## TL;DR

The Arctic and Antarctic are both polar regions, but they are not geographic mirrors. The Arctic is an ocean region surrounded by northern continents, while Antarctica is a continent surrounded by the Southern Ocean. Antarctica is governed through a treaty system centered on peaceful use and scientific cooperation.

## Core Explanation

The two regions differ in geography, ice structure, ecology, and governance. The Arctic includes sea ice, surrounding land, and human communities; Antarctica is dominated by a continental ice sheet and scientific stations. For live conditions such as sea-ice extent or permafrost emissions, current monitoring data should be checked rather than inferred from this static overview.
