1. Evidence What is supports _
Warm Up:
Create a t-chart on page 7 of your notebook. List the evidence science has used so far to support our understanding of earth’s interior and how earth’s surface has changed. On the other side of the t-chart, identify what the evidence supports. I have provided you with an example.
Evidence What is supports _
1. seismic waves earth has layers, some are solid &
some are liquid

2. Essential Standard 8.E.2 Understand the history of Earth and its life forms based on evidence of change recorded in fossil records and landforms. 8.E.2.2 Explain the use of fossils, ice cores, composition of sedimentary rocks, faults, and igneous rock formations found in rock layers as evidence of the history of the Earth and its changing life forms

3. Obj: Relate evidence of change to Earth’s history, explain sea floor spreading by comparing a model of the process with the real process, identify changing landforms and the processes that create them using a plate map, and explain the relationship between earth’s interior and surface through a quick write.

4. Sea Floor Spreading Lab
Read the directions Complete the activity Answer questions completely

5. Map Reading Convergent Boundary: Divergent Boundary
continental – continental (c-c) Transform Boundary
continental – oceanic (c-o) Hot Spot
oceanic – oceanic (o-o)

6. On pg. 7 of your IN…. Using the plate boundary map
Create a color coded key for each type of plate boundary
Find and color a segment of each of the three types of convergent boundaries on the map, label with type (o-o, o-c, cc) and land form
Find and color a segment of a divergent boundary on your map, label land form created. (If you can find two divergent boundaries, one on land and one beneath the sea…even better!)
Find and color a segment of a transform boundary on your map
Find and color a hot spot

7. Map Reading Convergent Boundary: Divergent Boundary
continental – continental (c-c) Transform Boundary
continental – oceanic (c-o) Hot Spot
oceanic – oceanic (o-o)

8. Tectonic Map…..Where’s “Waldo” Identify the following features on your map using the letter. Put the letter on the location.
Hot Spot (find 2)
Divergent boundary at two ocean plates (find 2)
Divergent boundary at continental plates
Island Arc (find 2)
Coastal Volcanic Mountains
Folded Mountains
Subduction Zone & Trench
Transform boundary (find 2)

9. Can you see into the future?
Scale for your map: 1 cm = 1400 km
(divide 250 million year movement by 1400 to determine movement on map)
Pay attention to the arrows showing direction of plate movement!
Plate

10. 50 million years in the future

11. 250 million years in the future

12. Billions of years in the future, Earth’s core will have completely cooled. How will this affect earth’s surface?
