15. The mantle has layers - Lithospere, Aesthanospere, Mesosphere. Only Aestahnosphere is molten or plastic, Mesosphere and lithosphere are rigid or solid. Hence, when the question says "most of the mantle is molten", it is FALSE.
Fluid-fluxed melting is the second-most common melting mechanism that generates molten rock (magma). Which of the following best describes this partial melting process?Group of answer choicesWater released by metamorphic reactions from a subducting plate lowers the melting temperature of the upper mantle above the subduction zone causing partial melting of this upper mantle.Intrusion of basaltic magma into the continental crust partially melts the continental crust which has a much lower melting temperature than basaltOuter core injects into the upper mantle,...
Decompression melting is the most common melting mechanism that generates molten rock (magma). Which of the following best describes this partial melting process?Group of answer choicesRock is buried and melts as pressure increases leading to partial meltingSolid mantle rises and partially melts as pressure decreases.Water released by metamorphic reactions from a subducting plate lowers the melting temperature of the upper mantle above the subduction zone causing partial melting of the upper mantleIntrusion of basaltic magma into the continental crust partially...
