Question

which type of ice melt will have the greatest impact on sea level rise? permafrost land ice all of the above will have an equal impact sea ice

Explanation:

Land ice, such as glaciers and ice sheets on land, when melting, directly adds water to the oceans. Permafrost melting mainly affects ecosystems and releases greenhouse gases rather than directly contributing much to sea - level rise in the short - term. Sea ice is already floating, and according to Archimedes' principle, when it melts, it does not cause a significant rise in sea levels (similar to an ice cube melting in a glass of water).

Answer:

Land ice
