Read the passage: 'Glacial rebound, also known as post-glacial isostatic adjustment, causes coastal land in northern Sweden to rise relative to sea level by nearly one centimetre per year as the crust recovers from the weight of Ice Age ice sheets.' What causes this upward crustal movement?
Answer and explanation
Correct answer: B. The gradual rebound of the Earth's crust after ice removal
- Step 1: The text explains that the crust is rising as it recovers from the immense weight of melting Ice Age ice sheets. Step 2. Match with the gradual rebound of the crust following ice removal. Answer: The gradual rebound of the Earth's crust after ice removal. Why not the others: Magma subduction is not the cause; modern ice is retreating, not accumulating; wave erosion does not cause regional crustal uplift.
