Atoms to Matter with Convection Currents

let us see small things

let us see large things

make things look bigger

animals

made of atoms

matter

make everything with mass and volume

can be seen with just our eyes and with microscopes

make molecules and molecules make matter

2 or more atoms

the tiniest particle we know

molecules move slower when hot

molecules move faster when hot

molecules contract when hot

sinks

fills in empty space

mostly moves left to right

rises

rises

falls

moves slowly

is very dense

Cold rises. Hot sinks.

It explains why the floor is colder than the ceiling.

Heat rises. Cold Sinks.

It explains why we have water molecules.

is a convection cell

explains why we have deserts

explains why we have rain forests

rises at the equator

sinks (falls) about 30 degrees north and south of the equator
