Week 10

 What did you do in lab today?

- We reviewed our Activitymania homework in small group and whole group

- talked about assessments and the letter grade increases

- we worked on the curving for our exams

What are the layers of the earth?

- core (inner and outer)

- mantle

- Crust 

How do plates moves?

- The movement of the plates is driven by convection currents in the mantle. Heat rises from the mantle and cools as it gets closer to the surface; from there, it sinks down where it is reheated and the cycle repeats. This creates a current that moves the plates. Although they are constantly moving, each plate moves very slowly–about 3 to 5 centimeters (1 to 2 inches) per year.

What are the three types of tectonic plate boundaries?

  1. Transform boundary: plates sideswipe each other 
  2. Divergent boundary: plates pull apart from each other
  3. Convergent boundary: plates push into each other
Rock Cycle: (examples with starbursts) 
- sedimentary: cemented and compacted together

- igneous: melted and then cooled










- metamorphic: heat (not enough to melt) and pressure









Arrows are the rocks cycling to other rocks
EW = erosion and weathering 
H = heat 
P = pressure 
















3.What did you learn in Thursday’s discussion?


Layers of the earth (in order from inner to outer)

  • Inner core

  • Outer core

  • Mantle 

  • Crust (converge, diverge (coming together), and slide) 


Extrusive igneous rocks are smaller crystals because they have cooled faster outside of the earth. 


Intrusive igneous rocks are bigger crystals because they have time to grow on the inside.


Metamorphic rock: heat and pressure melded two rocks together.


Sedimentary rock: little rocks/sand that has been compacted into one. 


4.Read the online textbook, chapter 5: https://pressbooks.uiowa.edu/methodsii/chapter/earth/

1.What did you learn?

Convergent plates: When two continental plates converge, the land is pushed into each other and upward forming a mountain (however, it also pushes down into the mantle due to it being made of a liquid substance).


Divergent plates:  In the ocean, magma rises up to fill the space between plates and a volcano is formed. When the material from the volcanic eruptions builds up over time, it forms a .
