Mantle

Earth has a core composed of two distinct parts: the inner core and the outer core. Both parts of the core are made up of mostly iron and some nickel. The difference is that those minerals in the inner core are solid and the same minerals in the outer core are liquid. The subsequent layer is the mantle which is sitting on top of the outer core. This layer is by far the thickest layer of Earth. Similar the core, the mantle contains mostly iron but in the form of silicate rocks. The mantle can also be divided into two portions, the upper mantle and the lower mantle. The lower mantle is completely solid since the pressure is too excessive for it to melt and flow. The upper mantle is also known as the asthenosphere, which flows as convection currents. Convection occurs in all fluids and is the rising of warm particles and sinking of cool particles. This convection flow of the asthenosphere has a large impact on Earth 's lithosphere, the outermost layer of the planet. The lithosphere contains both the crust and a small portion of the upper mantle. The lithosphere is very rigid; it does not flow like the asthenosphere. The crust itself, which is contained in the lithosphere, can also be divided into two parts, the continental crust, and the oceanic crust. The continental crust is composed mostly of granite unlike the oceanic crust which consists of a volcanic lava rock called basalt. Basaltic rocks of the ocean…

The mantle is the second outermost layer in the Earth, and boy is it hot! The deeper down you go, the hotter it gets, all the way to 3,000 degrees celsius! Part of the mantle is liquid, and is made of oxygen, silicon and iron, and part is solid, and is made of iron and magnesium. These rocks are very shiny and beautiful to look at, so be sure to bring your cameras! While in the mantle, you will be experiencing increasing pressure, but as long as you swallow to pop your ears, you should be fine!…

earthquake. Luckily, by the underwater crest splitting apart, their job at getting deeper into the Earth’s core has become a whole lot easier----if they can maintain control of their ship. The controllers at the briefing room indicate that the ship is going too fast in the crosscurrent. Brazzleton explains the ship does not have enough pressure to deploy the laser. They cannot power up the ship in time to approaching the gateway into the Earth’s crust. The ship just manages to deploy a laser to…

how come our oceans don't always change in shape? These are questions that have been asked before. When i explained the idea of how plate tectonics may have been the right answer to these questions i only stated that this could be a reason why the ocean has its shape. Plate tectonics according to google's dictionary is “a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the…

The University of Oklahoma has long been a powerhouse for pumping out athletes, politicians, and other highly educated and gifted individuals. However, one in particular sticks out: Mickey Mantle. Mantle is possibly one of the most influential players in the Major League Baseball’s history. Because of his switch-hitting abilities and his outfielding skills, he was a most famed and renowned player in the world. He was on twelve World Series teams, seven of which he clinched the title along with…

Thus, volcanoes can be found along tectonic plate boundaries. However, Hawaii is not located at tectonic plate boundaries, but in the north central part of the Pacific plate. As with all tectonic plates, the Pacific plate has a predominant direction of flow as it floats over the viscous mantle of the earth and is moving in a northwesterly direction at a rate of 7 to 11 centimeters…

I guess I am not shocked at the fact that Mickey Mantle received preferential treatment over people who were probably on a waiting list before him or who had never touched a drop of alcohol in their life and needed a liver for other reasons. He was probably not the first and definitely not the last. I remember another very famous alcoholic, Larry Hagman who played J.R. on Dallas. There was a lot of backlash, after Larry announced he had cancer and 2 months later he was undergoing surgery…

What is the acid mantle and why is it important? The simple answer is that the acid mantle is the thin layer on your skin that protects it against acne causing bacteria and moisture loss. When it’s intact, your skin looks and feels healthy and radiant. Because this thin layer is so important, we thought it’s high time it gets a little shine and be explained in more detail. What is the acid mantle? It is a very fine layer that is found on top of the outermost layer (stratum corneum) on top of…

baseball is the great New York Yankees center fielder Mickey Mantle. He was born on 20 October 1931 in Spavinaw, Oklahoma. Though the eyes of the sports fans Mickey Mantle was the most popular, athletic, sought out player of his time. His rookie year started in the spring of 1951. He teamed up with other well know Yankee players such as Joe DiMaggio, Yogi Berra, and Phil Rizzuto which lead to them winning their 4th world series in 1953.

The Great Life of Mickey Mantle Number 7. A baseball Hall of Fame number that will always be remembered in professional baseball. However, a number is just a number without the man who made it great. That man was Mickey Mantle. Born during the Great Depression, this did not define Mickey Mantle, who seemed destined to have a stunning career in baseball, but Mantle will also be remembered for his life outside sports and his legacy. Mickey Mantle grew up a normal boy in rural Oklahoma. He was…
