Final answer:
The correct matches link Gondwana to a supercontinent, an archipelago to a chain of islands, an ice shelf to covering much of Antarctica, and an atoll to an island made of coral.
Step-by-step explanation:
To match the terms in column 1 to the definitions in column 2, we can start with what we know about each term. Based on your references and the context provided, here are the correct matches:
- 1) Gondwana - A supercontinent that was part of Pangaea, which later split into several continents we know today, primarily in the Southern Hemisphere.
- 2) Archipelago - A chain of islands, such as the Greater Antilles in the Caribbean Sea.
- 3) Ice shelf - A thick platform of ice that covers much of Antarctica's coastlines.
- 4) Atoll - A ring-like coral island or string of small islands surrounding a lagoon, often found in tropical ocean waters.
- 5) An island made of coral - Corollary to the definition of an atoll, this can describe any island primarily composed of coral structures.
- 6) A chain of islands - Synonymous with an archipelago.
- 7) Covers much of Antarctica - This is referring to the ice shelf as it is a large extension of ice over the ocean at the continent's edge.
- 8) A supercontinent - This could refer to Gondwana as part of the former supercontinent Pangaea before it separated into smaller continents.
Through examining geographical features and paleontological evidence, we can piece together past supercontinents and understand how current landscapes, such as archipelagos, atolls, and ice shelves, are formed and interact with their environment, including the role they play in ecosystem services.
