B- Earth and Space Science 11 - Today we start by looking at the difference between explosive and effusive volcanoes. There are four main factors at play here:
- The viscosity of the magma
- The amount of dissolved gasses in the magma
- The speed at which pressure is released when magma nears the surface
- The amount of heated ground water
Lastly we'll watch Pompeii: The Last Day and see some very cool recreations of the eruption at Mount Vesuvius that destroyed Herculaneum and Pompeii.
A - Law 12 - Today we will finish the drinking and driving activity we started yesterday. This activity is due Monday.
D - Geography 12 - Today we're looking at streams and drainage basins. You'll need to work on a few definitions, a diagram, and questions 1, 3, 10, 11, and 12 from page 481 in your Geosystems textbook. A map of Canada's drainage basins can be found here. and the Canadian Atlas online has a great section on drainage basins too. Notes on these topics can be found here.
