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 Earth's surface.
- 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?).
The following instructions for Student Activity 2 are printed in the Student Activities section of this web site.
