How volcanoes and Earthquakes are formed- Part 1- an introduction to the moving earth
PART 1:
1. Review from your 7th grade lessons the layers of the earth, from the following website.
http://volcano.oregonstate.edu/vwdocs/vwlessons/lessons/Earths_layers/Earths_layers2.html
Label the picture below showing which layer is which. Then answer the following questions.
QUESTIONS
1. Which layer is the densest?
2. Which layer has the ability to flow?
PART 2:
2. Here you will answer the question: What does earth’s crust look like?
Study the maps from the following website and copy them onto your map below

o=investigation
Use red to dot all the earthquakes
Use blue to dot all the volcanoes
Use green to dot all the mountain belts
Then answer the following questions.
QUESTIONS:
1. Is there a relationship between where mountains, volcanoes, and earthquakes appear? If so what is it?
2. What can you imply about how earth’s crust is shaped below us? Is it one giant layer solid mass that floats
above the mantle, or is it broken pieces that all float together above the mantle? Why do you think so?
PART 3:
Read the following webpage and answer the following questions
http://www.cotf.edu/ete/modules/msese/earthsysflr/plates1.html
QUESTIONS:
1. What does the theory of plate tectonics suggest about earth’s crust?
2. How many plates do scientists think there are? Name 4 of them.
PART 4:
Look at Each video and several of the pictures/ modules below to get a correct idea and definition of each kind of
fault, or tectonic plate movement listed below.
1. Draw a picture of what each kind of fault looks like after the plate movement.
2. In the before picture draw a fault line and arrows to show the direction of movement
3. and explain what is going on in the caption

Questions:
1. There are 3 kinds of boundaries between plates. Each of these boundaries are represented in the pictures above.
Match the following process with the boundary type it is also an example of:
A. SUBDUCTION ZONE
1. Divergent Boundary
B. TRANSVERSE STRIKE SLIP FAULT
2. Convergent Boundary
C. MID-OCEAN RIDGE
3. Transform Boundary
Use the following website to read and explain the 3 different boundaries

2. Look at the following rock formation and see how Geologists can find information about the past. Answer the
following questions.
