Original Prompt

create a worksheet that ties convection currents in the mantle to plate movements in the Earth's crust

This worksheet focuses on the concept of mantle convection, a process whereby heat from Earth's core creates convection currents in the semi-solid mantle layer beneath the crust. Students will learn how these currents are responsible for the movement of tectonic plates, contributing to geological features such as mountains and volcanoes. The document includes guided exploration activities, diagram analyses, and case studies, particularly focusing on phenomena like the Mid-Atlantic Ridge and its associated divergent boundary. Through these exercises, students will develop a comprehensive understanding of how heat transfer contributes to tectonic plate dynamics.
