Oceanic trench

In the Figure 1 schematic view of the ocean bottom, the vertical scale is given in kilometers (km). This vertical scale is vastly different from the horizontal scale. The vertical distance between scale markings is [(1)(10)(100)] km. 2. The ocean trench in the schematic view has a maximum depth of [(8)(80)(800)] km below sea level. 3. The distance between scale markings on the horizontal scale is 100 km. Comparison of the vertical and horizontal scales indicates that the vertical scale is exaggerated

most highly active volcanic regions of the world, part of the Pacific Ring of Fire, and formed by the subduction of the Pacific Plate and the Philippine Sea Plate boundaries. The islands themselves were formed by eruptions of lava due to undersea oceanic plate convergence over fifteen million years ago. Nishino-shima's coordinates lie at 27.247°N / 140.874°E, and is one of the youngest islands, believed to be only ten thousand years old, with the last active vent erupting in 1973. The Ogasawara Islands

disaster caused. It was reported to have hit a magnitude of 9-0 with the epicenter being located at least 80 miles away. The focus was 18.6 miles lower than the western Pacific. The result was a rapture of the subduction zone and thus led to the Japan Trench being affected. Several foreshocks reached as much as 6.0 and greater effects that ended up acting on the land in the following days and months even after the quake had subsided. The tsunami that accompanied the earthquake originated from a fault

Objective: How to find evidence of life in deep oceanic trenches near thermal vents Introduction: Deep ocean trenches are environments that have historically been shrouded in mystery, their inaccessibility rendering such limited explorations as net dragging and dredging for samples (Lee, 2012). While potential for chemosynthesis had been proposed as long ago as 1890, it was nearly a century later before such systems were demonstrated to be active on the ocean floor (German, 2011). Further investigation

Adapted from an activity by Laurel Goodell February 2013 Introduction to Plate Tectonics via Google Earth (24 pts) B. Topographic Patterns Uncheck all of the layers and focus on topographic features of the earth. Topography of the earth ABOVE sea level Questions Answers 1. Are mountains randomly distributed on the continents, or do they tend to occur in particular patterns (clusters, linear chains, arcs, etc.)? Some appear in lines and others in arcs 1pt 2. Find Mt. Everest, the highest point

The timbers were thought to indicate timber-lacing in the walls but are likely to support a wall- walk or a similar structure. Carbon dating has given us an age range of AD340 and AD610, which is according to MacKie (1969) for the construction of the fort. It has been claimed that the fort was Roman however MacKie (1969) argues with the evidence that it was built by Picts in the early parts of the period and did not exist during the roman occupation of southern Scotland (MacKie, 1969).

Exposure by Wilfred Owen 1. In the second stanza Wilfred Owens describes sounds of ‘mad gusts tugging on wire’ this emphasises the force and sounds of the wind. All the soldiers can hear around them is the sound of guns in the distance. The word “incessantly” means constantly for the men the gunfire seems never-ending. ‘the flickering gunnery rumbles’ has a rhythm, and may echo the distant, continuous sound the men can hear. The words 'gunnery’ and ‘rumbles’ is the use of onamonapia the author is

My dearest grandmother, It has been some time since I have written you but you see, I can never exactly find the time to. It’s the afternoon right now and I just finished my assigned duties. I’ve finally settled down in one place so I’ve decided to write you. I woke up today and remembered what day it is. Today, August 13, is grandfather’s 72nd birthday. Are the both of you celebrating together? Tell him I say happy birthday. I wish I could be there. Life over here isn’t bad. I know that you’re

American forces in the south, between 5,000 and 7,000 men, were based at Charleston under the command of General Benjamin Lincoln. Lincoln recognized that he would need assistance from the French navy and army to retake Savannah. On September 3, he learned that the French forces under the command of Admiral Comte d’Estaing were en route to Savannah, bringing with them ships-of-the-line and 4,000 soldiers. On September 11, Lincoln marched out of Charleston with 2,000 Continentals to link up with d’Estaing

My best friend. My biggest supporter. My brother. For those of us with brothers, we can easily say that they tend to be aggravating at times, but at the same time they can be one of the most positive influences in our lives. This describes my older brother Abraham, or Abe for short. All through my life, having him next to my side has been one of the greatest things that has ever happened to me. From the headaches of school, to the carelessness of child play, to now living in his house; Abraham has
