It is believed that the inner core is solid because of the extremely high pressure that would make it impossible for the iron to melt. In time, this shedding will transform the unstable element into a slightly different but stable element. 5.515 g/cm3. These cookies do not store any personal information. Diamonds form deep within the planet when carbon is compressed under incredibly strong pressure. Hutton's estimate on the mean density of the Earth was still about 20% too low, at 4.5 g/cm3. When an earthquake takes place, it releases pressure waves which then propagate throughout the entire planet. [33][34], Recent evidence has suggested that the inner core of Earth may rotate slightly faster than the rest of the planet;[35] however, more recent studies in 2011[which?] Copyright © Science Struck & Buzzle.com, Inc. That motion generates electrical currents. You also have the option to opt-out of these cookies. uranium     The heaviest naturally occurring element known. For instance, a plant or animal’s range is the area over which it naturally exists. The outer core is liquid, and scientists believe it is made up of iron, smaller amounts of nickel, and some other lighter elements in trace amounts. There is a model that explains this asymmetry with melting on one side and crystallization on the other. A boundary known as the Mohorovicic (or simply Moho) discontinuity can be found in between the crust and the mantle. We hope you are enjoying ScienceStruck! The temperature of this layer can reach up to 1600 °F at considerable depths. It is again enveloped by the atmosphere, which comprises five major layers, namely, the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The thickest part of Earth’s crust is about 70 kilometers (43 miles) thick and lies under the Himalayan Mountains, seen here. magnesium     A metallic element that is number 12 on the periodic table. These plates move slowly, and sometimes bump each other and cause earthquakes. It is also thought to suffer very violent convection currents – hey, and guess what? Is teaching social studies important? During Earth’s early formation, the planet underwent a period of differentiation that allowed the heaviest elements to sink to the center and lighter ones to rise to the surface. Under the oceans (and Hawaiian Islands), it may be as little as 5 kilometers (3.1 miles) thick. In subduction areas, where one plane goes beneath another, earthquakes have been observed at depths of up to 670 km. It’s also intensely hot: Temperatures sizzle at 5,400° Celsius (9,800° Fahrenheit). Dynamo theory suggests that convection in the outer core, combined with the Coriolis effect, gives rise to Earth's magnetic field. core     Something — usually round-shaped — in the center of an object. The oceanic crust is the type found beneath the ocean. Together, this uppermost part of the mantle layer and the crust are known as the lithosphere. The core has a radius of 750 miles. magnetic field     An area of influence created by certain materials, called magnets, or by the movement of electric charges. By Benjamin Elisha Sawe on August 1 2017 in Environment. Schematic view of the interior of Earth. It is mandatory to procure user consent prior to running these cookies on your website. The four main layers of the Earth are the crust, mantle, outer core, and the inner core. Experimental evidence has at times been critical of crystal models of the core. The mantle is separated into the upper and lower mantle. As time moved on, the Earth cooled down and is still cooling, as of today. Also a term for any sunlike star. This process occurs in the outer layers of some stars. Temperatures within the core can reach over 10,000 Fahrenheit and the layer contains mostly iron and nickel elements with heavier mineral deposits of gold, silver, platinum, palladium and tungsten.
