A

T

29

F

31
Q

T/F temperature inversions occur when cold air gets trapped beneath warm air

A

T

32
Q

How does the earth heat up?

A

Convection causes the air molecules right above the surface to heat up. this causes warm air rot mix in the atmosphere. radiation from that sun is what warms the ground

33
Q

how does the earth cool off at night?

A

at night the cold air mixes with the warm air which causes the air to cool.
