Question
The Galapagos Islands are part of another volcanic island chain formed by passing over a hot spot Use the figures in your textbook to determine on which tectonic plate the Galapagos Islands are found. Question #9 The Galapagos Islands are found on the plate which is traveling in the direction Find the islands of San Cristobal and Fernandina on a map of the Galapagos Islands below Question #10 Knowing the direction of plate movement, which of these two islands would you think is the younger and which is the older? Why? The Plate Tectonic story of the Galapagos is nicely presented and illustrated on a website by Dr. Robert Rothman. Please click here and read this short article. Then look here and look at this one. From the information in these articles, we can calculate the rate of movement for this particular tectonic plate. Question #11 By reading the articles above, we find that the ages of the islands of San Cristobal and Fernandina are and Using the map we linked to above, the distance between these two islands isk m. Question #12 How fast is this plate moving? Show your work. Give your answer in centimeters per year. Question #13 How long will it take before the Galapagos Islands to go down the trench off of South America's west coast? (You will need to look up some distances online or on a map in order to calculate this) GA L A P AGO S Santiago O ISLAN D S Santa Cruz San Cristobal IsabelaExplanation / Answer
9. The galapagos islands are found on Nazca plate which is moving in the direction of east-southeast direction and its speed is a bit more than the average speed of plate movement and its speed is aroun 5cm/year.
10. The older islands are San Cristobal and Santa Cruz while the younger one are Santiago and Fernandina with Fernandina being the younges and San Cristobal is the oldest out of the four.
11. The link is unavailable hence can't say about the part.
12. The plate is moving at an approx. speed of 5cm/year this can be seen by the formation of Andes Mountains on the western coast of South America caused by the collision of Nazca plate with South American Plate.
13. South America west coast is around 1000 kilometer from galapagos islands and the speed of plate is 5cm/year.
1000 kilometer = 1000 x 1000 x 100 cm
time = 100,000,000/5
= 20,000,000 years
