World’s largest iceberg breaks off frozen edge of Antarctica

The video discusses an iceberg calving from the Ronne ice shelf in Antarctica, highlighting its size and comparisons to Mallorca and New York City. It explains that the iceberg's melting won't raise sea levels as it was part of a floating ice shelf. The video also addresses climate change, noting that this iceberg's formation isn't linked to it, but warns of significant sea level rise if Antarctica's ice sheet melts.

What is the size of the iceberg that calved from the Ronne ice shelf compared to?

• The state of Texas

• The country of Japan

• The city of London

• The island of Mallorca

Why does the melting of this iceberg not contribute to sea level rise?

• It is made of freshwater

• It is melting too slowly

• It was already floating

• It is too small

What is the main difference between icebergs and glaciers in terms of their impact on sea levels?

• Icebergs are larger

• Glaciers are found only in Antarctica

• Glaciers are made of saltwater

• Icebergs float while glaciers rest on land

According to the transcript, what is not believed to have caused the formation of this iceberg?

• Ocean currents

• Climate change

• Volcanic activity

• Human intervention

If Antarctica's entire ice sheet were to melt, by how much could sea levels potentially rise?

• 100 feet

• 190 feet

• 50 feet

• 10 feet
