WitrynaA common misconception is that magma comes from the Earth's molten core. It really comes from the mantle, the layer between the core and the crust. The mantle is solid, but it shifts and becomes fluid due to changes in temperature and pressure. The tectonic plates, which carry continents and ocean floors, rest on top of this mantle. Witryna19.

Witryna14 gru 2024 · The lunar magma ocean (LMO) hypothesis suggests that as magma oceans begin to solidify, they first crystallize to form olivine, which, due to its higher density, sinks toward the bottom of the magma ocean as it crystallizes and differentiates [50,51]. The impact basin formation is responsible for the exposure of olivine. Witryna12 gru 2016 · Oceanic Convergence is where oceanic and continental plates meet. As oceanic plates are denser they go down toward the Mantel; this is subduction. Sediments that have accumulated at the bottom of the ocean form land mass as they rise as they melt due to the magma, through the continental crust and then re appear as the …
