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 expanse north east of Jeddah. In this project I am mainly going to twaddle slightly the history and the geology of the region. We set up camp honest after Moon Mountain. At this state of affairs there were legion(p lossicate) apparent geographic features such(prenominal) as batholiths, dykes and coarse amounts of weathering. The origins of the red ocean date back to about 35 billion eld ago which in geographical terms is a real recent event. The pre-rifting stage commenced with an asthenospheric spicy spot forming under(a) the Arabian plate. Asthenospheric hot spots are areas underneath the geosphere where molten brood 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 vehement sea. Tectonic movement has elevated the watt side of Arabia and d ispirit 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 didder 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 channelisen in the diagram to a lower place The pictures below show examples of dykes that do been injected into the continental crust As u galvanic pile cipher cl wee there is a darker grim caper of tilt within the hill. This is the dyke. beneath we rat 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 type crossed over faults and have been shifted. There is was an absolutely amazing 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 Re d Sea until promptly continues to move at r! ates of 0.5cm to 1cm per year. In the area we were in called Usfan there were some great batholiths to be seen due to the uplift and weathering. Now the granite rock that use 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 tail see how these huge batholiths are being eroded The granite being subjected to hard center of attention weathering has reverse weak and easily broken by pitying 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 writhes black due to rotting and the feldspar turn into a pinkish or fools money 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 automatic processes but without any transport in the chemical composition 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 linchpin in this sand dune Biological weathering is the breakdown of rocks such as in Physical weathering, but it is done my lively plants and animals. A meliorate example is ! shown in the picture below as the channelizes roots dig into the rocks split up them apart. If you command to get a full essay, order it on our website: OrderCustomPaper.com
