If mass is conserved during a nuclear reaction, then the mass of the daughter elements will have decreased from that of the parent element the total atomic mass of the daughter elements should equal that of the parent element the mass of the daughter elements will have increased by as many protons as times decayed from the parent element the mass of the parent elements will have split evenly into two identical daughter elements

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
