method employed to evaluate the effectiveness of antiseptic agents against selected test organism. In this method‚ sterile filter paper disk is impregnated with an antiseotic and placed on fresh heavily inoculated agar plate of a test organism. Following incubation‚ the agar plate is looked for a zone of inhibition. The presence of a clear zone of inhibition surrounding the disk is indicative of inhibitory (antimicrobial) activity against the organism. This experiment deal with the evaluation of

different particles. The new particles that are formed when exposed to the elements are then in equilibrium. 2.) Minnesota is located on the North American plate. The Caribbean Plate is one of the closest boundaries and it is mostly a transform boundary but also has some areas of convergence. Another of the closest boundaries is the Juan de Fuca Plate and it is a convergent boundary. 3.) The most likely of the geologic hazards that could happen to Minnesotans is flooding and the possibility of landslides

Japan is located in three tectonic plate boundaries; the Pacific‚ Eurasian and Philippine Sea plates. A three way destructive plate boundary occurred as a result of a plate movement along the border between the plates. The Kobe earthquake was caused by pressure building as the Philippine Sea plate is subducted underneath the Eurasian plate. The further compressed Philippine Sea plate was affected underneath‚ likely the less compressed continental Eurasian Plate causing an increase of pressure of

the world and in relation to tectonic plate boundaries. For example you have highly destructive and explosive volcanoes often found along destructive plate boundaries because of increased pressure within the subduction zone. An example of this is the Philippines‚ which is situated above a destructive plate boundary and this leads to numerous and highly destructive volcanic eruptions. You also find volcanoes along constructive plate boundaries where the plates are moving apart and this is creating

to be where plate boundaries intersect with major storm belts and they are also in areas of high human concentration in low or medium developed countries because this effects whether or not the country will be prepared thoroughly enough and whether it can recover quickly. The Philippines lies on a boundary between the Philippine and Eurasian tectonic plates‚ whereby the Eurasian plate is sub ducted underneath the former; this is defined as a destructive plate boundary‚ as the plates move in series

CHAPTER I INTRODUCTION Background of the Study Mangrove swamps are forested intertidal ecosystems that occupy sediment-rich sheltered tropical coastal environments. By trapping and stabilizing fine sediments‚ mangroves control the quality of marine coastal waters. Aside from maintaining coastal food webs and populations of animals‚ mangroves have an important role in pollution control through their absorptive capacity for organic pollutants and nutrients‚ and they play an important role in storm

tectonic nature of the Earth. Such earthquakes are called tectonic earthquakes. The Earth’s lithosphere is a patchwork of plates in slow but constant motion caused by the release to space of the heat in the Earth’s mantle and core. The heat causes the rock in the Earth to flow on geological timescales‚ so that the plates move slowly but surely. Plate boundaries lock as the plates move past each other‚ creating frictional stress. When the frictional stress

1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

The Alps are the youngest and highest mountain system in Europe. They stretch across the western and southern part of the continent in a broad arc. The mountain range startsnear the Mediterranean Seaon the border between France and Italy. Then it curves north- and eastward through northern Italy‚ Switzerland Liechtenstein‚ southern Germany‚ Austria and Slovenia. The Alps are about 1‚000 km long‚ the broadest section over 260 km wide. The highest peak‚ Mont Blanc‚ situated on the border between

occur both on land and sea.They may occur at areas where plates collide (subduction zones/ convergent plate margins) ; where plates slide past eachother along fault lines (transform plate margins) or due to volcanic eruption. Earthquakes may be of three different categories: * Tectonic – movement in the earth’s crust due to sudden movement along fault lines. * Plutonic - occurs deep within the subduction zone of colliding plates. * Volcanic – earthquakes accompanied by molten lava
