Antarctica Exploration Quiz

What is the primary reason Antarctica is covered in ice today?

• It has always been covered in ice.

• It is a floating ice sheet.

• Glaciers started forming 38 million years ago.

• It is located at the North Pole.

How do scientists use radio waves to study Antarctica's landscape?

• By heating the ground with radio waves.

• By using radio waves to communicate with penguins.

• By bouncing radio waves off the ice to map the terrain.

• By melting the ice with radio waves.

What did scientists discover about Antarctica's past landscape?

• It was always a flat, icy desert.

• It was once covered by a tropical rainforest.

• It had rivers that carved valleys between mountains.

• It was a volcanic island.

What is one reason water remains liquid beneath Antarctica's ice?

• The water is mixed with salt, lowering the freezing point.

• The pressure from the ice is extremely high.

• The water is heated by volcanic activity.

• The ice is not thick enough to freeze the water.

What is a unique feature of some freshwater rivers found under Antarctica's ice?

• They are filled with saltwater.

• They flow downhill like typical rivers.

• They are completely frozen solid.

• They can flow uphill due to pressure.

What is the Madrid Protocol's role in Antarctica?

• It permits fishing in Antarctic waters.

• It allows commercial mining in Antarctica.

• It encourages tourism in Antarctica.

• It declares Antarctica a nature sanctuary for scientific research only.

What is one method used to indirectly sample Antarctica's resources?

• Drilling through the ice to extract minerals.

• Studying rocks in regions that were once connected to Antarctica.

• Collecting ice cores from the surface.

• Using submarines to collect samples from the ocean floor.

What is one challenge of directly sampling Antarctica's resources?

• The ice is too thin to support drilling equipment.

• The Madrid Protocol restricts invasive sampling.

• There are no valuable resources to sample.

• The weather is too warm for ice drilling.

What type of life has been found beneath Antarctica's ice?

• Only microbial life.

• Only fossils of ancient plants.

• Only penguins and seals.

• Both microbial and macroscopic life, like crustaceans.

What is one theory about how life sustains itself under Antarctica's ice?

• Life forms feed on penguins.

• Volcanic heat provides energy.

• Nutrients are brought in by ocean currents.

• Photosynthesis from sunlight penetrating the ice.
