Answer: The event that occurred in 1987 was the breaking away of a gargantuan iceberg from the Ross Ice Sheet in Antarctica. This event involved the separation of a large section of ice from the ice sheet and its release into the ocean, potentially posing risks to shipping and navigation.
Step-by-step explanation:
The event that occurred in 1987 was the breaking away of a gargantuan iceberg from the Ross Ice Sheet in Antarctica.
Here's a step-by-step explanation:
1. The Ross Ice Sheet is a large mass of ice that covers a significant portion of Antarctica. It is one of the largest ice sheets in the world.
2. In 1987, a gargantuan iceberg broke away from the Ross Ice Sheet. This means that a massive section of ice, known as an iceberg, separated from the main ice sheet and became free-floating in the ocean.
3. Icebergs form when glaciers or ice sheets extend into the ocean and break off due to various factors, such as melting or calving (the breaking of ice at the edge of a glacier or ice sheet).
4. The breaking away of a gargantuan iceberg in 1987 was a significant event because it resulted in the release of a massive amount of ice into the surrounding ocean.
5. The breaking away of icebergs is a natural process and occurs regularly in polar regions. However, the size and impact of this particular iceberg breaking away may have been notable due to its size or location.
6. Icebergs can pose risks to shipping and navigation as they can drift into shipping lanes and potentially collide with vessels. Therefore, the breaking away of a gargantuan iceberg in 1987 might have been of concern to maritime activities in the area.
