The big question addressed in lab, and a description of what you did.
In lab we discussed how we decide if something is a rock.
- coal, hardended lava, limestone, gravestone, iron ore, marble statue, and granite.
we also discussed the importance of how to asses our students as well as how to create activities that are relavent to their questions and prior knowledge
we also discussed the layers of the earth
- core (heat), mantle, crust (tectonic plates)
when tectonic plates collide they can create mountains, if land and water plate tectonic occur one goes on top of the other
igneous rocks- when magma cools
sedimentary - compaction and cementation (squished together)
metamorphic - heat and pressure
A description of what you learned in Thursday's lecture.
Earthquakes
Plate tectonics
Continental
Ticker, stick up above the water
Averages 20-30 miles thick
Oceanic
In the ocean basin
10 miles thick
If oceanic and continental plate hit, oceanic loses and goes under
Hawaii: Hot Spot
Rock cycle
Layers of the Earth
Inner core, outer core, mantle, crust
average mm/yr - sea floor spreading is measured using this scale
Answer questions about the weekly textbook reading:
What did you learn?
I learned about the three types of tecnonic plates. I understood the basis of what occurs with each plate however from the book and lecuture, I learned more in depth why it happens and where.
1. transform boundary
2. convergent boundary
3. divergent boundary
I also learned about volcanos and what the 'ring of fire' is. Earthquake acitivty occurs mostly on the coasts of continents.
What was most helpful?
It was helpful having the descriptions of the two different types of eruptions. I remember learning a little about it in natural disasters class but the brief overview was helpful.
What do you need more information on?
More information on the lithosphere and asthenspere would be helpful, the picture of tectonic plate boundaries.
What questions/concerns/comments do you have?
Do fossils have an effect on volcanos or earthquakes? How deep down in earths layers can fossils be found?
