Ocean Inside the Earth's mantle

The mantle takes up 84 percent of the Earth's structure and is composed of my different layers. Knowledge of the upper mantle is that it includes tectonic plates, magnetic pull, heat flow, and gravity studies. A new discovery has been made and scientists have discovered an ocean on the Earth's upper mantle near Asia as big as the Arctic ocean. This proof was found as a seismic wave diminishing into the Earth's mantle during earthquakes. Researchers estimate that up to 1 percent of the rock sinking down into the Earth's mantle, in the part of which is water, works out to be what the Arctic Ocean is worth (Than printout1). Water in the

Wysession noticed the waves on the siesmograms began to diminish in one area beneath Asia. Traditionally, seismologists employed a sort of CAT scan by measuring the speed of seismic waves (Anitei printout 1). “Water slows the speed of the waves a little”, Wysession explained. “Lots of dampening and a little slowing match the predictions for water very well” (Than printout 1). Predictions were evaluated stating that a cold slab of the ocean floor could have sank miles into the Earth's mantle leaving the hot temperatures of the mantle to evaporate water stored in the rocks. When the water rises it appears to be a solid formation but the composition of rock in the ocean is said to be 15 percent water. This is very accurate, but Wysession points out that it is “A real back of the envelope type of calculation”(printout 2). Wysession has claimed the new project to be The Beijing anomaly because of the high waves formatting under the capital of China. This is going to be the beginning of a new technology break through towards finding water beneath the surface of the earth much deeper than what submarines or other like items can

    The mantle itself is set between the crust, and the outer core of the earth. The mantle is by far the largest divide of the earth, measuring around 2900km thick, which is almost 85% of the earth’s volume. So the mantle is divided into four sections. The upper mantle (35 km- 400 km), the transition zone (410–660 km), the lower mantle (660–2900 km), and the core-mantle boundary (varies but normally 200km thick).…

    The origin of earth’s magnetic field is a result of molten metal in the outer core that circulates around the inner core like a giant dynamo. Magnetism of the lithosphere supports the model of plate tectonics through the development of new oceanic crust that formed volcanism at the ridge crest in the prevailing polarity. This new crust was split apart and then moved in opposite directions. This explains new lithosphere at mid oceanic plate margins.…

    This lab uses earthquake data to construct profiles of two convergent boundaries: the Tonga Trench and the Peru-Chile Trench. Where two tectonic plates converge, if one or both of the plates is an oceanic lithosphere, a subduction zone will form. When crust is formed at a mid-ocean ridge, it is hot and buoyant meaning it has a low density. As it spreads away from the ridge and cools and contracts, or becomes denser, it is able to sink into the hotter underlying mantle. When two oceanic plates collide, the younger of the two plates, because it is less dense will ride over the edge of the older plate. The density of the rock that makes up the subducting plate determines the way in which a plate behaves. A plate with a greater density subducts into the mantle faster and at a steeper angle than a plate with a lower density. The age of the crust involved in the subduction also affects the rate at which it subducts. Older crust is cooler and denser therefore it suducts at a steeper angle and faster than new crust at a subduction zone. The three key features associated with a subduction zone are a deep ocean trench, a volcanic arc on the overriding plate parallel to the trench, and a plane of earthquakes, shallow near the trench and descending beneath and beyond the volcanic arc. Most earthquakes occur at tectonic plate boundaries. The largest earthquakes are associated with subduction zones because they have long continuous fault lines. The depth of its focus can classify an earthquake. Earthquake depth range is divided into three zones: shallow, intermediate, and deep. Shallow earthquakes are between 0 to 70 km deep, intermediate earthquakes are between 70 to 300 km deep, and deep focus earthquakes have foci at more than 300 km.…

    Welcome! in this address. Today's discussion is about puzzle of earth. Earth conformed to 4.54 billion years back by accumulation from the sunlight based cloud. Volcanic outgassing presumably made the primordial climate and after that the sea; however the environment contained no oxygen, thus, would have been harmful to most present day life including people. A significant part of the Earth was liquid on account of incessant impacts with different bodies which prompted compelling volcanism. A "mammoth effect" crash with a planet-sized body is thought to have been in charge of shaping the Moon. After some time, the Earth cooled, bringing on the development of a strong hull, and permitting fluid water to exist at first glance. Living structures…
