The document discusses both slow and fast changes that occur on Earth. Slow changes involve mechanical and chemical weathering over long periods of time, such as erosion from wind and water or rocks breaking down from chemical reactions. Fast changes include sudden natural disasters like landslides, earthquakes, tsunamis, and volcanic eruptions. Volcanoes are further explained as coming in different types like shield, cinder, and composite volcanoes. The final section instructs the reader to choose a type of volcano to research and create a PowerPoint presentation about, including labeling parts of a volcano diagram and finding an image of a real volcano.

1. EARTH CHANGES
S..L..O..W…..
And Fast!

2. S..L..O..W… changes
• MECHANICAL WEATHERING

3. S..L..O..W… changes
• EROSION- Pick Up, Move, Deposit
– Wind, Water

4. Is Erosion a Big Deal?

5. S..L..O..W... changes
• CHEMICAL WEATHERING
• Rocks break down through Chemical Changes
causing big changes
• Can be done by:
– Water
– Oxygen
– Carbon Dioxide
– Acid Rain
Chemical Weathering CHANGES rocks permanently!

7. FAST Changes
• Landslides
• Earthquakes
• Tsunamis
• Volcanoes

8. VOLCANOS
• Different Types
– Shield
– Cinder
– Composite
– Spatter
– Complex
