sydney Harbor.

The other major tributary of Botany Bay is the Cooks River, running through the inner-south western suburbs of Canterbury and Tempe. The Woronora River, on the southern edge of the Sydney Plain, flows in a steep-sided valley from the Woronora Dam to the eastern estuary of the Georges River.

Sydney has a number islands in its harbour and surrounding rivers. Bare Island in Botany Bay. Scotland Island in the Northern Beaches. And Rodd Island in Parramatta River.Australia Geography The state of Tasmania includes numerous small islands and extends to Macquarie Island which lies approximately 1, km south east of the main island.
