Natural Disasters and Earth Changes

The video reviews natural disasters and their impact on Earth's surface, including earthquakes, volcanoes, underwater volcanoes, landslides, and floods. It explains how these phenomena occur and their effects on the environment. The role of geophysicists in studying these changes is also discussed. The video concludes with a review of key vocabulary and an exit ticket activity.
