Most icebergs are formed in the waters of the world's polar and subpolar regions. These are the regions in and around the North and South Poles. Icebergs melt as they encounter warmer ocean breezes closer to the equator. This happens with most, but not all, icebergs. One record-setting iceberg managed to travel further from the frigid waters near the poles than any other iceberg has been known to travel. In 1894, an iceberg broke off from Antarctica in the south and began moving slowly northward. It eventually left the very cold water near the pole and entered warmers waters. This unusual iceberg managed to get amazingly close to the equator. It was observed at a latitude of about 26 degrees south of the equator. This is on the same latitude as Rio de Janeiro, Brazil, which is famous for its comfortably warm waters and weather throughout the year.
The subject of the passage is
Correct Answer
C. One unusual iceberg
Explanation
The subject of the passage is one unusual iceberg. The passage discusses how most icebergs are formed in the polar and subpolar regions, but this particular iceberg broke off from Antarctica and traveled further northward than any other iceberg.
