How does charging by conduction compare with charging by induction? a) a charged object is needed in conduction but not in induction. b) two neutral objects are needed in conduction but not in induction. c) objects must touch in induction but not in conduction. d) oppositely charged objects form in induction but not in conduction.

D) Oppositely charged objects form in induction but not in conduction.

Induction: is the method of charging an object by bringing a charged object close to it without touching whereas Conduction: is the method of charging an object by touching it with a charged body. The charged body losses the charge and become neutral. The uncharged body gains the charge and become charged.

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.​

does anyone know or what?
