Many scientists believe that the sinking lithosphere layer can't melt at this depth, but that the heat and pressure forces the water (the surface water and water from hydrated minerals) out of the plate and into the mantle layer above. The increased water content lowers the melting point of...
Did you know: Like diamonds, no two snowflakes are alike? How to Calculate Price per Carat Carat Weight x Price per Carat = Total Diamond Cost Here's how it works: If a 0.9 carat diamond is $5,500 per carat, the total diamond price would be $4,950 (0.9 x $5,500) If a 2 car...
all minerals are also rocks,diamondis the hardest rock. Rocks that contain more than one mineral can't really have a single 'hardness' rating because each of the minerals they are comprised of will have a different hardness. For example, most granite is made up of quartz, feldspar, and ...
