Given : Airplane is 0.68 kilometers long

We know that :

⊕   1 km = 1000 meters

⊕   1 m = 1000 millimeters

⇒   1 km = (1000 × 1000) millimeters

⇒   0.68 km = (0.68 × 1000 × 1000) millimeters

⇒   0.68 km = 680,000 mm

Airplane is 680,000 millimeters long

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.​
