The Discovery Of The Ocean Trenches Essay

One evidence of this theory is molten material. Molten Material is magma erupting from mid-ocean ridges. Alvin the submarine found weird rocks shaped like pillows or toothpaste. This tells us this magma cools quickly underwater. Another type of evidence are magnetic stripes. Magnetic stripes are patterns in the ocean floor to prove Earth’s magnetic field has reversed itself in history. Scientist also looked at the “magnetic memory” of the rocks. Scientist drilled pipes through water to drill holes into the ocean floor. Scientists discovered that the older rocks were further away and younger rocks were closer. Those were the three types of evidence that scientist used to support the theory of Sea Floor Spreading.

The reading that I chose for this assignment is from Chapter Six in the required book for class “The Sixth Extinction: An Unnatural History”. The chapter title is “The Sea Around Us” where the primary concentration of the chapter was the consequences that humans have on the planet with the focus on ocean acidification. This happens from the carbon dioxide we pump into the air and it slowly seeps back down into the oceans and slowly increases the PH level thus causing the ocean to be more acidic. In about one hundred years do you believe that, oysters, mussels, and coral reefs survive?

The film The Sea Inside shares the heart warming real life story of a man named Ramon Sampedro. At the young age of twenty-six he suffered an accident while diving into shallow waters of the ocean that left him a quadriplegic. Now at the age of fifty-four, Ramon must depend on his family to survive. His older brother Jose, Jose’s wife, Manuela and their son Javi do their best to take care of Ramon and make him feel loved. Although Ramon is extremely grateful to his family and friends for their help all these years, he has come to see his life as aggravating and unsatisfying. He wishes to die with the little dignity he has left in his life. However, Ramon’s family is dead set against the thought of assisted suicide and the

Oceanography also called oceanology or marine science, is the branch of Earth science that studies the ocean. It covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within it: biology, chemistry, geology, meteorology, and physics as well as geography.

The deepest depths of the ocean are unfathomable, no one knows what creatures lurk down there.

To begin with, if I was currently an advocate for the environment and animals I would first focus on the Orcas, or killer whales, at theme parks, specifically Sea World. First of all, Sea World is inhumane. Five of the Orcas currently at sea world were “whale-napped” from the oceans they called home. For example, Tilikum, one of the most know whales in the Sea World franchise, is now thirty-two years old. He was captured at the age of two by, which means he has been in captivity for thirty years. And, before anyone says Tilikum was injured so they “rescued” him I want to say that it is fact that Tilikum was not injured. He was taken from his family and confined to a tiny tank just so people could make a hefty profit. Also, if the Orcas are

World War I left a lasting impression on the world. New weapons such as tanks and poison gas turned the war into a “war of attrition.” Trench warfare was primarily used in this war and the conditions there were part of the reason why millions of people died. The war remained a stalemate between the opposing sides until the United States made the decision to join the war on the side of the Allies. This changed the course of the war and the Allies beat the Central Powers. Many factors in Europe contributed to the start of the war. Later, other reasons forced America to join the war which would leave drastic results.

I search for a game in Star wars battlefront I search for a Blast because that’s my favorite game mode and I’m good at it. I finally see a game pop up, just in to because I was the last person to join. There are ten people on each side ten for the Empire ten for the Rebels ( I was the tenth person on the Rebels). I soon find out that we are playing on Sulfur Fields on the planet Sullust. I finally pick my blaster the TL-50 Heavy Repeater the most overpowered gun in the game. I start to pick my hand I see so many star cards to choose from like homing shot,scatter gun, cycler rife,and then I see it, the bowcaster. The bowcaster is what Chewbacca uses as his primary but I can only get it for a star card, so I put that in my hand then move

World War One that was fought between the Allies and the Central Powers that brought about some of newest weapon tactics and strategies to its day. The war was fueled by several different contributors such as Nationalism, Imperialism, and Alliances that devastated the world. But one of the largest was Militarism which changed the fighting style of a primitive face-to-face combat to systematic style of battle through trenches. As this new style of fighting started to take over, countries developed new weapons and tactics to succeed over their enemies. This new Trench warfare continued throughout World War One by causing millions of men to die from modern weapons and horrid living conditions.

Infantrymen carried rifles that were lethal at 500 yards and used large magazines. Machine guns

and identified how it changed as the Earth warmed. It suggests a massive reorganisation of ocean

We think that daily spot hire rate will likely decrease next year. There are two reasons. First, there are 63 new vessels scheduled for delivery in 2001 to increase the supply of vessel and only few old vessels need to be retired, while the demand will not increase because imports of iron ore and coal would remain stagnant over next two years. Second, exhibit 5 shows that avg. spot rate of 2000 was higher than the rate of previous years and avg. 3-yr charter rate. In addition, the market will seemingly go up after two years. Therefore, ship owners should hope to sign short-term contract through using lower daily spot hire rate rather than locking low daily high rate for a long period.

When referring to Arizona’s water Kris Mayes, chairwoman of the state’s utility regulatory panel once said, “How do you say just how valuable water is in an arid state like Arizona?” she said. “It’s like the credit-card commercial-it’s priceless” (McKinnon). She was right, because in a dry state like Arizona, water is pretty important. To say water is ‘pretty important’ for the world is an understatement. We use water to function. And when we think of water we think of saving it. Keep the faucets from dripping or turn off the water while brushing your teeth. There are numerous tips for water conservation, but people don’t often think of the damage that is already done. Damages like ‘dead zones’. Dead zones in the ocean have been around for

the deepest marine trenches in the world (Rosenburg no. 6). With the interaction of the strong currents over the many reefs the topography is in a state of constant flux and development of new navigational hazards is swift (Rosenburg no. 6).

For many years humans have struggled to discover the deepest parts of the ocean and have also struggled with discovering space. We could not go really deep into the ocean, because humans can not withstand the pressure that the ocean produces. But now there is a robot that can reach the ocean floor called “The Benthic Rover”. With that new robot, scientist will be able to record how changes on the surface of the ocean will impact the marine animals below. “What is special about the rover is that we will be able to stay in the deep parts of the ocean for a really long time collecting seasonal changes data” (Engineer Alana Sherman). With Benthic Rover,
