Weathering, Erosion, Deposition "Quiz" KEY

# data[].attributes.body
Slide 1: Chemical weathering forms caves; acidic water dissolves away limestone rock

Slide 2: Unsorted sediments; they range in size from small to large

Slide 3: Erosion; water is moving sediments downstream

Slide 4: Water; abrasion (particles grinding together) wears away sharp corners and rounds edges

Slide 5: Stream; this feature is an alluvial fan (delta deposit formed on land)

Slide 6: Chemical weathering; acid rain is dissolving pits in the limestone rock

"Geologic Creation of the Grand Canyon" video

Watch the video below about the formation of the Grand Canyon at least 2 times, then write a 3-4 sentence reflection about what you saw. Be sure to discuss how water erosion shaped the Grand Canyon (2 ways)

xRez Studio has completed an animated sequence illustrating the geological forces leading to the creation and carving of the Grand Canyon for use in the new visitor center film "Grand Canyon: A Journey of Wonder", produced by Aperture Films. Working under direction of noted geologic consultants Karl Karlstrom and Carl Bowman, the animation follows the initial formation of the Vishnu Mountains 1,750 millions years ago (MYA), to sedimentation from ancient seas at 500 MYA, to the uplift of the Colorado Plateau at 70 MYA, and ultimately the act of final carving of the canyon at 6 MYA. Other key geologic concepts such as the Supergroup were omitted for brevity in order to allow easy comprehension in a short span within the film. Narration will further augment understanding in the final edit and screenings.
