Why are polar regions experiencing rapid climate change?
Due to global warming caused by human activities.
What is the term for the area between the tundra and ice caps in the polar regions?
The subpolar region.
What adaptations do polar animals have to survive in their harsh environments?
Thick blubber or fat layers, counter-current heat exchange systems, and ability to swim.
What is the significance of polar regions for climate regulation?
The ice and snow reflect sunlight, helping to regulate global temperatures.
What are some human activities that threaten the tundra and polar regions?
Oil and gas exploration, mining, pollution, and climate change.
