The formation of the Hawaiian Islands.
Explanation:
A modern process that is believed to be similar to the way crusts formed before the advent of plate tectonics about million of years ago is the formation of the Hawaiian Islands.
The Hawaiian Island is a series of volcanic Island which forms as result of volcanic activities on the oceanic plate.
- Hawaiian Islands forms from a hotspot that supplies the ocean floor with sufficient magma as it rides.
