What is the significance of Antarctica in understanding Earth's history?
Antarctica holds geological records, such as ice cores with carbon data, that help us study Earth's past, present, and future.
What was Gondwana?
Gondwana was a giant southern supercontinent that existed 650 million years ago, centered around present-day Antarctica.
Why is climate change a significant concern in Antarctica?
Antarctica's ice cores contain carbon records that show climate change effects, and its ecosystem is sensitive to environmental changes.
What role does the 'Students on Ice' program play?
It educates high school students about environmental issues by providing firsthand experiences in Antarctica.
How does the simple ecosystem of Antarctica help in environmental studies?
Its simplicity allows scientists to observe how small environmental changes can have significant impacts.
What is the importance of phytoplankton in Antarctica?
Phytoplankton are crucial for the Southern Ocean's food chain and play a key role in the global carbon cycle.
