DAting Methods
1. What is relative dating? (hint: not when two cousins go on a date)
Relative Dating is sequence of events in which they occured.
2. When would a geologist use radiometric dating?
They use it to determine how old a rock is.
3. When would a geologist use radiocarbon dating?
They use it to determine how young a rock is.
4. Explain how you can use tree rings to date and study the recent past? (see p. 351)
They are valuable tool in the reconstruction of past evironments.
5. What is half-life?
Half life is amount of time it takes for half of a parent materials to turn into daughter material.
6. Explain how today's lab showed half-life.
Every penny that was heads up showed the parent and the tails is the daughter.

Destruction
What are potentially more dangerous to people: volcanoes or earthquakes? Why?
Volcanoes are because with earthquakes you can replace the stuff but with volcanoes everything burns.
Give three examples of major destruction from volcanoes or earthquakes. (Include the location of the volcano/earthquake, the date that it happened, what exactly happened, and a picture of each)
Hawaii Region, Hawaii, earth quake, and 3/9,2009
ECUADOR - Guagua Pichincha volcano 2/20/09
West Coast/Alaska Tsunami 11/15/06

3. What are three things that you learned?
A tsunami is sudden motion underground that causes a big wave, the motion that causes a tsunami could be an earthquake, a powerful volcanic eruption, and most of the tsunami's are cause by earthquakes.
4. What are two things that you found interesting?
Tsunamis are wave trains, tsunami races away from the epicenter, and that most of the time earthquakes are usually the motion that started a tsunami
5. What is one question that you still have?
What is a fault scrap?
1. Who is the author of your article?
no author is listed
2. Who is the publisher? (CNN, geology.com, USA Today, etc.)

3. What are three things that you learned?
The earthquake happened two years ago, the government is planning on rebuilding the school, and alot of earthquakes happen that destroyed 45 schools.
4. What are two things that you found interesting?
The fact that everyone is pitching in to help with the rebuilding, and the fact that they been funding this for a long time.

Mass Movement
Define mass movement.
Mass movement is the transfer of rock and soil downslope due to gravity.
What are the different types of mass movements?
Rockfalls, Slides, Slumps, Flows, and Creep
Which mass movement has the greatest potential to cause the most damage? Why?
Rockfalls
Include at least one picture of damage caused by your mass movement.
