New Lesson with Globe Overlay: Intro to Earth's Seismicity
Earth Seismicity self-adhesive globe overlay
- Uses IRIS earthquake data (IRIS data)
- Overlay available for 18" and 10" globes
Intro to Earth's Seismicity lesson plan
Promote an understanding of Earth's seismicity through observations, interpretations, and open discussions
The students will:
- Use real geographical, geophysical, and geological data to make scientifically meaningful observations
- Analyze globes, maps, and graphs, and create cross-sections to visualize data in 3D that is traditionally presented in 2D
- Plot earthquake foci using analysis of spatial and statistical data
- Apply observations and insights to develop interpretations and hypotheses
- Synthesize data and information
Context for use:
- 18" or 10" Real World Globe
- RWG Earth Seismicity self-adhesive overlay
- Dry Erase marker
- Earth Interior work board
- Colored pencils (purple, blue, green, yellow)
Appropriate for high school and undergraduate-level introductory geology, natural hazards, and other geoscience courses where the students have already had a basic introduction to plate tectonics.
They should already know that Earth is broken into plates that are constantly in motion and that the boundaries of these plates are broadly characterized into three types: convergent, divergent, and strike-slip.
This lesson is intended to be worked by groups of 2 - 4 students followed by an all-inclusive class discussion.
Lesson can be easily adapted
to serve both small- and large-enrollment classes, and be used in both lecture and lab settings.
Lesson can be easily combined with other lessons
