Antarctic Airstrip: Unlocking the Secrets of the Frozen Continent

Antarctica's frigid climate limits human habitation to scientific bases. Its role in Earth's climate system is crucial, with ice sheets storing vast amounts of fresh water. Scientists study melting ice's impact on sea levels and climate. Access to Antarctica is challenging, limited to the southern summer. A new airstrip near Australia's KC base improves access, allowing shorter visits. An Airbus A319 can now make the round trip from Hobart without refueling. The airstrip is designed to reflect sunlight, preventing uneven melting. The first flight was celebrated by research teams and politicians.

Why is Antarctica considered crucial in the Earth's climatic system?

• Because it is a major source of fossil fuels.

• Due to its large population of penguins.

• Due to its role in storing fresh water and affecting sea levels.

• Because it is a popular tourist destination.

What do the air bubbles trapped in Antarctica's ice reveal?

• The mineral composition of the ice.

• An accurate record of the atmosphere and prehistoric climate changes.

• The history of human habitation in Antarctica.

• The types of animals that lived in Antarctica.

What is a major challenge for scientists wanting to collect data in Antarctica?

• The presence of dangerous wildlife.

• The limited window for voyages during the southern summer.

• The high cost of living in Antarctica.

• The lack of internet connectivity.

What recent development has improved access to Antarctica for scientific teams?

• The construction of a new research station.

• The introduction of a new icebreaker ship.

• The carving of a flat airstrip near Australia's KC Antarctic base.

• The establishment of a permanent settlement.

How does the new airstrip near Australia's KC Antarctic base help in maintaining its surface?

• By using solar panels to generate heat.

• By resurfacing with packed snow to reflect sunlight.

• By painting it with a special reflective paint.

• By covering it with a layer of sand.
