Earth’s future quick write 8

Homework:Homework:Study for informal quiz next class period…plate tectonicsStudy for informal quiz next class period…plate tectonics

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 1. earth has layers, some are solid & some are liquid

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

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.

Map Reading

Convergent Boundary: Divergent Boundary continental – continental (c-c) Transform Boundarycontinental – oceanic (c-o) Hot Spotoceanic – oceanic (o-o)

On pg. 7 of your IN….Using the plate boundary map 1. Create a color coded key for each type of plate boundary2. 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 3. 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!)

4. Find and color a segment of a transform boundary on your map5. Find and color a hot spot

Tectonic Map…..Where’s “Waldo”Identify the following features on your map using

the letter. Put the letter on the location.

A. Hot Spot (find 2)B. Divergent boundary at two ocean plates (find 2)C. Divergent boundary at continental platesD. Island Arc (find 2)E. Coastal Volcanic Mountains F. Folded Mountains G. Subduction Zone & Trench H. Transform boundary (find 2)

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 Speed (cm/yr) Movement in 250 million years

African .66 cm/yr 1650 km

Eurasian .95 cm/yr 2375 km

Indo-Australian 8.5 cm/yr 2125 km

North American 2.31 cm/yr 5775 km

South American 3.55 cm/yr 8875 km

50 million years in the future

250 million years in the future

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

Friday…..finally
