• Following Instructions Lessons
• Drawing Lessons
• Finish Converging And Transform
Fault Boundaries
What we will learn…
• Convergent plate boundaries are called destructive plate
margins because lithosphere is being destroyed (actually
recycled) at these boundaries.
• There are three types of convergent boundaries: oceaniccontinental, oceanic-oceanic, continental-continental.
• A subduction zone occurs when one oceanic plate is
forced down into the mantle beneath a second plate.
• At a transform fault boundary, plates grind past each
other without destroying the lithosphere.
How we will do it…
• Whole class
instruction
• Exemplars
• Reading
• Answering
questions
• Drawing
Think-Pair-Share
1. What are the reasons why teachers have
you read, draw and answer questions?
2. What are the reasons science teachers
have you keep a notebook?
3. What are your goals in this class?
4. How well is your work helping you meet
your goals?
Assignment: Converging and Transform
Fault Boundaries p. 261-264
1. If new lithosphere is being created at divergent
boundaries, is Earth’s crust getting bigger? Explain your
answer.
2. Why are convergent plate boundaries called destructive
plate margins?
3. What is a subduction zone? Where do subduction zones
occur? Why do trenches occur at subduction zones?
4. List the three types of convergent boundaries.
5. Draw the picture of the oceanic-continental convergent
boundary on p. 261. Remember to label parts. Use your
own words to describe what is happening at an oceaniccontinental boundary. Identify an example of where this
feature can be found on Earth.
Assignment Questions Continued
6. Draw the picture of the oceanic-oceanic convergent
boundary at the top of p. 262. Remember to label parts.
Use your own words to describe what is happening at an
oceanic-oceanic boundary. Identify an example of where
this feature can be found on Earth.
7. Draw the picture of the continental-continental convergent
boundary at the bottom of p. 262. Remember to label
parts. Use your own words to describe what is happening
at an continental-continental boundary. Identify an
example of where this feature can be found on Earth.
8. What happens at transform fault boundaries? Where are
most transform faults found? Where is an example of a
transform fault boundary that cuts through continental
crust?
