This passage explores the causes of earthquakes at tectonic plate boundaries. The dynamic Earth is constantly shifting due to plate movement, which is why earthquakes occur. There are three main types of boundaries: divergent, where plates move apart; convergent, where plates collide; and transform, where plates slide past each other. Each type of boundary can trigger earthquakes, with convergent and transform boundaries being the most common culprits.

Reading this passage strengthens vocabulary skills by introducing terms like “convergent” and “divergent” boundaries. It enhances reading comprehension by breaking down the causes of natural disasters in a clear, structured way. Critical thinking is encouraged as students are prompted to consider how different types of plate interactions result in earthquakes. This passage also refines grammar understanding, particularly in the use of cause-and-effect sentence structures.
