Where did the iceberg in the image, which Morgan and Javeon were studying, originate from?

• It was artificially created

• It broke off an Arctic ice sheet

Answer explanation

The iceberg originated from breaking off an Arctic ice sheet, as indicated by the image Morgan and Javeon were studying.

What happened to the iceberg after it broke off?

• It melted immediately

• It drifted south on ocean surface currents

Answer explanation

The iceberg drifted south on ocean surface currents after breaking off, not melting immediately.
