Suppose that the two elements A (represented by triangles) and B (represented by squares) form a molecular compound with the molecular formula A2B, and that two other elements, C (represented by circles) and D (represented by diamonds), form an ionic compound with the formula CD. Draw a molecular-level view of each compound.

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
