Fresh grapes contain a very large amount of water. Exposure to the sun dries the grapes; the water evaporates out of them. This is the process of making raisins.

You only need one.
osmosis takes place
Grapes dried in the sun become raisins.

Yes, the Sun will eventually shrink. It is estimated to shrink in about 5 billion years from now so we would have moved on or evolved by that time anyway.
Let them sit out in the sun
Raisins are brown because they are grapes that have been dried out in the sun. Usually, the "brown raisins" start out as purple grapes. The white ones turn a bit lighter brown, not the dark brown as most of us are accustomed to from SunMaid and such, so they start out purple. And then, the sun's rays heat and dry out the grapes, and they shrivel up, creating that pruny finish - like how your fingers are after they've been in water for a large amount of time. Just like our skin, grapes shrivel up when they dry out. Also, just like our skin, it loses it's color as it dries out. The vibrant purple grape is changed into a dark brown, shriveled up grape - thus creating a raisin! IN SUM: The sun's "heating/drying the grapes" process discolors the grapes.Hope you found this useful. :) Best of wishes! Xx
because the sun's rays hit it
in the sun light
Grapes, they're dried by the sun.
Most of the time, they would dry them in the nice, hot sun. then they are called SUN DRIED RAISINS!
