Week 10:

 

1. The big question addressed in lab, and a description of what you did.
1. In lab, we spent some time discussing rocks and the types of rocks. The big question we focused on was: What is a rock? We used starbursts to create the 3 different types of rocks: Igneous, sedimentary, and metamorphic. We also spent some time discussing the structure of the earth: the solid core, liquid mantle, and the crust.
   
   
   
2. A description of what you learned in Thursday's lecture.
1. In lecture, we discussed rock types and the law of superposition. The law of superposition states that the rocks at the bottom are the oldest and the rocks at the top are the newest. That follows pretty true unless theres is a fault or dyke.
3. Answer questions about the weekly textbook reading:
   1. What did you learn?
   1. I learned about the types of plates on the earth and the different landforms that can come about with them. When two continental plates converge, the land is pushed into each other and forms a mountain. When to oceanic plates converge, one plate is subducted under the other and a trench or island arc is formed. When a continental plate converges with an oceanic plate, the denser oceanic plate is subducted and can form volcanoes and mountain ranges. When there is a divergent pate, it creates a mid-ocean ridge or a large crack in the land.
   2. What was most helpful?
   1. I found the video about the structure of the earth to be the most helpful in letting me visually see the structure of the earth.
   3. What do you need more information on?
   1. I need more information on how earthquakes start to form. 
   4. What questions/concerns/comments do you have?
   1. I am questioning everything honestly, what causes these plates to converge????
