This document is a grade 10 science diagnostic test focused on geological concepts such as plate tectonics, earthquakes, and volcanic activity. It includes multiple-choice questions designed to assess students' understanding of various theories and processes related to Earth's crust and its movements. The test covers a range of topics including the nature of tectonic plates, volcanic locations, and the implications of seismic activity.
