ENV 111: key concepts in 6 slides…

How would you characterize this eruption? What does that suggest about the viscosity of the magma? Is this a relatively high- or low-temperature magma? Angle of slope? What type of extrusive rock would form here? What type of intrusive rock would form here? What are examples of minerals that would be found in these rocks? What minerals would not be found in these rocks? Where in the world do volcanoes often occur?

What is the relative speed of this stream? How would you characterize the following features of the sediment being transported: Size Shape Sorting Chemistry/mineralogy How would you measure the discharge of this stream? Where will these sediments end up? What’s occurring at this location? What’s occurring at this location? Why do these different processes occur, and what is the eventual result?

How do we classify mass movements? (3 criteria) What type of material moved? In what manner did it appear to move? How quickly did it move? What type of movement is this? What chain of events may have led to this movement? How exactly did water likely play a role? What can humans do to minimize such losses?

What is the name of this structural feature? What type of deformation has taken place here? Where in the earth did this deformation occur? What type of forces were involved? If brittle deformation had occurred instead, what feature would result? Where in the earth would this deformation occur? Where is the oldest layer?

How were these layers originally deposited? Where is the youngest layer? What caused the formation of the canyon? How fast was/is the river moving? Why are there apparent ridges that persist? What are the names of other landforms that form in this way?

What type of fault motion has occurred here? What forces result in such a motion? How can the magnitude of the EQ be assessed? How will the epicenter be located? Why can’t we predict very well when the next “big one” is coming? Where do earthquakes tend to occur in the world? Why?

Lessons from Day 1 (and hopes) You already know something about geology. (Now you know much more, and in more detail than before.) Geology is all around us. (You can provide many examples and can explain them.) Geology has relevance to our lives and surroundings. (You understand processes well enough to support this statement.) There is a lot more to learn! (Still!)
