EARTH SCIENCE
1. Recall from reading the nature of volcanoes, and in your own words, briefly discuss how the rate of cooling determines the type of rock that forms from magma/lava
2. In your own words, briefly explain how a caldera forms from principle types of volcanoes.
3. Recall from your reading about the nature of volcanoes, and in your own words, compare and contrast aa and pahoehoe lava in appearance and how they form.
4. Volcanoes are generally not preserved in the geologic rock record because they are usually eroded away. However, the various materials erupted from volcanoes are often found preserved in the rock record. From what you have learned about the different principle types of volcanoes, how could you infer what type of volcano erupted in a given area based on the type of volcanic deposits now found as layers of rock? Give specific examples, and briefly discuss how some materials may be linked to different types of volcanoes.
Your response should be at least 200 words in length.
5. In your own words, what creates Earthquakes? (75-word minimum)
