Australia geological structure and terrain
The entire continent of Australia is located in the southern half of the Earth and thus apart from
the rest of the continent and extends between the Departments of astronomical purpose of 1044 C and longitudes 112-153 St., and Australia, the largest island in the world, a continent
coherent
Occupies an area of dry of 7682300 km2, equivalent to three-quarters of the continent of
Europe, and as far as the United States armed and maximum extension of it from north to south
.is 3134 km from east to west 3782 km
And the continent of Australia from less continents of the world rose as the average height of
210 m above sea level, compared with the continent of Europe, 339 m and Asia 1010 m, and the
highest mountain in the Mount Kausiko which has a height of 2230 m, there are 7% of the
continent's space only exceed a height of 650 m, and all this logic is located in the eastern
coastal authorities of the continent and in spite of the equator recipe which is characterized by
.the surface of the continent, but it can be divided into the following sections terrain
First: - Eastern Highlands
Consists of a group of mountain ranges extends for a distance of 3000 km from the far north of
the continent at the semi York Peninsula to the south until the island Tzma Nia and along the
east coast and this series go, but some narrow valleys and mountain trails Olney has become a
major role later in D and the development of transport routes such as Kaschles Gateway and
.corridor Lake George gate Kelemor
These mountains takes to rise as we head south, it will be in the form of small hills of low-rise in
the north and begin the sudden rise after city Bersbon south, and be more Tdharsa and
complex, and a rise in the state of New South Wales and the state of Victoria, where the highest
.mountain peaks there (Mount Kausiko) of height 1220
Appear on these mountains the first geological time configurations where schist rocks, in
addition to some volcanic peaks as in Atherton Plateau in the state of Queensland, and the
emergence of rock and sand in the Blue Mountain West Sydney City. And disappear mountain
ranges in the Bass Strait south to appear again in Tasmania to represent a natural extension of
.her and the eastern parts
The valleys of ice time in the island's southern border these mountains, and the island of
Tasmania is the only of the land of the continent that have been ice creep due to run from the
equator and near the Antarctic Circle its extreme, as shown on the surface raised the erosion
.such as islands and fjords outstanding, lakes and valleys
Geologic formation is considered to be relatively stable mountains because they are old block
exposed to the movement of the cat-ray old and solid rocks resisted ground Gat in subsequent
times, but that erosion has long led to erosion and destroy these mountains and convert them
to the land of plain flat in some areas, but these movements renewed activity in the third
.geological time and led to the adjournment of the majority while on the move
Descend the eastern slopes of these mountains strongly toward the Pacific Ocean and gradually
towards the interior of the continent and penetrate a group of fast-flowing short rivers to the
east toward the Pacific, like Clarence River, Rigmond, Tuer and River Brsan, and formed these
rivers when estuaries plains coastal narrow become important centers of stability in the east
. coast
Second: - Central Plains
Located between the eastern highlands to the east and the western plateau to the west and the
Gulf of Carpentaria in the north to the mouth of Mary Darling River. It is a wide plains do not cut
it any manifestations or mountainous plateau and not more than higher altitude regions about
150 m above sea level, is considered the southern part of the plains below, up from the
.northern parts
Easy consists of three parts, the north of which the Supreme surrounds the Gulf of Carpentaria
and descended toward him gradually imperceptible collection of short rivers that flow in the
summer rainy season and place in it, and the middle part of it is low, especially the part that
operated Airey Lake drops 23:00 sea level this area occupies the heart of the Great Artesian
.basin which is stored in sedimentary rock compositions huge amounts of ancient groundwater
In the southern part of the plains Mary Darling Basin, which includes the most important river
system in the continent area shows a river of the same name and a length of about 2500 km,
and the region was formed in the third geological time is a modern sedimentary formations
,campaign rivers of the eastern highlands
Central Plains have been to sea immersion and the decline of sea water several times, because
its composition to the Cretaceous and formed by marine immersion huge layers of sedimentary
formations' and after sea water receding exposed rock layers to the process of lifting in some
areas and lift and landing in the middle of the pelvis and filled in the aftermath pelvic areas
configurations third modern geological time, as each Central Lowland region from north to
south was a arms of the ocean filled Balarsabat lifted later. And shows the impact of sediment
through porous sedimentary rock layers that are important huge groundwater reservoir that
leaked in the rain Ages or rainwater, which is stored in the vicinity of the Earth's surface rock
.layers
Third: - Western Plateau
Western Plateau include the western half of the continent, and is made up of very old rocks as it
is part of the old Jendonaland block, due in formations to before they Alcambere Laminate
wounds and metamorphic rocks. Plateau was exposed to sea immersion at all except for the
.northern parts of the West at the end of the first time
It was a high plateau more than it is now, but the erosion for a long period of time led to a
.reduction of height, which ranges between 200-600 m above sea level
Characterized plateau Baltarj and a blanket of soil Allattrayt especially in the northern part of
them, either in the middle section Valtkoinat gravel and sand are dominant, which is generally
of a flat surface, while the highlands are rare and far apart from each other as the McDonald
Heights and the mountains of Maskrev which has a height of 1585 m cut plateau toward the
west-east, in addition to that there are other Heights Comertfat Hammersla, which was the level
of the ancient plateau, which formed in ancient geological eras, but formed by erosion that led
to the carving surrounding rock these mountains, but the rocks of these mountains are more
.resistant to erosion from areas where its neighboring I stayed at the height of the province
The basic diversity that appears in the terrain appearances in the southwestern part where the
juxtaposition of the edges of the plateau coastal plains around the city of Perth (the capital of
the state of Western Australia), and these mountains sandwiched between Darling Heights and
the coastline and neighboring areas. This stretch plains to become more extensive in the
southern parts of the continent, represented by the Nullarbor plains bordering the Great
.Australian Bight
Covering the plateau regions sometimes sandy configurations as in the desert Gibson addition to
solid configurations interspersed with sand in the desert as Victoria, Western Plateau and
represents an important area of mineral wealth as contain a lot of minerals such as gold, lead,
.. silver, copper, aluminum
