sinking

what is the first step in heating our atmosphere

the sun heats the surface of the earth by radiation which travels in waves

what is the third step heating our atmosphere

this air begins to rise and it will eventually cool and begin to sink this is called convection

cool air sinks

true

high pressure is sinking air

true

higher temperature means faster moving molecules

true

low pressure is under rising air

true

lower temperature mean slower moving molecules

true

the sun indirectly heats the air in our atmosphere

true

warm air rises

true

warm air warms up the air molecules move faster

true

when air cools down the air molecules move slower
