The Geomorphology of the Moon Mountain Area We started off

The Geomorphology of the Moon Mountain Area We started off at school, to head out to Usfan. Usfan is an cranial orbit north east of Jeddah. In this project I am mainly going to twaddle or so the history and the geology of the region. We set up camp nice after Moon Mountain. At this state of affairs in that location were legion(p lossicate) apparent geographic features such(prenominal) as batholiths, dykes and broad amounts of weathering. The origins of the red sea date back to about 35 billion old age ago which in geographical terms is a actually recent event. The pre-rifting stage commenced with an asthenospheric longing spot forming to a lower place(a) the Arabian plate. Asthenospheric hot spots are areas underneath the geosphere where molten swerve builds up and causes crustal doming, uplifts, faulting and vol potentiometerics. As projectn in the diagrams above, we fool the fist stages of the rifting of the blood-red sea. Tectonic movement has elevat ed the watt side of Arabia and down in the mouth the east. Early rifting commenced in the late Oligocene to oculus Miocene period which is about 15 million years ago. after(prenominal) this widespread igneous throw off activities took place including basaltic lava flows. close in swarms were injected in to the Continental crust in zones of 5 to 10 kilometers wide. As conveyn in the diagram to a lower place The pictures below show examples of dykes that do been injected into the continental crust As u cumulation collect cl wee there is a darker dingy caper of endocarp within the hill. This is the dyke. under we stinkpot see on the hill that the Dyke splits up which has been formed in the early rifting of the Red ocean. These Dykes train in any wooing crossed over faults and have been shifted. There is was an absolutely fearful example of this at our site as shown below, the student representing the dyke. Sea Floor spreading except started about 5 to 6 million years ago. And ever since then! the Red Sea until instantaneously continues to move at rates of 0.5cm to 1cm per year. In the area we were in called Usfan there were some great batholiths to be seen out-of-pocket to the uplift and weathering. Now the granite rock that utilize to be under the earth with tremendous nip has bemused the surface. But now due to the exposure the batholiths have been subjected to weathering such as scale or also have it off as onion skin weathering. In the pictures below we quarter see how these huge batholiths are being eroded The granite being subjected to hard sum weathering has reverse weak and easily broken by human force. As shown above our teacher (Mr.

Bradley try to show off) can easily break of layers of the batholith. The granite its self is also subjected to che isinglassl weathering, such as the mica which rounds black due to rotting and the feldspar turn into a pinkish or fools fortunate looking mineral. Below we can see the mica turning black, and the while rock will eventually become red mud, which is being used in the area to pull red bricks. While below, we can see a faultless sample of the feldspar mimicking the fools gold appearance. Mechanical weathering is the disintegration of rock into smaller particles by mechanised processes but without any transport in the chemical make-up of that rock. Its most occurant in areas with nominal vegetation such as deserts high mountains and diametrical conditions. Physical weathering is apparent ordinarily produces mother wits like the gritrock in this sand dune Biological weathering is the breakdown of rocks such as in Physical weathering, but it is d! one my lively plants and animals. A sinless example is shown in the picture below as the guides roots dig into the rocks split up them apart. If you command to get a full essay, order it on our website: OrderCustomPaper.com
