Answer: D. It can melt to a depth of a few meters in summer, then refreeze in winter.
Explanation:
Permafrost is ground which remains frozen for two or more years. Permafrost consists of soil, rock and sand fused together by ice. Mostly found in areas in high altitude, the Arctic, Antarctica, it is common in periglacial environments where temperatures are below freezing

The topmost layer of permafrost can melt in summer and refreeze in winter. This thawing and refreezing produces a ground pattern called columnar joints similar to the one formed when molten lava cools.
The era of piracy began in the 1500’s and faded by the 1830’s. Their presence was consistent in the Caribbean from 1623-1638 which ended due to navies of Western Europe and North Americans combatting the pirates. Pirates were most successful from 1660-1730’s. Particularly during the 1600’s, maritime technology began innovation. Trading traffic increased, which for pirates meant more ships to ransack and give rise to their piracy. By the 1690’s, pirates began a route they named the “Pirate Round.” They would sail from the Indian to the Red Sea, searching for trade ships deploying from India. 1718 was the beginning of the end for the “Golden Age of Piracy.” Two years later, in 1720, the English captured famous pirate Jack Rackham and his two female shipmates. In 1722, the wealthiest pirate known had died. His name was Bartholomew Roberts. By 1730, this era had ended.
