Our work today was a quick review of the relationship among the average speed at which something travels, the amount of time it travels at that average speed, and the distance it travels during that time. Because we used different units for distance and time, we also had to convert units.
Assignment:
We considered position graphs and velocity graphs today. You should be able to describe how something would have to move to make any of the following graphs, all of which are for different motions: Assignment:
Students moved to generate position vs time plots, which we could then begin to interpret. For example, can you describe how an object had to move to make a position graph like this one?
We finished up our discussion of caldera eruptions and the material that falls from the sky in an explosive eruption, namely ash, cinders, and bombs!
Assignment:
Cinders and ash and bombs, oh my!
In 1992 Mount Pinatubo in the Philippines had the largest volcanic eruption in recent memory. It ended the US presence at nearby Clark Air Force base. You should know which tectonic plates are the source of this volcano. Something of the awesome power of this eruption was apparent in the video we saw, including the apparent fear it fostered in the geologists monitoring it.
Assignments:
Mafic and felsic magma are different from each other in one important way, so far as volcanoes are concerned. You should be able to explain to your parents how they differ and to give examples of volcanoes that illustrate this basic difference.
Assignment:
Volcanoes come is three basic varieties, shield volcanoes, cinder cone volcanoes, and composite volcanoes.
Assignment:
Tsunamis and buildings in earthquake zones were on the docket today. We're all but finished with Chapter 6.
LaPalma volcano may have an impact on the U.S. east coast. Why do geologists think that this is a potential threat? Assignments:
