Plate tectonics

Japanese farmers have been able to harvest two crops of rice annually since early times, but it is very mountainous and only has about twenty percent of land suitable for cultivation. Japan is located at the juncture of the Asian and Pacific tectonic plates, and the mountains are volcanic in origin. An advantage of this is that volcanic soils are extremely fertile, causing high productivity of farmers. A disadvantage is that it is prone to earthquakes. It is significant that Japan is an island…

Specific purpose: To inform the audience on what happened to Pompeii. Central Idea: Mount Vesuvius is a dangerous active volcano that has the potential to cause the equivalent damage or worse even today. Introduction I. “I looked round: a dense black cloud was coming up behind us, spreading over the earth like a flood. Many besought the aid of the goods, but still more imagined there were no gods left, and that the universe was plunged into eternal darkness for evermore.” A. These were the words…

1. Introduction The Thera Catastrophe is a topic of debate for many scientists around the world. The eruption happened around 3500 years ago. The main issue today is how disastrous was the impact of the of the eruption and the resulting tsunami. 1.1 Santorini Island The Thera volcano is located in the west part of the Mediterranean on the island of Santorini in Greece. (Figure1) The disaster had a massive impact on all aspects of the region. The consensus in the scientific community is the…

each other and catching one another. Scientist call these puzzle pieces tectonic plates, and the edges of the plates are known as the plate limits. The plate limits are made up of numerous flaws, and the vast majority of the seismic tremors around the globe happen on these shortcomings. (USGS, pg 4). Since the edges of the plates are harsh, they get stuck while whatever remains of the plate continues moving. At last, when the plate has moved far enough, the edges unstick on one of the…

the element neodymium. By measuring the relative abundances of the isotopes in a rock, geochemists can tell whether the rock originated in the mantle lithosphere -- the slice of the North American jelly sandwich that, according to Bird, the Farallon Plate had dragged away. When the chemists checked the neodymium, however, the rocks proclaimed that the mantle lithosphere is very much intact. The evidence was compelling; many of Bird's colleagues abandoned his version of the Laramide orogeny.…

(Ring of Fire, n.d.)” It is about 40,000 kilometers long and bounds most parts of the Pacific plate. The frequency of earthquakes is vital so they have have to ensure the protective strategies to develop in order to avoid massive loss of life in the world. Emerging megacities that lie in zones of high seismic risk have been put on high alert by most…

miles of highway. Mount Saint Helens had been dormant for the past one hundred twenty-three years. The volcano was also a strato-volcano. The volcano is part of the Cascade Volcanic Arc. A volcanic arc is a chain of volcanos formed over a subduction plate. The Cascade Volcanic Arc is a major range of volcanoes stretching all the way from British,…

Leonardo Da Vinci Leonardo was born on April 15, 1452 in Vinci, Italy during the Renaissance period. His parents had him out-of-wedlock. He was raised primarily by his father and his stepmother. Though he obtained no formal education, he would eventually go on to apprentice under the famous painter Verrocchio. During the six years Leonardo would spend with Verrocchio, he would obtain some new skills such as metal work, carpentry, leather work, drawing and sculpting. In 1472, at the tender age of…

buildings. "Within an hour after the earthquake shock the smoke of San Francisco's burning was a lurid tower visible a hundred miles away." It was May 5, 1906. In San Francisco when buildings burned down due to the fire. The fire was caused by tectonic plate movement or a earthquake. They blew up some of the buildings in a useless attempted to prevent it from spreading to the rest of…

To me, astronomy is the study of the universe and everything in it. This includes the planets, moons, stars, comets, etc. The major difference found between Muggle astronomy and Wizarding astronomy is that the Muggle world has "laws" that explain what they see in the universe. The study of these laws of the universe in the Muggle world is called "physics". Although these laws do explain a vast majority of what the Muggles see on Earth and in the universe, it may not hold true in the Wizarding…
