Question 2

Check for understanding - match each description or example with the correct plate boundary.

  • Where an oceanic plates slides beneath a continental plate
  • When two plates are sliding apart
  • When two plates are colliding / crashing
  • Example: Himalayan Mountains, Cascade Mountains
  • Example: Hawaiian Islands
  • Example: San Andreas Fault
  • When two plates are sliding against each other in opposite directions
  • Where a suubduction zone occurs
  • Where new ocean floor is created
  • A magma plume rising to the surface in the middle of a plate
  • Convergent boundary
  • Divergent boundary
  • Transform boundary
  • Hot spot

Model Version #2.
A few weeks ago, you drew your initial idea of why Mt. St. Helens erupted. Since then, we drew a model as a class, and learned about the layers of the earth and plate tectonics. Below, draw an updated model with at least 2 new details. Include the earth layers, tectonic plates, labels, and arrows to show what forces are at work. Describe your drawing in the box.
