Geomorphology[ edit ] Hyden Rock, of which Wave Rock is part, consists of 2. The central and western domes are separated by a deep valley, which is now occupied by a reservoir. The central and eastern domes are linked by a low platform.

A multistage process of landform development created these domes. The initial step in the development of Hyden Rock was the subsurface alteration by weathering of granite bedrock beneath a lateritised land surface during the Cretaceous Period between — million years ago.

Depending on the degree to which it was fractured by jointingthe granite bedrock underlying this surface was altered to varying depths beneath the land surface. This process formed underground "domes" of solid granite bedrock surrounded by deeply weathered, relatively loose, and disaggregated granite.

Following separation of Australia and Antarctica and accompanying tilting of what became southwestern Australia, periodic erosion of the deeply weathered granite, which underlaid the surrounding land surface, exposed these buried solid bedrock domes over time as Hyden Rock.

A flared slope is a concave-upward or -inward bedrock surface that is typically found around the base of inselbergs, bornhardtsand granitic boulders and also on their higher slopes. Flared slopes like Wave Rock are particularly well developed in granitic landforms of south-western and southern Australia.

The flared slopes are argued to have formed by the concentrated chemical weathering around the base of an inselberg by groundwater. The chemical weathering of the bedrock by groundwater produces a concave-upward or —inward pocket of deeply weathered, relatively loose, and disaggregated bedrock within the formerly solid bedrock base of an inselberg.

When the land surface, which is underlain by deeply weathered bedrock, around an inselberg is lowered by erosion, the pocket of deeply weathered disaggregated bedrock is also removed to produce a flared slope such as Wave Rock.

It has also been argued that flared slopes can form during erosion of slopes of inselbergs.

Amazing antarctic animals include the emperor penguin, which survives the harshest winters on earth. There are also fish, birds, seals, squid, krill and whales.

Bird watching and wildlife breaks in the Cairngorms and Speyside. Located in the Cairngorms, one of the most beautiful regions of the Scottish Highlands, the Bird Watching and Wildlife Club is ideally placed to provide truly outstanding wildlife breaks.

Jul 10,  · Five major krill fishing firms Tuesday agreed to halt operations across huge swathes of the Antarctic to help protect wildlife in a move hailed as "bold and progressive" by conservationists. Now. Freshwater Habitats. Freshwater habitats include bogs, ponds, lakes, rivers and streams.

About 3% of Earth's water is freshwater, but this includes the water locked up in the ice caps and trapped. Wave Rock is a natural rock formation that is shaped like a tall breaking ocean attheheels.com "wave" is about 15 m (49 ft) high and around m ( ft) long.

It forms the north side of a solitary hill, which is known as "Hyden Rock".
