If you put a steamy cup if coffee in refrigerator, it wouldn't immediately turn cold. Likewise, if the sun simply turned off , the earth would stay warm - at least compared with the space surrounding it - for a few million years. But we surface dwellers would feel the chill much sooner than that.within a week, the average global surface temperature would drop below 0degree F. In a year, it would dip to -100degrees. The top layers of oceans would freeze over
Although some microorganisms living in the earths crust would survive, photosynthesis would halt immediately, and most plants would die in few weeks , and animals who eats plants would die off quickly
