cocos plate and north american plate boundary type
Transcribed image text: Question 1 (1 point) Saved Unclick all the other layers you've been using, and then click next to "plate boundary model" layer. The low region between the two mountain ranges is the Puget Sound area of Washington and the Willamette Valley in Oregon. The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia. nazca plate and south american plate boundary type Another, Wrangell-St. Elias National Park, is a vast region that extends across the accretionary wedge and volcanic arc, and is built of accreted terranes. When the plates suddenly let go, a massive earthquake will shake the entire Pacific Northwest, a series of tsunami waves will pound the Coast, and landslides will make it difficult to reach some of those in need. The Coast Ranges, including the Olympic Mountains, are made of oceanic sediments and hard rocks that were caught in the vise between the converging plates, uplifted, and added to the edge of the continent. The spectacular pillow lavas seen on the road up Hurricane Ridge indicate that lava formed on the sea floor and was later uplifted. Antarctic plate, Pacfic plate, Eurasia plate, India Plate, Africa plate. Modified from "Beauty and the Beast: Plate Tectonics and the Landscapes of the Pacific Northwest", by Robert J. Lillie, Wells Creek Publishers, 92 pp., www.amazon.com/dp.1512211893. A map of the ocean floor reveals a deep underwater trench (dark blue line) running along the southern coast of Mexico, defining the boundary between two tectonic plates. The major plates are Eurasia, Pacific, India, Australia, North America, South America, Africa, and Antarctic. (Click on arrows and slide left and right to see labels.). 20 Million Years Ago In the past, that was true. This plate includes Australia and much of the surrounding ocean. Australia plate, Eurasia plate, Africa plate, Arabia plate. At an ocean-continent convergent boundary, the oceanic plate is pushed under the continental plate in the same manner as at an ocean-ocean boundary.

Lillie, Wells Creek Publishers, 92 pp., 2015, www.amazon.com/dp/1512211893. Lake Clark National Park and Preserve contains an active composite volcano with a profile and recent history reminiscent of Mt. As the Juan de Fuca Plate (lower cookie) subducts beneath the North American Plate (upper cookie), the layers are scraped off the ocean floor and pile up as the Coast Range. Forty million years ago, a large tectonic plate, known as the Farallon Plate, was between the Pacific and North American plates. By 50 Ma, Australia had separated from Antarctic, and shortly after that, India collided with Asia. 40 Million Years Ago
