Tracy Thomas

Tracy Thomas teaches Earth and physical geography at a public high school. She integrates satellite imagery and topographic data into classroom instruction, pairing coursework with an annual coastal field trip to study shoreline erosion and sedimentary formations. She also contributes to Biology Insights, reporting on geomorphology and continental landforms. Thomas maintains state secondary teaching credentials in geography, using physical models and field observations to show how tectonic shifts, weathering, and ocean currents shape the planet’s surface.
