  2. Landslides Negative environmental effects include: • Blocked roads • Damaged and destroyed homes • Destroyed habitat • Damaged power lines

  3. landslides

  4. Wildfires • A natural event in most forest ecosystems • Can be beneficial to the ecosystem • Necessary in the life cycle of some trees • Generally, neither good or bad • Typically caused by humans or lightning

  7. Floods • An unusually high water stage • When water overflows its natural or artificial bank onto normally dry land • Two types of floods: river flood and flash flood (quick and dangerous)

  8. Floods Factors that contribute to flooding include: • Heavy, intense rainfall • Over-saturated soil (soaked with water) • High river, stream, or reservoir levels • Urbanization (buildings, parking lots)

  9. Floods Negative environmental effects include: • Endangering human and animal life • Damaged property • Soil erosion • Sediment deposition
