Lower Mantle Concept & Composition: What is the Lower Mantle?

WebMantle behaves as a visco-elastic solid everywhere beneath the crust. Due to extreme high pressure below the crust, mantle is a solid that flows at a time scale of million of years. … WebMantle. The mantle is almost entirely solid rock, but it is in constant motion, flowing very slowly. It is ultramafic in composition, meaning it has even more iron and magnesium than mafic rocks, and even less silica. Although the mantle has a similar chemical composition throughout, it has layers with different mineral compositions and different physical … can i bring alcohol on cruise ship
