When consumption or production of a product has a harmful side effect that is borne by people not directly involved in the market exchange for that product, the side effect is called a(n):

An external cost.

Explanation:

An external cost is the cost borne upon by a third party, maybe an individual, firm or community as a result of a market exchange for a product which they are not directly involved in. And this can occur in both production and consumption.

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.​
