Crust

they travel speed path. Inconclusive this is how scientists learn about earth centered Crust Mantle and Core There are 3 layer of the crust mental and care. The crust is a layer that we stand on and a dry layer on the ocean floor there are thickest under…

lies in between these two plates that are moving away from each other slowly. Although as a result of the separation of the two plates earthquakes occur and magma comes out making new crust. The magma comes out from a series of volcanoes that cool to make new crust. Crust closer to the rift is newer than the crust farther from the rift. The splitting of the African and South American Plate makes a divergent boundary. A Divergent Boundary is made when two tectonic plates move away from each…

The layers of the earth according to depth were; crust, mantle and core with the crust being the outermost while crust the deepest. The characteristics of these layers vary in density, heat and nature. The crust is rigid, and the thinnest; especially in the oceanic regions. This is due to relatively uniformity of the ocean surface compared to the land; which is defined by large variations in topography including mountains and valleys. Beneath the crust, the mantle layer is found in a semi-solid…

almost all geologic processes. AS I’m sure you can imagine, the idea that the entire crust of the earth constantly shifts has dramatically altered the way we think of the planet we live on. In this essay we will look at the development of the theory of plate tectonics by ocean floor mapping, magnetic pole reversals, and seafloor spreading. First up is looking at ocean floor mapping. Nearly two thirds of the Earth's crust exist under ocean waters. No one really knew what the death of the ocean…

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…

thrust downwards and the other is thrust upwards. This creates a thickened crust and represents a fold mountain. An example of a fold mountain is mount Kosciusko. Mount Kosciusko was formed by elevating and folding granite rocks. Currently, it is eroding.The second type of mountain is the fault-block mountain, also known as the block mountain. These mountains form when there are faults or cracks in the crust. The earth's crust is broken into sections and these sections move up and down,…

It makes up 40% of the Earth’s surface and has a density of 2.6 grams per centimetre cubed. It has a thickness of 35-70 kilometres. Oceanic crust consists of dark coloured rocks made up of basalt known as mafic. Mafic is an igneous rock made of mainly magnesium and iron. Oceanic rock is also 7-10 kilometres thick. It has a density of 3 grams per centimetre cubed. 9. Define the terms subduction…

Unidentified Flying Object bases, really around 4km2 of space under the ground, not realistic. Sound Waves, it is believable having a sound that is tested as a weapon and having the same side affects of each other. And lastly, moving magma under the earth’s crust. In my opinion this is the most believable conspiracy. Like I said in the paragraph before this one, there is a lot of volcanoes around in this area, so this is the most sensible conspiracy in my opinion. In conclusion, after reading…

New crust is generated as plates pull away from each other and can either cause sea floor spreading or new land to be created. An example of a continental rift valley is the Eastern African Rift Valley which is being formed as the Eastern African plate is moving away from the main Africa plate in a north-easterly direction. Plates move apart due to convection currents in the lithosphere. As the crusts move away from each other the crust thins, tension in the lithosphere causes the plate to…

The s-wave is wave A. The p-wave is always going to be faster than the s-wave. Wave B starts at the velocity of about 8 km/s and wave A starts at about 4 km/s. Since wave A is moving slower, it is the s-wave. Wave A also reflected off the outer core and wave B refracted. The p-wave is wave B. The p-wave is always going to move faster than the s-wave. Wave B starts at the velocity of about 8 km/s and wave A starts at about 4 km/s. Since wave B is moving faster, it is the p-wave. The…
