2: Look for Patterns
Students will compare the map they created in Lesson
1 to a
map showing tectonic plates and look for a relationship.
Draw conclusions and find patterns in collected data
Deduce a cause/ effect relationship from given data.
Determine how plate movements relate to earthquake activity
One or two 45 minute class periods.

Direct students to Activity 2 in the Student Activities section.
After students have gone through the lesson on their own, have a group
discussion centering on the major concepts of the lesson.
Most earthquakes and volcanic eruptions do not strike randomly but occur
in specific areas, such as along plate boundaries.
Moving plates interact along their margins, which is why the majority of
the Earth's earthquakes are found at or near plate boundaries.
Plate tectonic forces are most evident at convergent boundaries where plates
are moving toward each other.
One of the most active plate boundaries where earthquakes are frequent
is around the massive Pacific Plate commonly referred to as the Pacific
Ring of Fire.
Most earthquakes occur at depths of less than 80 km (50 miles) from the
- The answers in the students' project journals / notebooks OR worksheets can be used for assessment
(e.g. Are the answers complete, accurate, and do they show an understanding of the lesson concepts?).
