Magnesium (mg) is a valuable metal used in alloys, in batteries, and in chemical synthesis. it is obtained mostly from seawater, which contains about 1.3 g of mg for every kilogram of seawater. calculate the volume of seawater (in liters) needed to extract 8.0 x 104 tons of mg, which is roughly the annual production in the united states. (rho seawater = 1.03 g/ml).

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
