🌍 Seismic Tomography: Waves, Travel Times, and Earth Structure

Help your students explore how scientists investigate the hidden interior of our planet with this engaging Grade 10 Science worksheet on Seismic Tomography. Designed to align with the Ontario Science curriculum, this resource introduces students to the fascinating relationship between P-waves, S-waves, travel times, and Earth's internal structure. Through carefully designed activities and visual learning opportunities, students develop a deeper understanding of how seismic data provides evidence about changes in temperature, composition, and material state deep beneath Earth's surface.

This classroom-ready resource encourages scientific thinking by connecting observable earthquake data with the unseen processes occurring inside Earth. Students analyze how seismic waves travel through different materials, compare wave behaviors, and interpret patterns that reveal important information about the crust, mantle, and deeper layers. Whether you're introducing seismic tomography for the first time or reinforcing a larger Earth science unit, this worksheet provides meaningful practice while supporting inquiry-based learning.
