Why is having a scientific model of the atom important? 1.the model allows us to predict how atoms will behave in certain situations. 2.the atom is the smallest known particle in the univierse. 3.models are used to prove which scientist is correct in a debate. 4.it is impossible to predict how atoms behave in nature.

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
