I'll give you a medal : )
a scientist heats a sealed flexible container full of helium gas. what will most likely happen to the container as the gas absorbs heat?

it will shrink because the helium atoms will break apart into smaller pieces.

it will expand because the helium atoms will get larger.

it will expand because the helium atoms will move more quickly and get farther apart.

it will shrink because the helium atoms will lose energy as heat and move closer together.

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
