Plate tectonics is an important topic for both geography and geology. The interaction between tectonic plates produces the basic configuration of Earth's continents and ocean basins. This interaction also produces the major topographic features such as long mountain chains, deep sea-floor trenches, and even chains of islands. In the lecture and readings about plate tectonics, you learned about different processes of plate tectonic collision, extension generating sea-floor spreading, the side-by-side transform motion, and also hot spots from plumes in the mantle. The matching questions ask you to apply your knowledge of plate tectonics to real- world examples as viewed by Google Maps' bathymetry (ocean-floor topography) and aerial views, as well as some Google Street view imagery. 0.5 / 0.5 pts Question 1 You will match different locations on Earth imaged by Google Maps or Google Street Views to plate tectonic locations and processes of significance on Earth. Some of these locations will represent the boundary between two plates. Other locations will have other significance to plate tectonics as discussed in this lecture (http://www.asu.edu/courses/gph111/BreezeLectures/16PlateTectonics/16PublishPlateTectonics/index.htm) and readings (http://earthonlinemedia.com/ebooks/tpe_3e/tectonics_landforms/tectonics_introduction.html) .

The Red Sea is where spreading is taking place between the African plate and the Arabian plate. Northern Turkey has the North Anatolian fault zone, which is very much like the San Andreas transform plate boundary -- in this case between the Eurasian plate and the Anatolian Plate. The Caribbean trench is a location of plate tectonic collision between the North American plate and the Caribbean plate. Yellowstone is a hotspot in the middle of the North American plate. 0.5 / 0.5 pts Question 2 Chains of volcanoes -- all lined up in a row or an arc -- are often produced by plate tectonic processes: collision between two ocean plates; collision between an ocean and a continental plate; a tectonic plate moving over a hotspot; and

The Cascade volcanoes like Mt St. Helens, Mt. Hood, Mt. Baker and others are produced through the collision of an ocean and a continental plate. The Marianas Islands are an ocean arc that is a result of collision of an ocean and an ocean plate. The very long chain of islands that runs from Hawaii to Midway is a result of the Pacific Plate moving over a hot spot. 0.25 / 0.5 pts Question 3 You will match different locations on Earth imaged by Google Maps or Google Street Views to plate tectonic locations of significance on Earth.

Correct! This view of the bathymetry and topography of this plate tectonic zone (https://www.google.com/maps/pl Boundary between the Naz Correct! Correct! Boundaries between major tectonic plates often leave very significant impacts on Earth's surface. In this case, the San Andreas Fault in California leaves a scar across the landscape. The Levant Fault zone that runs through the Dead Sea is a zone of left-lateral motion and also subsidence between the Arabian and African plates. Collision of the Indian plate into the Eurasian plate produced the Himalaya Mountains, and collision between the Nazca plate and the South American plate produced the trench seen in the bathymetry and also the Andes Mountains.
