Quizplus · Accepted Answer

Ancient coal beds can be found in Antarctica because at one time the climate of Antarctica was mild enough to support swamplands. During the Carboniferous period (about 360-300 million years ago), Antarctica was located closer to the equator and had a warmer climate. Plants thrived in the swampy environment, and over time, the organic material from the plants formed coal beds. As Antarctica moved to its current position in the Southern Hemisphere, the coal beds were buried under ice and preserved.
