Objective: Deduce the type of plate boundary given images or descriptions of surface features. Make a drawing for each showing key processes and labeling with key vocabulary.

With the following link, use the plate tectonics simulation to figure out the plate boundary type for each surface feature below.

http://phet.colorado.edu/en/simulation/plate-tectonics

You will need to download the plate tectonics simulator. Once downloaded, click on the “plate motion” tab. Take some time to get to know how to use the simulator.

Hints:1. Turn labels “on”2. Turn on “show seawater”

For each surface feature below you are given an image(s). a. Try running different simulations and seeing what type of surface formation appears. b. Draw a picture showing the boundary type and any associated processes and features. c. Use the word bank below to help label each picture with all associated terms.d. Label the relative density (less dense, more dense) of each type of crust

Word Bank:• Island Arc• Mid-ocean ridge• Sea-floor spreading• Rift Valley• Subduction• Mountain building• Coastal volcanoes• Shifting of Earth’s surface

• Transform Boundary• Divergent Boundary• Convergent Boundary• Oceanic Crust, old• Oceanic Crust, New• Continental Crust• Lithosphere• Mantle

1. Island arc: Magma from Earth’s crust creates volcanoes that form arcs of islands in the ocean.

2.

Mid-ocean ridge: a string of underwater mountains, with a deep valley running along its crest. Rocks of the ocean floor are very young near it.

3. Mountain building: Earth’s crust buckles, folds, and thickens, pushing up mountains.

4. Coastal volcanoes: Magma from Earth’s mantle rises to surface and layer upon layer forms volcanoes along a coast.

5. Rift Valley: Earth’s crust splits and fills with magma over and over, forming a valley and eventually filling with water.

6. Shift

in Earth’s surface: Earth’s surface slides past and moves surface features horizontally.
