Mantle plume

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…

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…

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 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!…

Archie comics has made a comeback in this decade, and this time, it’s taken a deep twist. Riverdale, a popular teen drama, with a hint of mystery, directed by Lee Toland Krieger, carries the character names, and majority of the previously construed mannerisms that belong to the hit comic book series.. This series explores the mystery that comes with the death of a rich and popular teen, Jason Blossom, while the town is sitting on edge to find his killer, and the drama that is high school, slowly…

Foreword There are a multitude of environmental issues created by traditional urban design systems. One major issue facing urban and suburban areas is the Urban Heat Island Syndrome. An urban heat island is the effect of built environment and human activity on ambient air temperature. Basically, concrete and asphalt structures with human activity can absorb high levels of heat from the sun. According to the EPA, buildings and pavements can heat up to 90oF hotter than the air; then in the…

Urban sprawl is an inattentive issue that continues to harm the future of the world, unless the problem is addressed. The concept of urban sprawl is the “uncontrolled spread of urban development into neighboring regions” (“Urban Sprawl”). Across the globe, there has been urban sprawl in major cities, without consideration of future consequences. As society focal point is on celebrities and fashion, the focus on the destruction of the environment is not being acknowledged. The sprawl leaves…

the Indian plate, the Reunion island hotspot, and the evolution of lithospheric mantle structure. Keywords: deccan, mantle, plate, hotspot, reunion, reconstructions. The Deccan traps of West India, located on the Deccan plateau, the traps are one of the largest volcanic formation on Earth. The traps consist of hundreds of layers of solidified basalt, or igneous volcanic rock, measuring over 6,600 ft thick. The Deccan…

The first moon, Io, is the closest to Jupiter of the Jovian moons, however, it is Jupiter’s fifth closest moon orbiting at roughly 262,000mi. Though it is slightly larger than our own moon, for Jupiter is it only the third largest. Ganymede, Io, and Europa are in orbital resonance with Jupiter, and this causes their orbits to become elliptical. Io’s orbit takes it through Jupiter’s magnetic lines of force causing it to generate electrical currents. These currents travel along Jupiter’s magnetic…
