o Read about the Colorado flash food of 1976o Define “risk” and relate it to natural catastrophic events.o Examine sample hurricane data as a way of describing the probability that an

event will occur.o Review the Anchor Activity WebQuest for guidelines for the research and

grading rubric.o Select a topic of study for the project.

that occurred during the 1990s.o Analyze the locations of earthquakes around the world.o Locate three areas of intense earthquake activity on a map.o Hypothesize about the reasons for patterns in the locations of

earthquakes.• Activities

o Inquiry 13.1 Plotting Earthquakes To Identify Patterns

• Links o Ring of Fire Worksheeto Ring of Fire o Theory of Plate Tectonicso Mid-Ocean Ridgeo Seafloor Spreading

• Readings o Magnitude & Intensity

• Vocabularyo Oceanic Crusto Continental Crusto Mantleo Outer Coreo Inner Coreo Lithosphereo Asthenosphere

• Objectiveso Examine the interior structure of some common objects.o Discuss how scientists study the structure of the earth’s interior.o Recognize that an understanding of the motion of earthquake waves cn help

scientists formulate hypotheses about the earth’s interior.o Using computer images, identify and describe the layers of the earth.o Plot the locations of volcanoes and compare these locations with those of

earthquakes.

• Objectives o Describe what a model is and distinguish models from real objects or events.o Use models to simulate the movement of lithospheric plates as they collide, separate, and slide past one

another.o Use a globe and a map to find evidence of plate movement and to identify landforms—such as mid-ocean

ridges, mountains, and trenches—that result from plate movement.o Classify materials as either brittle or ductile.o Investigate the effects of applying a force to a model of a fault.

• Objectiveso Use a flow indicator, rheoscopic fluid, to model

convection currents in the mantle.o View computer images of the earth’s interior to

observe convection in the mantle.o Use appropriate vocabulary when communicating

ideas about the earth’s interior layers.o Identify movement in the earth’s mantle as one

cause of plate movement, earthquakes, and volcanoes.
