Use the map below to answer the following questions. Ages of rocks found in each of the locations are given in millions of years. For example, rocks found in the Suiko Seamount formed 59.6 million years ago, or 59,600,000 years ago. For this exercise, you will need a ruler, calculator, and brain. 1. If North on this map is “up”, describe the general plate movement history (timing and direction) from the Suiko Seamount to Loihi. 2. Calculate the average plate velocity (distance per unit time) of the Pacific Plate in centimeters per year using the eight principal islands of the Hawaiian Archipelago in the table below. From Distance Distance (cm) Time (years) Velocity (km) Hint: 1 km = Distance (cm) 100,000 cm Time( yrs) Hawaii to Maui Maui to Molokai Molokai to Oahu Oahu to Kauai Average velocity = cm/year 3. Why do you think that only the youngest volcanic formations (the cight principal Hawaiian Islands) are above sea level? • >1.0 4.9 -5.1 Aleutian 226 KAUAI Trench OAHU Suiko NIHAU 3.7 2.6 Seamount 1.8 59.6 Honolulu MOLOKAI 1.9-1.3 216 LANAIS MAUI Nintoku A 1.3 Seamount 0.43 KAHOOLAWE 4 56.2 0.8 0.38 Jingu The eight principal islands -406 Seamount 29606 of the Hawaiian Archipelago 50 100 150 km 0.15 HAWAII Seamount 55.2 1598 Koko Yuryaku 196 Guyot Seamount Midway 27.2 48.1 1580 1576 1566 1550 306 Pearl & Hermes Reef Daikakuji Seamount 20.6 42.4 Kauai Laysan 19.9 Nihoa Oahu 55.4Ojin 0.01 Loin 0.004 43.4 1203 La Perouse Pinnacle Necker hea 12.0 10.3 Niihau Lanai 1706 1606 Molokai Maui Hawaii 1503 -205 1706 1806
