When faults move

Today we simulated faults moving by apply force to move blocks that were attatched with velcro. Your data should have shown that more force was needed to move the block when friction was increased. No friction - then the block moved much easier.

Heating things up

By now you should be able to explain that the continents were once all together and that the ocean floor is spreading in some places. Now you can explain why this is all possible- CONVECTION! The same idea that causes wind and ocean currents can now explain what causes earthquakes and volcanoes. To understand this better we modeled convection currents using a special liquid and a candle.

We also made a study tool for tomorrow's notes on the layers of the Earth. If you did not finish you will have time to complete after your quiz.
