Students will answer questions about the online Science News article “How the Earth-shaking theory of plate tectonics was born,” which explores how scientists formed the theory of plate tectonics. A version of the story, “Shaking up Earth,” can be found in the January 16, 2021 issue of Science News.
Rocks found across the world offer clues to geological processes, as well as the history of Earth and the rest of the solar system. In this activity, students will review types of rocks and the rock cycle and will apply that knowledge to interpret data on two rock samples.
These discussion prompts explore volcanic explosivity and collapse, the ecosystem and health effects of eruptions and how to keep people safe during natural disasters.
