Question

despite their similar - sounding names, the arctic and the antarctic regions have a number of different features, especially when it comes to animal life. for example, polar bears live only in the arctic, while penguins live only in the antarctic. another difference lies in the ice found in each location. the arctic region consists of ocean almost completely surrounded by land, whereas the antarctic region is a land mass surrounded by ocean. ice in the antarctic is mobile. it can float freely into warmer ocean waters, where it melts. by contrast, ice in the arctic tends to stay in cold arctic waters and grow thick. since air in the arctic tends to be dry, precipitation is rare, and snowfall is generally low. on the other hand, the air above antarctica is relatively moist, so snowfall is more common.

Explanation:

• Penguins live in the Antarctic as stated in the text.
• The Arctic is surrounded by land.
• Antarctic sea ice is mobile.
• Arctic sea ice grows thick.
• Antarctic has more common snowfall.

Answer:

Penguins live there: The Antarctic.
Is surrounded by land: The Arctic.
Sea ice is highly mobile: The Antarctic.
Sea ice is thick: The Arctic.
Snowfall is common: The Antarctic.
