Homework 2 Plate Motions from Hotspot Tracks (The Hawaiian Island - Emperor Seamount Chain) and Ocean Crust Ages (30 points) EAPS 10000 Y01 Planet...

Examine map on the attached Figure and Figure 5.26, L&T, 2014 (Figure 5.22, L&T, 2011). Note the trend of the Hawaiian Island chain and the continuation – the Emperor Seamounts. The top of the map is to the North. From the alignment of islands with increasing ages (from 0 to 43 million years), what direction has the plate moved over the hotspot? (Notice that the apparent direction of plate motion was considerably different prior to about 43 million years ago.) Circle the closest direction (just circle the letters corresponding to the correct direction) from the list of directions given below. (The compass directions are abbreviated, for example, NNE = North-Northeast, or half way between North and Northeast or an azimuth of 22.5°. You should be able to just estimate the correct direction from the trend of the islands shown on the map, but you may find a protractor useful if you're not familiar with directional information.)Compass direction:
