Which is an example of a heterogenous mixture? a) gasoline b) diet soda c) grape juice d) flour and water

D flour and water

Explanation:  A heterogeneous mixture is a mixture that is not uniform in composition which means the mixture can be separated from one another. The only answer choice that you have put up there that is of two things being mixed together and that's flour and water

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.​
