since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
