The Arctic Circle is located at 66.5 degrees north latitude and experiences continuous daylight during the summer months due to the Earth's tilt and rotation.

The Antarctic Ice Sheet is the largest ice sheet on Earth, covering an area of approximately 14 million square kilometers.

The Antarctic is home to the largest population of emperor penguins, with colonies found along the coastlines and sea ice.

Glacial retreat refers to the accelerated melting and shrinkage of ice sheets and glaciers in response to climate change.

The Arctic is experiencing the most significant sea ice loss due to climate change, leading to rising sea levels and changes in global weather patterns.

Tundra is the term used to describe the unique ecosystem found in polar regions, characterized by extreme cold, limited sunlight, and sparse vegetation.

The Arctic is home to the largest population of polar bears, with populations found in various coastal and sea ice habitats.

Polar Amplification refers to the phenomenon where polar regions experience more rapid warming compared to other parts of the globe due to various factors, including ice-albedo feedback and changes in atmospheric circulation.

The Dry Valleys of Antarctica are located in the McMurdo Dry Valleys region of Antarctica and are characterized by their extreme aridity and lack of surface water.

Iceberg Calving refers to the process by which large pieces of ice break off from glaciers or ice sheets and drift into the ocean.

The Arctic is home to the largest ice cap in the Northern Hemisphere, located in the Canadian Arctic Archipelago.

Polar Adaptations refers to the unique adaptations that polar organisms have developed to survive in extreme cold and harsh conditions, such as thick fur, blubber layers, and specialized metabolic processes.

The Arctic is home to the largest population of walruses, with populations found in various coastal and sea ice habitats.

Glacial Retreat refers to the phenomenon where ice sheets and glaciers lose mass and thickness due to melting and sublimation, leading to changes in sea level and global climate.

The Arctic is home to the largest population of reindeer, with populations found in various tundra and forest habitats.
