Lithosphere

The Inner Core, Outer Core, Mantle, Asthenosphere, and Lithosphere, or, as more colloquially known, the five layers of the Earth. Although each layer is important, each living thing resides on the Lithosphere, which happens to rest on the Asthenosphere, the upper part of the Mantle. Forces caused by these two layers both contribute to the theory of Plate Tectonics, which happens to be interconnected to Earthquakes and Volcanoes. Without Plate Tectonics, the other two occurrences simply cannot exist, Of course, to comprehend how Earthquakes and Volcanoes work, Plate Tectonics must be understood first. So, to digress, it is the theories of Seafloor Spreading, proposed by Harry Hess, and Continental Drift, conceived by Alfred Wegener united under…

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…

Sciencia is a world analogous to Eath. Based on the present day plate boundaries and similarities on multiple continents, It’s believed that the continents of Sciencia were once together as a supercontinent called Edisonia. The supercontinent held 6 of the 8 modern continents, which broke apart due to tectonic forces in the Lithosphere. Also, the 7th and 8th continents were believed to have formed from volcanic eruptions on convergent plate boundaries. The edges on the modern- day Sciencian…

The topic of this discussion is to explain why Africa and South America are moving apart. The drifting apart of Africa and South America has to do with the theory known as the theory of plate tectonics. Based on this model, the crust the coolest part of the mantle, make up Earth’s strong outer layer, known as the lithosphere. Right beneath the lithosphere is the asthenosphere, the hottest part of the mantle. Rocks at this depth are very near the melting temperature, and respond to forces by…

Plate Tectonics is an example that attempts to explain the beginning of patterns of deformation in the crust, continental drift, earthquakes, and mid-ocean ridges. Two major properties of plate tectonics are the lithosphere, and how it's broken into numerous segments in constant motion and evolution. The prime theory of plate tectonics, seafloor spreading, states that the new lithosphere crust is formed at ocean ridges and moves away from ridge axes with a motion like that of a conveyor belt as…

within the Deccan continental flood basalt. By using a seismic tomographic model, Forte and Gilsovic were able to find two plumes only a few degrees south of the Reunion island hotspot; one below the mid-ocean ridge that separates Madagascar and the southern part of indian and another beneath the modern day Marion hotspot, of the southern coast of South Africa. The discovery of these two plumes are important evidence of reconstruction occurring around the Indian plate, including the Reunion…

the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle”. The reason why this could possibly be the reason why the ocean looks and occupies the world in the way it does, is because the process of the core to the crust is shifting and that cause all other things to shift as well. It is pretty much saying that when something happens, another will follow. The shifting of the core and the crust has…

The ocean crust has basalt and continental crust. And it is also contains solid hot rock and that can get up to 300 km lithosphere is also part of the crust in conclusion there are many ways that a sanction can explore and learn about earth. Types of Heat There are 3 main thing of heat the first one is heat transfer. Heat moves from a warm object to a cooler object. the second type of heat transfer is conduction . Conduction is heat transfer between object…

as we move away from it. The oceanic seafloor is much younger than the continental crust. Some of the oldest sea floor can be found in the Mediterranean as it hasn’t been subsided in this region. The oldest sea floor is often found in places where rifting has stopped. 2 4 Heat Flow Models As it was realized that the heat flow was is highest at spreading ridges and then decreases with distance, the relationship between age and heat flow became the primary constrain for most oceanic models.…

Chapter 3 Objectives Distinguish among lithosphere, hydrosphere, atmosphere, and ecosphere. -The lithosphere consists of the crust and upper mantle of the Earth. In the lithosphere there is nonrenewable fossil fuels, minerals, soil, and renewable soil chemicals. -The hydrosphere consists of the Earth’s water. This includes liquid water, ice, and water vapor. -The atmosphere consists of the fine membrane of air surrounding the planet. -The ecosphere is also known as the biosphere. It includes…
