How does sea ice form in the Arctic and Antarctic regions?

• Sea ice forms in the Arctic and Antarctic regions due to volcanic activity.

• Sea ice forms in the Arctic and Antarctic regions because of high air pollution levels.

• Sea ice forms in the Arctic and Antarctic regions when the surface water of the ocean freezes due to the extremely cold temperatures in these areas.

• Sea ice forms in the Arctic and Antarctic regions as a result of excessive sunlight exposure.

What is the main impact of climate change on the Arctic and Antarctic regions?

• Increase in biodiversity

• Decrease in sea levels

• Rapid melting of ice caps and glaciers

• Expansion of polar bear populations

How have marine life adapted to survive in the extreme cold of the polar seas?

• Marine life in polar seas have adapted by hibernating during the winter months

• Marine life in polar seas have adapted by using solar panels to generate heat

• Marine life in polar seas have adapted by developing thick layers of fat or blubber, having a lower metabolic rate, possessing antifreeze proteins, and having specialized body structures to retain heat.

• Marine life in polar seas have adapted by growing wings to fly away from the cold

Which flightless bird species is commonly found in the Antarctic region?

• Snowy Owl

• Antarctic Albatross

• Arctic Tern

• Emperor Penguin

What is a polynya and how does it affect the surrounding marine ecosystem?

• A polynya is an area of open water surrounded by sea ice. It affects the surrounding marine ecosystem by providing a source of nutrients and a habitat for marine life.

• A polynya is a type of fish that preys on marine life, leading to a decrease in biodiversity.

• A polynya is a man-made structure used for fishing, disrupting the natural balance of the marine ecosystem.

• A polynya is a weather phenomenon that causes extreme storms in the surrounding marine ecosystem.

What is the main threat to penguins in the polar regions?

• Overfishing

• Alien invasion

• Oil spills

• Climate change

How do polar bears hunt for food in the icy waters of the Arctic Ocean?

• By hunting in packs like wolves

• By scavenging for food on land

• By waiting near breathing holes in the ice for seals to surface

• By using fishing nets to catch fish
