100

the space around us, we are surrounded by lots of tiny and invisible air particles, which are constantly moving

Air 

200

instrument that measures air pressure

barometer

300

this happens to air pressure as altitude increases

decreases

400

as the density of air increases, the air pressure does this

decreases

500

air has mass, it also exerts pressure, called air pressure
