Earth's Layers Investigation
🌍 Part 1: Earth's Surface Materials
1. What makes up most of Earth's surface layer?
Only solid rock
Sediment and solid rock
Only water and air
Only loose soil
2. Bedrock is:
Always found on top of sediment
Solid rock that can be on or below Earth's surface
Only loose pieces of rock
The same as sediment
3. Check all materials that are considered sediment:
Sand
Gravel
Solid granite bedrock
Loose soil particles
4. In your model from class, the sediment layer was positioned _____________ the bedrock layer.
Answer: _________________
🔥 Part 2: Heat, Pressure, and Rock Changes
5. As you go deeper underground, what happens to temperature and pressure?
Both temperature and pressure decrease
Both temperature and pressure increase
Temperature increases, pressure decreases
Temperature decreases, pressure increases
6. Based on our data analysis, which type of rock is denser?
Ocean crust rock
Continental crust rock
They have the same density
It depends on the temperature
7. Explain how heat and pressure change rocks as they get deeper underground. Use evidence from our class activities.
8. Compare ocean crust and continental crust using data from our investigation:
Ocean crust: _________________________________
Continental crust: _____________________________
🏗️ Part 3: Modeling Earth's Materials
9. Draw and label your updated Earth's layers model. Include sediment, bedrock, and show how rock changes with depth.
10. How might the properties of bedrock affect what happens during earthquakes? Explain your thinking.
11. Complete this "I can" statement based on what you learned:
I can explain how Earth's materials cycle because _______________
