Which geographic deformation results from mantle plume convection?

💡 Explanation

Mantle plumes transport heat to the lithosphere, causing crustal melting. Extensive flood basalt formations occur because decompression melting and magma production overwhelm surface erosion, therefore large basalt plateaus result, rather than isolated volcanoes from subduction.
