Weekly Blog- 10/12

Summary:
The week started of with learning more about shield volcanoes, especially how they are formed; the layers of magma cool on the surface forming a shield over the volcano. While Hawaii volcanoes are shield volcanoes in Japan are composite. That means that composite volcanoes are explosive, but shield volcanoes lava flows down slowly. Making a composite volcano erupt replicated a volcano in Japan. Looking at a map showing plate boundaries, earthquakes, and volcanoes allowed me to see how all of three are in vaguely in the same place. The volcanoes occurred on the plate boundaries because when the plates shifted the may have created a crack that allowed magma to flow upward. The earthquakes occurred because when the plates shift the cause different movements created an earthquake.I showed how different geologic forms are created by movement in the crust when I made my food model. It showed the oceanic crust, continental crust and the asthenosphere layer. It showed my how mountains and earthquakes were formed in a different point of view!
SP2: Developing and using models:
I used models to explain and predict behaviors of systems, or test a design as I erupted my volcano with baking soda and vinegar. The eruption of the volcano showed me how a composite or strato volcano would erupt. The model helped me visualize the difference between shield volcanoes and composite volcanoes.
