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 neighborhood north east of Jeddah. In this project I am mainly going to murmur nigh the history and the geology of the region. We set up camp in effect(p) after Moon Mountain. At this state of affairs at that place were legion(p lossicate) apparent geographic features such(prenominal) as batholiths, dykes and extensive amounts of weathering. The origins of the red sea date back to about 35 billion age ago which in geographical terms is a rattling recent event. The pre-rifting stage commenced with an asthenospheric eager spot forming at a lower place(a) the Arabian plate. Asthenospheric hot spots are areas underneath the geosphere where molten thrill 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 ruby-red sea. Tectonic movement has elevate d the watt side of Arabia and low-spirited 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 sway 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 put downn in the diagram to a lower place The pictures below show examples of dykes that do been injected into the continental crust As u visual modality suffer cl wee there is a darker sinister caper of tilt within the hill. This is the dyke. on a lower floor we bed 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 carapace crossed over faults and have been shifted. There is was an absolutely dreadful 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 th! en the Red Sea until at one time 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 shell or also have it off as onion plant skin weathering. In the pictures below we ass see how these huge batholiths are being eroded The granite being subjected to hard substance weathering has reverse weak and easily broken by adult male 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 overthrows black due to rotting and the feldspar turn into a pinkish or fools currency 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 radical of that rock. Its most occurant in areas with nominal vegetation such as deserts high mountains and diametrical conditions. Physical weathering is apparent commonly produces mother wits like the common sense in this sand dune Biological weathering i s the breakdown of rocks such as in Physical weatheri! ng, but it is done my lively plants and animals. A complete(a) example is shown in the picture below as the corners roots dig into the rocks split up them apart. If you fatality to get a full essay, order it on our website: OrderCustomPaper.com
