1. Tension is a force that pulls on the plates
(lithosphere)…. What does tension look like?
2. Compression is s force the pushes on the plates
(lithosphere). What does compression look like?
3. Shearing is a force that pushes on the plates causing
one to move in one direction and the other plate to
move in opposite direction. What does shearing look
like?
4. Where does do the forces come from to cause the
lithosphere to move?

CW: P.O.C.E.R. & heat transfer
HW: Read 1.2 in your text book
“Convection and the Mantle”
Take Cornell notes
 Use a small index card to put on top of the beaker of test
tube you are going to put on the top. Then once each
container is on top of each other then carefully pull out
the index card. Hold the containers carefully for several
minutes and observe what happens to the solutions.
 You should be asking yourself what does this have to
do with forces and the movement of the lithosphere?

 In which layer of the earth would you expect to find
the mixing of the two solutions (purple)? Why?
CW: Convection Current & heat transfer
HW: None
 What are the three types of heat transfer?
 How is heat transferred through space?
 What is a convection current?
 In general, what happens to the density of a fluid as it
becomes hotter?
 Describe how convection currents form.
 Name two layers of Earth in which convection currents
take place.
 What causes convection currents in the mantle?
 In your pod
Define radiation…..
 Next,
 Define Conduction…..
 Next,
 Define convection…..
 Heat transfer with no contact taking place between the
heat source and an object.
 Heat transfer within a material or an object when
direct touching is taking place.
 Heat transfer by the flow of an energized fluid. This
flow usually happens form one part of fluid to another
part.
 In your pod
Provide several examples of radiation….. …
 Next,
 Provide several examples of conduction …….
 Next,
 Define Provide several examples of convection….. ……
 What does density have to do with the flow of a fluid /
convection current?
 Hint:
 Once a flow of energized fluid begins does it lose its
energy?
 What will happen next….
 How would you describe atoms as they gain energy?
 Do these particle become less dense or more dense?
 How would you describe atoms as they lose energy?
 Do these particle become less dense or more dense?
1.
The core of Earth is really hot. How do you think
this affects what happens to the materials within the
mantle?
2.
How does the mantle and the materials within the
mantle affect what happens on the crust &
lithosphere?
