Fire and Ice: Identify and compare volcanic and glacial features on land and seafloor. part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Students learn about glacial and volcanic features by examining and comparing bathymetric and topographic images of the Sand Point area of Alaska. Students collect map evidence to determine which surface and seafloor features were formed by volcanoes and which were formed by glaciers. This data can then be used to hypothesize relative ages of the features. This lesson will familiarize students with the detailed bathymetric and satellite data that is collected and used by scientists to study the Earth. They will understand that the surface of the ocean floor is complex and varied. Scientists and students can use these types of data to study plate tectonics, ecosystems, natural hazards, climate change and Earth's history. Experience manipulating and examining data images will pique students' interest and inspire them to seek answers to their own questions.
