Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks) Your main factors can be put into two simple categories. Human and physical. From there you can then further explore the factors. In my essay I will mainly focus on viscosity‚ location‚ settlement and perception and explore how the physical and human factors intertwine with each other through one simple idea that physical factors dictate the hazard while human factors exacerbate the hazard. From

the mid-ocean ridges because they are divergent plate boundaries.-areas where earth’s lithospheric plates are moving away from each other. The movement causes the crust to be very "thin ". The thinning allows the magma to come to the surface and form a volcano. Volcanoes can also occur at tectonic plate boundaries because Volcanoes form where the earth’s crust is thin and the magma can flow to the surface easier. This happens mostly at the edge of the plates. Volcanoes lastly can occur at subduction zones

The plates was incubated for five (5) days and its zone of inhibition was recorded. Preparation of Culture medium The powdered medium of Potato Dextrose Agar (PDA) was prepared following

location and plate tectonic settings can easily help show why more than 50 eruptions have occurred in such a short period of geologic time. The Galapagos Islands are located on the equator west of the South American coast. Like many oceanic islands‚ they are formed by a mantle plume or hotspot like Hawaii. A major subduction zone currently sits under the islands‚ the two plates that are subducting beneath the South American and Caribbean plates are the Nazca and the Cocos plates. The Galapagos

Lab12-Medical Microbiology- Part1– Differential Media/Biochemical Tests‚ Sp2012 (Set all of your margins to ½”) Purpose: The purpose of this lab is to help you become a little familiar with some of the tests that can be typically performed in a clinical or research lab facility. These tests may help in determining a particular pathogen’s growth needs. There are several sections to this lab. Find each section and complete the “Preparing for Class” sections.

samples of different concentration of protease. In this experiment‚ a plate of milk agar is needed for comparing the result of each sample. Circular wells were dug on the milk agar plates by the use of cork borer‚ and extracts could be put into the wells by dropper. One must note that milk-agar is white in color due to casein. If protease is present‚ casein will be digested by the enzyme giving a clear zone in the milk-agar plate. The size of the clear zone can help us to determine whether fruits differ

for this lecture Why Learn Earthquakes? Plate Tectonics they are not static they always move. they are moving in a limited space it will cause friction when it moves moves very slowly a few centimeters a year. slides past each other and radiated seismic energy. as it travels it causes shaking. seismic waves from epicenter cause a lot of shaking Continental drift pangea moved and separated into different continents. SF 1906 the plate moved 400 km past each other creating 8.2 earthquake

“The extent to which tectonic processes represent hazards depends on when and where they are experienced.” Tectonic hazards are dangers caused by the movement of the earth’s plates. The majority of hazards represent by plate tectonic occur at plate margins where two plates meet. These natural processes become hazardous when they affect people and cause material losses such as the destruction of infrastructure as this inhibits sustainable development. These hazards can be reduced depending on when

agar plates divided into 4 equal sections were used for this experiment. Each section was labeled with a number from 1-8. 8 Sterile swabs were used‚ 1 for each surface swab. 8 surfaces in my home were then identified that could serve as a fomite and swabbed with a sterile swab that was dipped in distilled water to moisten it. Surface #1 was the garbage disposal in the kitchen sink. It was swabbed and the microbes transferred to the appropriately labeled section marked #1 of the agar plate. Surface
