PLATE BOUNDARIES 1
LESSON 5
AMAZING STARTER FOR YOU
IN YOUR NOTES, DESCRIBE THE 3 MAIN TYPES OF PLATE BOUNDARIES.
FOR YOUR NOTEBOOK:
Lesson 5: Vocabulary Basics of Tectonic Plates
Plates move of upwelling - convection currents that drive the plates to move
TECTONIC PLATE - A section of Earth's crust that floats on top of the MANTLE of the Earth.
CONVECTION- The flow of heated material
CURRENT - The way something moves
CONVECTION CURRENT - The way heated material moves!!!!!!
SUBDUCTION - When one plate moves underneath another.
Boundary Types
Convergent - When 2 plates move toward (converge) each other. This can result in subduction (one plate going under another) or plates folding like an accordion.
Divergent - When 2 plates move away (diverge) from one another. This can result in island formation and new crust.
Transform - When 2 plates brush by one another. This can cause some of our most violent earthquakes.
Factors in plate movement:
Plate Density (Higher density makes a plate sink under another plate when converging)
Plate Size
Continental (on land) or Oceanic (in the ocean)
TIME TO USE
TOOL # 1
YOUR GUIDANCE
Click on the tab that says Add Layer and select the category Earth Systems
Select Earthquakes, Plate Tectonics, Surface Elevation, and Volcanic Eruptions
Click on the tab that says Base Maps and make sure you select the Ocean map
On the left hand side of the screen, click on the icon with the small blue squares. This will allow you to manage the latitude and longitude lines. Click ON for both settings.
To alter the transparency of the different layers, slide the button on the bars. Play around with the settings so you can get used to using the map
TIME TO USE
TOOL # 2
YOUR GUIDANCE
Click on the tab that says “Plates”, this will show you where all of the plates lie.
Click on the tab that says “Plate Movements”, this will show you how each of the plates moves over time. Why do you think the arrows look different in certain areas? Why are some longer and some shorter?
Now turn on the subduction zones by clicking on the tab all the way to the right. What do you notice about where the subduction zones are located? Compare the subduction zones with where major earthquakes occur and describe the possible relationship.
Finally deselect all of the tabs above the map. Click on the tab, “Vent Fields” and “Plate Boundaries”. What is the relationship between the two? What will be created from the vent fields?
