As the North American Platter and the Juan de Fuca Platter slide gone-by each other on a raze flatten, rubbing fruits the passion to geneadmonish magma. 2. As the Juan de Fuca platter is rifted aside, inferior encroachure at the rift fruits magma that feeds the volcanoes at the Cascade Range. 3. Subduction of the Juan de Fuca Platter inferior the North American Platter brings rolls from the deep pedestal and marine refuse to profunditys where inequitable running ensues due to the growthd clime and the wave of introduce. 4. Migration of the North American Platter aggravate a hot disfigurement is lawful for the Cascade Range volcanoes. Part 2- Google Earth The exercises that prosper use Google Earth. For each inquiry (or set of inquirys) gone-bye the colonization that is ardent into the “fly to” box. Criticize each colonization at multiple eye altitudes and differing amounts of tilt. For any appraisements use the magistadmonish machine, this can be accessed by clicking on the magistadmonish icon aloft the shadow. Google Earth: Hawaiian Islands Fly to Hawaii. Please criticism the exception on Hotspots and the Hawaiian Islands in the Lab manual and in the ace notes. Rocks bear been dated on each of the Hawaiian Islands and their ages are as prospers: Big Island- 0 (active), Maui – 1.1 darling, Kauai- 4.7 darling, Nihoa (23 03 32.79N 161 55 11.94W)- 7.2 darling years 28. Consider the ages and positions of the islands listed aloft parallel aftercited a while what you recognize environing platter tectonics and hotspots. In what public bearing is the Pacific Platter affecting? 1. Northwest 2. Southeast 3. Northeast 4. Southwest 29. How firm was the Pacific platter affecting during the conclusive 1.1 darling years betwixt the construction of the Big Island and Maui in cm/year? 1. ~5 cm/year 2. ~10 cm/year 3. ~15 cm/year 4. ~20 cm/year 30. How firm was the Pacific platter affecting from 7.2 darling years ago to 4.7 darling years ago betwixt the construction of Kauai and Nihao in cm/year? 1. ~5 cm/year 2. ~10 cm/year 3. ~15 cm/year 4. ~20 cm/year 31) Criticize the headings of the appraisements that you took for the preceding two inquirys. The headings betray the bearing the Pacific Platter is affecting aggravate the hot disfigurement. How does the bearing of disturbance of the Pacific Platter during the conclusive 1.1 darling years dispute from bearing of affectment betwixt 4.7 and 7.2 darling years ago? The bearing of platter affectment in the conclusive 1.1 darling years________. 1. professions no modify 2. has grace advance northerly 3. has grace advance southerly 32) Zoom out and criticize the dozens of sunken volcanoes out gone-by Nihoa, designated the Emperor Seamounts. As one of these momentary islands on the Pacific Platter affects off the hotdisfigurement it graces lazy, or extinct, and the island initiates to diminish as it and the surrounding tectonic platter calm down. The hurry the islands are diminishing can be estimated by measuring the disputeence in refinement (tilting the shadow helps to perceive the leading refinement) betwixt two islands and dividing by the disputeence in their ages (this statute assumes the islands were a congruous extent when they were free). Using Maui and Nihoa, how firm are the Hawaiian Islands diminishing? 1. ~0.05 cm/year 2. ~0.5 cm/year 3. ~5 cm/year 4. ~10 cm/year 33) Using the hurry you conducive in the preceding inquiry (and ignoring potential modifys in sea raze), when conquer the Big Island of Hawaii diminish underneath the demeanor of the deep? 1. ~650,000 years 2. ~1.2 darling years 3. ~8 darling years 4. ~13 darling years 34) Criticize the Emperor Seamounts and mention that it is a uniform tie that reaches far north to the Aleutian Islands of Alaska. Using a hurry halfway betwixt that which you conducive in inquirys 29 and 30, reckon the age of the oldest (furthest North) seamount in the Emperor Seamounts?
