a) Mention one similarity.
​

Answer 1

Answer:

Travel to the ends of the earth—literally—and discover the polar ocean basins. Both the Arctic Ocean and the Southern Ocean are defined by ice and dramatic shifts between endless day and endless night. The environments at the poles are some of the harshest on Earth—yet animals have found ways to survive there against the odds.

Although both are icy and frigid, the poles are actually more different than you might expect. In the northern polar region, the water and ice of the Arctic Ocean are surrounded by land. Depending on the season, much or all of the Arctic Ocean is covered by a layer of sea ice, ranging in thickness from a few inches to over six feet, which is always shifting as it floats on the ocean's surface. On the adjacent land, communities of native peoples have thrived for thousands of years by adapting to life along the edge of the ice.

Meanwhile, the southern polar region has the opposite geography, with the huge landmass of Antarctica surrounded by the turbulent Southern Ocean. All but one or two percent of Antarctic land is covered by glaciers, some of which are more than 15,000 feet (4,700 meters) thick. In the Antarctic, the only human residents are scientists and technicians at isolated research stations whose food must be shipped in by boat.
