📚 Quick Study Guide

  • 🌋 Earthquakes: Earthquakes are sudden, rapid shaking of the Earth caused by the movement of tectonic plates.
  • 🏞️ Surface Changes: Earthquakes can cause significant changes to the Earth's surface, including cracks, landslides, and changes in elevation.
  • 🚧 Cracks: Cracks in the ground are a common result of earthquakes, forming where the ground is pulled apart or compressed.
  • ⛰️ Landslides: Earthquakes can trigger landslides, where large amounts of soil and rock move downhill.
  • 📏 Measuring Earthquakes: The magnitude of an earthquake is measured using the Richter scale.
  • 🧭 Tectonic Plates: Earth's crust is divided into several large plates that are constantly moving. Earthquakes often occur along the boundaries of these plates.
  • 🌱 Vegetation Impact: Surface changes caused by earthquakes can impact vegetation and ecosystems in the affected areas.
