As per the scale given in the bottom right corner of the map, the distance between the various islands is calculated in the table below. For the difference in the ages of the islands the, the absolute age of one island is subtracted from the absolute age of the second island.
Islands | kilometres | Centimetres | Difference in age between two islands |
Hawaii and Maui | 125 | 125 x 105 | 1 x 106 |
Maui and Molokai | 82 | 82 x 105 | 1 x 106 |
Molokai and Oahu | 105 | 105 x 105 | 1.2 x 106 |
Oahu and Kauai | 175 | 175 x 105 | 1.9 x 106 |

Consider the age of the various Hawaiian Islands given below in millions of years. Remember, the formation of the Hawaiian Islands reflects: 1) the movement of the Pacific plate, and 2) stationary volcanic hotspot activity over time. Which direction is the Pacific plate currently moving? Maps are plan or bird's eye views of the earth's surface. Here, the top of the figure is north, and the bottom of the figure is south. The left side of the figure is west,...
Volcanic Hotspots and Seafloor Spreading The figure below is a map of the volcanic islands and seamounts (submerged volcanoes) that form the Hawaiian Islands and the Hawaiian-Emperor Chain. These were formed by a "hot spot" - a relatively stationary hot plume that rises through the earth's mantle and melts part of the overriding plate. Table 1 shows a selection of some of these volcanoes with regard to their age and distance from the active hot spot location. The change in...
