1) Visit

http://landslides.usgs.gov/ (Links to an external site.)Links to an external site.

Poke around on the website (OR ON OTHER WEBSITES) and find either an interesting event or perhaps a landslide event that happened near where you live and then answer the following:

When? Where? How far is this from your home? Type of mass movement? Triggered by? Loss of lives? Financial impact?

2) What is the difference between chemical and mechanical weathering?

3) A shale layer on a mountainside in the Canadian Rockies of British Columbia opened a window on a fantastic interval in the history of life, around 540 million years ago.
Read about it—

A) Consider how shale forms. Why is shale often a better rock type for preserving fossils than say sandstone or conglomerate?

B) What sort of “depositional environment” is represented by the Burgess Shale?
(Definitely make sure that you look up, and understand, the use of the term “depositional environment” before answering this question.)

4) Very slow mass movement is called creep. How slowly can creep occur (e.g. meters/yr, feet/yr, millimeters/yr)?

5) Bouldering on Flagstaff Mountain (near Boulder, Colorado) takes place on the Fountain Formation. It is a combination of what detrital sedimentary rock types?

6) After viewing the entire group of “Geology Rocks” video segments, explain what sort of features associated with the Fountain Formation suggest that it represents the erosion of an ancient mountain range.

7) For a rock to be considered truly metamorphic, it must have undergone ______ .

A) melting B) recrystallization C) extreme pressure D) cementation

8) If a rock undergoing metamorphism reaches a temperature high enough to initiate partial melting, what sort of rock is formed?

9) Go to the web and look for information on the geology of mars.
You might try http://mars.jpl.nasa.gov/ (Links to an external site.)Links to an external site. But there are many other sites. And, you can also use the final chapter of your textbook on planetary geology.

What is the evidence for either modern or ancient LIQUID water on mars? Explain.

ahh the challenges of online internet web research! what to believe?? 🙂

10) OK,,, You can use your text for starters, but you will undoubtedly need to do some (good!) web research to answer the following.
Remember, the internet is filled with “information” but one has to identify trustworthy sites!
Questions:
A) Titan is a satellite (moon) of what major planet?
B) Is there some form of liquid on Titan? If so, what?
C) Is there any evidence for sedimentary rocks on Titan? (or would we even expect them?)

For this question you MUST list your source(s). If you do not do so, I will deduct points.
