If ice streams were to collapse, they could raise sea levels by several metres.
Step-by-step explanation of the answer:
To answer a fill in the blank question, you have to look for clues that tell you the answer in the extract. 🔑
- Sometimes, the clues are context clues, which are words or sentences that help you figure out the meaning of an unknown word. For example, “They are responsible for draining a significant portion of the Antarctic ice sheet.”
- Other times, the clues are grammar clues, which are rules or patterns that help you choose the correct word form or part of speech. For example, “If ice streams were to collapse, they could raise _______ levels by several metres.” (The blank should be filled with a noun.)
- In this extract, the clue is a context clue, which means we have to use our comprehension skills to find the answer. 🧐
- We know that this extract is about Antarctica and its ice streams, which are rivers of ice that flow into the ocean. We also know that if these ice streams were to collapse, they would release a large amount of water into the ocean. Therefore, we can infer that if ice streams were to collapse, they could raise sea levels by several metres. 🌊
Therefore, based on this clue, we can fill in the blank with the word “sea”. ✍️
