mostly occur at plate margins. They can also occur at hot spots and in rift valleys. The most active volcanic zone is the Pacific Ring of Fire around the Pacific plate. Here plates are colliding or separating. At active points on these plates volcanic mountains are formed‚ e.g. Nazca Plate and South American Plate‚ where plates separate‚ e.g. Pacific and Nazca Plate and in rift valleys‚ e.g. African Plate‚ Kenya. The most active area on the globe is the western rim of the Pacific Plate - stretching

a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40‚000 km (25‚000 mi) horseshoe shape‚ it is associated with a nearly continuous series of oceanic trenches‚ volcanic arcs‚ andvolcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes.[1] It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt. About 90%[2] of the world’s earthquakes and 81%[3] of

The theory of plate tectonics According to the generally accepted plate-tectonics theory‚ scientists believe that Earth’s surface is broken into a number of shifting slabs or plates‚ which average about 50 miles in thickness. These plates move relative to one another above a hotter‚ deeper‚ more mobile zone at average rates as great as a few inches per year. Most of the world’s active volcanoes are located along or near the boundaries between shifting plates and are called plate-boundary Volcanoes

Techniques for Isolation of Pure Cultures Objective : i. To perform the spread plate and the streak plate inoculation procedure for the separation of the cells of a mixed culture so that discrete colonies can be isolated. ii. To prepare a stock culture of an organism using isolates from the mixed cultures prepared on the agar streak-plate and/or the spread plate. Introduction : In order to be able to adequately study and characterize a certain microorganism‚ microbiologists need to separate

effect of different pH level of the Agar plate to the antibacterial activity of Santol (Sandoricum koet jape). Specifically‚ the study will seek for the answer of the question: 1.) Is there any difference on the No.of colonies after applying Santol (Sandoricum koet jape) extract on the Agar plate with pH level greater than seven (base)? 2.) Is there any difference on the No.of colonies after applying Santol (Sandoricum koet jape) extract on the Agar plate with pH level less than seven (acid)

crust is made up of seven major plates and a number of minor plates. The plates move because of the convection currents in the mantle caused by temperature differences within the mantle‚ leading to volcanoes and earthquakes‚ the world’s major geophysical hazards. The movement of plates due to convection currents results in a variety of types of plate boundary‚ each of which gives rise to particular types of hazards. Constructive boundaries occur where two plates are moving apart. Basalt rises

rate. New geological features‚ rock formations‚ and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn’t rest. Through the churns and molds‚ the twists and turns‚ Earth is active because of plate tectonics and the rock cycle. The ideas and theories that make up plate tectonics have shown Earth’s dynamism. The position of plates on global maps didn’t always look similar to the maps shown today
