Hawaii island chain,topographical map. Elevation is colour-coded. On land,low-lying areas are green,with yellow,orange and red indicating increasing elevation. In the ocean,shallow areas of continental shelf are turquoise,with deeper blues showing deeper regions. The Hawaiian island chain stretches for some 2400 kilometres northwest of Hawaii (the largest island). This island contains two huge volcanoes,Mauna Kea and Mauna Loa,which stand over four kilometres high. The chain formed as the Pacific tectonic plate slowly moved northwestwards over a stationary hotspot. The hotspot is a region where hot mantle material erupts through the crust,forming volcanoes | |
