Earth Science Name ___________________________ Web Inquiry—Plate Tectonics/Earth’s Interior Date ____________________________ Standards: S6E5 Students will investigate the scientific view of how the earth’s surface is formed. a. Compare and contrast the Earth’s crust, mantle, and core, including temperature, density, and composition. d. Describe processes that change rocks and the surface of the earth. e. Recognize that lithospheric plates constantly move and cause major geological events on the earth’s surface. f. Explain the effects of physical processes (plate tectonics, erosion, deposition, volcanic eruption, gravity) on geological features including oceans (composition, currents, and tides). g. Describe how fossils show evidence of the changing surface and climate of the earth. I. Access this link http://www.geo.cornell.edu/hawaii/220/PRI/PRI_PT_home.html Explore the areas of this site. Look at the maps where earthquakes have occurred and where land features along plate boundaries are located. Be sure to watch the convection video at Plate Motion. Name some volcanoes formed at hot spots. II. Access this link http://www.divediscover.whoi.edu/anatomy/index.html 1. Explore Earth’s Anatomy. Record any new facts/information you discover about each layer ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ 2. From the pull down tab at the top, access “Dive into Deeper Discovery” and begin the interactive for Mid-Ocean Ridges. Be sure to view Magnetics and the Axial. Look for Alvin. What are some features near the mid-ocean ridge? ____________________________________________________________________________________ What are some lifeforms surviving in this area? ____________________________________________________________________________________ 3. Explore the Plate Tectonics Theory interactive. Watch the breakup of Pangaea. Identify the plate boundary types by the plate movement. ____________________________________________________________________________________ What other mountains have been created by plates? ____________________________________________________________________________________ III. On your own, explore this PBS site: http://www.pbs.org/wnet/savageearth/index.html There are a number of animations to view, including earthquakes, volcanoes, faults, and subduction.
