Define scalar and vector quantities

Vectors: have magnitude and direction

Scalers: have only magnitude

-They are different because scalers don't have direction like vectors do

-they are alike because they both have magnitude

Hope this helps!

I just learnt about this, so that was great timing! :)

explanation:

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

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

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.​
