Presentation transcript:

Thank you for not chewing gum or anything else  Materials: Pencil Notebook Packet Lab Text D-42 Tuesday, January 17 Agenda: Bell work Activity 45 - Understanding Plate Boundaries Daily Objective: Today we will learn how plate movement is related to landforms and earthquakes. Daily Question: How does the theory of plate tectonics, explain the locations of earthquakes, volcanoes and mountains?

Activity 45: Understanding Plate Boundaries Procedure: -Read the activity - As you read complete the notes worksheet-Student Sheet 45.1 When you are done: work on your study guide

Transform Earthquakes Ex: San Andreas Fault

Divergent Volcanoes Ridges Ex: Mid-Atlantic Ridge

Video Video - Magma

Convergent Plate Boundary Oceanic/continental asthenosphere - is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement Subduction - process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge Ex: Andes Mountains Cascade mountain Range Subduction

Continental/Continental Convergent Plate Boundary Earthquakes Mountains Ex: Himalayan Mts.

Oceanic/Oceanic Convergent plate boundary. Trenches Volcanic Island mountains Earthquakes Ex: Solomon Islands

Hot Spots Hot Spot: volcanic regions thought to be fed by underlying mantle in which magma is trapped and hot compared with the mantle in other places. Ex: Hawaii & Yellowstone
