X (you are here)

4. Where are We? Earth is one of 8 planets Earth Revolves around the Sun
Moon revolves around Earth
Sun + Planets = Solar System

5. Where did Earth Come From?...

6. The Nebular Hypothesis
Everything in our Solar System came from
a HUGE, spinning, cloud of dust & gas.
Hypothesis?...
Nebula?...
“Nebula” = Cloud of dust & gas in Space

7. Nebular Hypothesis: Nebula spun really fast Flattened
Dust squishes together in middle
Forms SUN
Other Solids squish together and form planets

8. 1. Nebula
2. Spins…
3. Sun!
4. Planets!

9. Earth’s Layers Layers! Lighter Material = Outside Planets
Heavier Material = Inner Planets
After Earth formed, interior melted
heavier elements sink to middle ↓
lighter elements float to surface ↑
Layers!

10. Mariana Trench Earth’s Deepest Trench VERY COLD, HIGH PRESSURE
Lowest point – vent species (molten hot)
Where is heat coming from?

11. Quick Quiz #1 What are the five steps of the Nebular Hypothesis?
Where are the heavier rocks found on Earth? How does this differ from the lighter rocks?
Why do you think the rocks arrange themselves in the way described in #2?
