Explanation:
The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.
This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.
