CSULA Ocean Continent Convergent Plate Boundary Discussion Questions
Description
- Draw an ocean-continent convergent plate boundary in detail. Details required: show the layers of the Earth involved and label them with their names (oceanic crust, continental crust, mantle, lithosphere/plate, asthenosphere), arrow showing motion of the plates, the trench, the volcanic arc (volcanic mountain chain), and where melting
- Draw a divergent plate boundary in Details required: show the layers of the Earth involved and label them with their name (crust, mantle, lithosphere/plate, asthenosphere), arrows showing motion of the plates, the rift valley, and where melting occurs.
- Does the lava that erupts from volcanoes here on Earth ever come from the outer core? Explain your answer.
- Explain how each of the three rock types form, igneous, sedimentary, and metamorphic.
- Discuss uniformitarianism and give an example of how the concept is applied in geology.
- Edit
- What specific type of volcano is this? What kind of material does it erupt, ash or lava or both? What is the typical composition of the material it erupts, mafic, intermediate, or felsic? At what type of plate boundary is it typically found?
-
- What is this? What is its composition, felsic, intermediate, or mafic? How does it form?
- What specifically is the big fracture in the photo? What kind of stress created it? Was the rock brittle or ductile when it formed? What kind of rock do you think is present in this photo, igneous, sedimentary, or metamorphic? Explain
- What is this? What kind of stress created it? Was the rock brittle or ductile when it formed?
