processes are predominant. Secondly‚ most of the tectonic plates in this region are diverging or converging. And finally‚ the volcanoes that occur in this region are as a result of stretching and thinning of the earth’s crust called ”non-hot spots”. Interplate volcanism such as the East Africa Rift which is an active narrow zone in which the African plate is in the process of splitting into two new tectonic plates called the Somali and the Habian plate. For the historical background of vulcanicity in East

Name: ******** Class: DME2 Title: Flow Measurement Date: 11/02/2013 Lecturer: Mr Higgins Summary: In this experiment many different meters were used to measure fluid flow rate; the orifice plate‚ the venture meter‚ the rota meter and the weigh tank. Each meter works by its ability to alter a certain physical property of the flowing fluid and then allows this alteration to be measured. The measured alterations are linked directly to the flow rate and these measurements are subbed in

I will discus the history of earthquakes‚ the kinds and locations of earthquakes‚ earthquake effects‚ intensity scales‚ prediction‚ and my own predictions. An earthquake can be defined as vibrations produced in the earth’s crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations can range from barely noticeable to a disastrous‚ and destructive act of nature. Six kinds of shock waves are generated

seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive‚ constructive and conservative. The pressure is suddenly released as the plates jerk past each other‚ sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the crust to become mobile which creates the different types plate margins‚ makes the cause due to physical factors. However human activity

500- to 750-word explanation regarding the role of plate tectonics in the origin of igneous rocks. The role of plate tectonics in the origin of igneous rock is extremely important. Igneous rock is formed from magma that reaches the continental and oceanic crust or through hot spots that are around the world. There are three different places where igneous rocks can form; where the lithospheric plates pull apart at mid ocean ridges‚ where plates come together at seduction zones‚ and where continental

Geo assessment Mt Etna An eruption begins when pressure on a magma chamber forces magma up through the conduit and out the volcano’s vents. When the magma chamber has been completely filled‚ the pressure in the pipe will build up very high resulting in an explosion. When magma reaches earth’s surface it is called lava. It may pour out in gentle streams called lava flows or erupt violently into the air. Rocks ripped loose from the inside of the volcano or torn apart by the gas may be shot into the

There are four major factors that often contribute to the formation of hydrothermal copper porphyry: 1) readily available mineralizing fluid solutions that dissolve and transport metals‚ 2) openings in rocks which allow permeable flow of hydrothermal fluids and the metals that they transport in solution‚ 3) available sites within the fractured rocks which allow for deposition of the minerals from solution‚ and 4) the requisite chemical reactions that contribute to that deposition (Bateman‚ 1967)
