Effects of Plate Tectonics
2
Warm-Up

• Write a caption for the cartoon
• Answer the Think about It questions on page 97.

3
Goals

• Use the maps to examine the distribution of
  earthquakes and volcanoes to the location of
  plate boundaries
• Explain the location, nature, and cause of
  volcanic arcs in terms of plate tectonics
• Explain the location, nature, and cause of hot
  spots
• Explain how plate-tectonics processes have caused
  continents to grow through geologic time

4
Goals continued

• Explain how plate-tectonic processes produce
  landforms.
• Explain how plate tectonics can affect the
  interior of a continent.

5
Investigate

• First write the names of two plates that are
  moving toward each other.
• Name two plates that are moving apart.
• Name two plates that are sliding past each other.
• On the map color the boundary line that separates
  two converging, diverging, or transforming plate
  boundaries. Make a color key that shows this
  color code.

Investigate

• Page 98 , Answer 1, 3-8.
• Digging Deeper page 102
• Each group will summarize one paragraph
• Then go back to your groups and share with them
  what you learned in the paragraph you summarized
• Answer Check Your Understanding page 105, 1-4

Match the geologic features to the type of plate
boundary (A-E) with which they are typically
associated

• Geologic Feature
• Transform fault
• Mid-ocean Ridge
• Island arc boundary
• Volcanic arc
• Continental Mountains

• Plate Boundary
• Divergent Plate boundary
• Oceanic- oceanic convergent plate boundary
• Ocean-continental convergent plate boundary
• Continental-continental plate boundary
• Transform plate boundary

  glossary
• Answer Understanding and Applying What You Have
  Learned page 106 1-4
• Write at least one paragraph to Preparing for
  the Chapter Challenge page 106

Warm-Up

• Why are most high mountain ranges located at or
  near plate boundaries?
• Do all volcanoes occur at plate boundaries?
  Explain.
