(look at the minerals in the linked picture)
both diamond and coal are formed by changes in pressure and temperature below the earth's surface. which of these is a step in the formation of the minerals?

a) atoms break up in extreme heat
b) atoms are rearranged in materials
c) atoms combine in water to form solids
d) atoms of magma cool after a volcanic eruption

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
