What are the main polar regions?

The main polar regions are the Arctic, surrounding the North Pole, and the Antarctic, surrounding the South Pole. Both are defined by their extreme cold, ice cover, and unique ecosystems.

Why are polar regions important for global climate?

Polar regions play a crucial role in regulating global climate by reflecting sunlight (albedo effect) and influencing ocean currents. Their melting ice significantly contributes to global sea-level rise.

What unique wildlife inhabits the polar regions?

Unique wildlife includes polar bears, seals, walruses, and Arctic foxes in the Arctic. Antarctica is famously home to various penguin species, whales, and seals, adapted to extreme conditions.

How are polar regions affected by climate change?

Climate change causes rapid warming, leading to accelerated ice melt, sea-level rise, permafrost thaw, and significant habitat loss for polar species, impacting global weather patterns and ecosystems.

What is the difference between Arctic and Antarctic ice?

Arctic ice is primarily sea ice floating on the ocean, though land ice exists (e.g., Greenland). Antarctic ice is predominantly a massive ice sheet covering a continental landmass.
