Carbon dioxide is commonly found as a solid (dry ice) or a gas (carbon dioxide gas). jeff's teacher asked him to draw models to show the motion of carbon dioxide molecules that make dry ice different from carbon dioxide gas. describe what was correct and what might be improved about jeff's models in showing the motion of the carbon dioxide molecules that make dry ice different from carbon dioxide gas

Compare and contrast physical changes with chemical changes.

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
