The Mariana Trench By: Alex Jensen
What is the Mariana Trench A trench is a type of dip or hole in the ocean floor The Mariana Trench is the biggest most deep trench in the world Mariana Trench general facts Location: Pacific Ocean, east of the 14 Mariana Islands
Depth: 35,838 feet deep; deepest point of the world, 7 miles deep Temperature: 1-4 degrees celcius or 33.8- 39.2 degree Fahrenheit The Mariana Trench is 1,580 miles long and 43 miles wide Thats about the distance from New York City to Denver Colorado The Pressure at the deepest part of the Mariana Trench is over 8 tons per square inch. This means about 4 adult elephants stacked on top of each other in a square of 1 inch. That is over one thousand times the gravity that you are used to. Discovery of the Mariana Trench First discovered in1875 by British ship, HMS Challenger. In 1951 a British Survey ship Challenger II used modern sonar to find official deepthes. The deepest point discovered by Challenger II was named "The Challenger Deep" after the ship. January 23, 1960: Trieste dived to the bottom of the Mariana Trench; very first humans to do so HH On March 2nd of 1996 Kaiko, a Japenese remotely operated underwater vehicle, dived down 35, 798 feet to the bottom of the trench The latest decent in the Mariana Trench was in 2009 when Nereus, an unmanned probe from the US, dove to the bottom In all there has only been three decents maned and unmaned into the Mariana Trench The deepest point of the Mariana Trench is called The Challenger Deep
