thousand meters. The huge‚ brittle tectonic plates that make up Earth ’s crust normally move only a few centimeters per year‚ not fast enough to be noticeable in a human lifetime. However‚ in the East African Rift Valley‚ this tectonic motion is happening with remarkable speed. The East African Rift valley is an example of an active divergent rift‚ one of the few areas on Earth where a continent is being actively separated (rifted) by the ongoing forces of plate tectonics.

typical methods of measuring the discharge of an essentially incompressible fluid‚ whilst at the same time giving applications of the Steady-Flow Energy Equation (Bernoulli’s Equation). The discharge is determined using a venturi meter‚ an orifice plate meter and a rotameter. Head losses associated with each meter are determined and compared as well as those arising in a rapid enlargement and a 90-degree elbow. The unit is designed for use with the TecQuipment HI Hydraulic Bench‚ which provides the

A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

Liquiñe-Ofqui Fault Zone (LOFZ) might include other neighboring faults such as Reigolil-Pirihueico Fault. The geology of Chile is a result of the Andean and preceding orogenies occurring on the western coast of South America‚ a convergent boundary of tectonic plates. Chile is an active earthquake zone with recent years seeing an increase in high

RF #1 The name Lucifer has often been understood to be another name for the devil or the satan. This identification has a long history in the church‚ going back to at least the fourth century. Its origin is actually from a passage in the Old Testament from the book of Isaiah that‚ to some‚ speaks of a being cast out of heaven because of pride. Since some people see a reference to the devil being cast out of heaven in the New Testament (Rev 12:9-12; cf. Lk 10:18)‚ they assumed that the Isaiah passage

Ring. PLATE TECTONICS Plate tectonics is a theory that the earth is split up in to different areas of the world. They glide on the mantle of the earth the plates act like a hard ridged shell (fig 2 plate tectonics) Some of the plate tectonics move very slowly each year for example in Iceland there is a visible line where the plates are moving if the plates merge together they can cause mountains and volcanos. Mountains and volcanoes are formed buy two plates colliding together and one plate gets pushed

How tsunamis occur. As one plate subducts below another (moves underneath)‚ pressure builds for many years resulting in a section of the mega-thrust giving away. As this section gives away‚ it ruptures the ocean floor‚ resulting in a massive displacement of water‚ causing a tsunami. Tsunamis are barely felt as a ripple on the ocean’s surface‚ but as the waves reach land‚ they increase in size as the water becomes shallower.

Computer-Assisted Instruction and Science What Is Computer-Assisted Instruction? “Computer-assisted instruction” (CAI) refers to instruction or remediation presented on a computer. Many educational computer programs are available online and from computer stores and textbook companies. They enhance teacher instruction in several ways. Computer programs are interactive and can illustrate a concept through attractive animation‚ sound‚ and demonstration. They allow students to progress at their

between two plates causing major earthquakes. Sometimes when this plates are pushed together they form fold mountains or ridges. Today we know that the continents are gradually moving apart. Therefore the there is new rocks created in between those areas. New volcanoes are created and new rocks are formed. Plate tectonics allow scientists to know about the earth’s centre. The oceanic plate slides under the continental plate because it is heavier. Once it goes under the continental plate it melts
