slide1. A history of earth The Geological time scales<br>
slide2. How old is the Earth? 4.6 Billion years
4,600,000,000
Divided into eras:
Cenozoic
Mesozoic
Palaeozoic
Precambrian<br>
slide4. How long was the Paleozoic Era?<br>
slide5. How long was the Paleozoic Era?
299 million years<br>
slide6. Major events in the Paleozoic Era<br>
slide7. Events in the Devonian and Silurian periods<br>
slide8. • Today, you will create a scale timeline of Earth’s history on a long sheet of adding machine paper
• Scale: 1 inch = 100,000,000 years
• 4.6 billion years = 46 inches Scale Timeline: Paper Timeline<br>
slide9. You may use:
• Meter sticks (even though we’re using inches)
• Decimal inch rulers
• Your textbooks
• Copies from other textbooks
• The internet Scale Timeline: Paper Timeline<br>
slide10. Earth’s timeline worksheet Table 1<br>
slide11. Table 2<br>
