Which geological outcome results when mantle plume weakening occurs under Iceland?

💡 Explanation

A smaller mantle plume leads to decreased magma production and spreading at the Mid-Atlantic Ridge due to thermal buoyancy reduction weakening the upwelling; therefore, lower spreading, rather than increased glacial rebound after volcanic loading changes, is the observed effect rather than transform ruptures.
