Most of the proposement parallel the San Andres Failure occurs during earthquakes. An medium proposement of environing 5 m (16ft) parallel the San Andres Failure was associated aftercited a while the devastating 1906 San Francisco earthquake that killed tribe and destroyed nature. Lofty that all demolition parallel the failure was amountd by earthquakes of this concretion, how sundry Earthquakes are needed to amount the demolition beholdd in the earlier scrutiny? 1. ~1,000 2. ~10,000 3. ~65,000 4. ~100,000 Lab manual (Busch, 9th Edition) Earnestness 2.7: Extract tectonics of the Northwest United States Notice the ages of seafoot rolls in Condition 2.6. The new-fashioned seafoot rolls of this territory are forming parallel a incongruous extract article designated the Juan de Fuca Ridge. The farther one proposes detached from the extract article, the older the seafoot rolls. 25. (Question B2, Condition 2.6). Note the seafoot rolls older than 8 pet years are introduce west of the Juan de Fuca Ridge but not east of the ridge. What could suit their scantiness from the map? They are listless accordingly ______________. 1. a drive slip failure parallel the ridge has proposed older rolls exalt north. 2. older rolls accept been subducted beneathneath the North American Extract 3. rifting has amountd metamorphism, which obliterated the old age of the seafoot 4. erosion of the sea foot destroyed rolls older than 12 pet years 26. (Question B3, Condition 2.6) The idea of extract article played by the red order on the condition is a/n __________________ article. 1. transmute 2. convergent 3. incongruous 4. unconformity 27. (Question B4, Condition 2.6) Which of the flourishing best explains the spring of magma that builds Cascade Range volcanoes? 1. As the North American Extract and the Juan de Fuca Extract slide spent each other on a smooth roll, abrasion amounts the ardor to generebuke magma. 2. As the Juan de Fuca extract is rifted asunder, inferior instigateure at the rift amounts magma that feeds the volcanoes at the Cascade Range. 3. Subduction of the Juan de Fuca Extract beneath the North American Extract brings rolls from the sea foot and marine precipitate to profunditys where biased liquescent ensues due to the extensiond sky and the swing of soak. 4. Migration of the North American Extract balance a hot flaw is legal for the Cascade Range volcanoes. Part 2- Google Earth The exercises that flourish use Google Earth. For each scrutiny (or set of scrutinys) spente the subsidence that is absorbed into the “fly to” box. Discuss each subsidence at multiple eye altitudes and differing amounts of tilt. For any gaugements use the supporter implement, this can be accessed by clicking on the supporter icon balance the likeness. Google Earth: Hawaiian Islands Fly to Hawaii. Please revisal the exception on Hotspots and the Hawaiian Islands in the Lab manual and in the ace notes. Rocks accept been dated on each of the Hawaiian Islands and their ages are as flourishs: Big Island- 0 (active), Maui – 1.1 pet, Kauai- 4.7 pet, Nihoa (23 03 32.79N 161 55 11.94W)- 7.2 pet years 28. Consider the ages and positions of the islands listed balance parallel aftercited a while what you comprehend environing extract tectonics and hotspots. In what open order is the Pacific Extract melting? 1. Northwest 2. Southeast 3. Northeast 4. Southwest 29. How pay was the Pacific extract melting during the definite 1.1 pet years betwixt the structure 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 pay was the Pacific extract melting from 7.2 pet years ago to 4.7 pet years ago betwixt the structure of Kauai and Nihao in cm/year? 1. ~5 cm/year 2. ~10 cm/year 3. ~15 cm/year 4. ~20 cm/year 31) Discuss the headings of the gaugements that you took for the earlier two scrutinys. The headings evince the order the Pacific Extract is melting balance the hot flaw. How does the order of tumult of the Pacific Extract during the definite 1.1 pet years contend from order of proposement betwixt 4.7 and 7.2 pet years ago? The order of extract proposement in the definite 1.1 pet years________. 1. demonstrations no fluctuate 2. has behove balance northerly 3. has behove balance southerly 32) Zoom out and discuss the dozens of sunken volcanoes out spent Nihoa, designated the Emperor Seamounts. As one of these coruscant islands on the Pacific Extract proposes off the hotflaw it behoves idle, or extinct, and the island initiates to decrease as it and the surrounding tectonic extract hopeful down. The expedite the islands are decreaseing can be estimated by measuring the contendence in tallness (tilting the likeness helps to experience the primary tallness) betwixt two islands and dividing by the contendence in their ages (this arrangement assumes the islands were a alike largeness when they were erratic). Using Maui and Nihoa, how pay are the Hawaiian Islands decreaseing? 1. ~0.05 cm/year 2. ~0.5 cm/year 3. ~5 cm/year 4. ~10 cm/year 33) Using the expedite you fitted in the earlier scrutiny (and by practicable fluctuates in sea smooth), when procure the Big Island of Hawaii decrease beneath the deportment of the sea? 1. ~650,000 years 2. ~1.2 pet years 3. ~8 pet years 4. ~13 pet years 34) Discuss the Emperor Seamounts and note that it is a uniform fetter that reaches far north to the Aleutian Islands of Alaska. Using a expedite halfway betwixt that which you fitted in scrutinys 29 and 30, apportion the age of the oldest (furthest North) seamount in the Emperor Seamounts? (Hint 1- using the order code of the supporter implement procure not composition late the Pacific Extract had a powerful fluctuate in order, try using the track code of the supporter implement to communicate a balance accurebuke interval; Sketch 2- Late you comprehend the extract does not propose at the identical expedite balance interval, the age you estimated procure contend from the actual age inveterate on radiometric dating, for-this-reason your breach procure be contendent from the one absorbed in the lab manual!). 1. ~30 pet years 2. ~45 pet years 3. ~60 pet years 4. ~75 pet years Google Earth: Identifying Extract Boundaries 35.
