GG/ERTH 101 Introduction to Geology/Dynamic Earth Answer any five from the below questions for me
GG/ERTH 101 Introduction to Geology/Dynamic Earth Answer any five from the below questions for me.
1. Minerals — beautiful! (a) Definition (as used in class)? (b) Please list five physical properties of a mineral that were discussed/shown in class that are used to identify different minerals.
2. Plate Tectonics - What is Hawaii's origin in the plate tectonics story, and what criteria support that origin?
3. Plate tectonics — what a story! But what it is based upon? What physical criteria occur on this earth, and not on Venus or Mars, that substantiate this idea? Describe three.
4. Bowen's Reaction Series neatly explains why we have different types of igneous rocks originating from subsurface magma chambers — how does this work assuming no complications to the process?
5. Bowen's Reaction Series... on this planet there are a number of complications that interfere with the process going smoothly to completion -- describe two such complexities.
6. Explosive volcanism... deadly. Why do volcanoes explode rather than erupt more benignly such as here in Hawaii — describe two reasons.
7. Types of volcanic eruptions... Usually one type is characteristic of a particular volcano and constructs a volcanic edifice with a characteristic shape... thus if a volcano is threatening to erupt we can predict (and hope) that the eruption type will be like those of past eruptions = a predictive tool on what to do — run, or wait and see. With that in mind, contrast the characteristic eruption styles of these two volcanoes that are threatening to erupt: Mauna Loa and Mt. Vulcano (in Italy).
8. Pyroclastics are the product of explosive volcanism — what are they composed of, and name four types of pyroclastic particles.
