What can I do

1. List all of the geologic periods in order from oldest to current.
Quaternary, Tertiary, Cretaceous, Jurassic, Triassic, Permian, Pennsylvanian, Mississippian, Devonian, Silurian, Ordovician, Cambrian.


2. Since the extra credit question is so hard, come up with a mneumonic to help you remember it.
Make a rap

Hack'n hol (the hack of the hol)

1. How can scientists tell the age of a tree by looking at the rings? Explain what that means.
Each year a tree gets a new ring telling the age:each ring equals a year



2. How/why would this be useful?
This can be useful because lets say there was a tree thats has be there for quite and you want to see how old the tree is you just simply count the rings




3. Is this an example of relative or absolute dating?
This is an example of absolute dating




4. Provide a picture or a tree ring sample.

Lets dig a hole!!!!!!! ;)

1. How deep is the deepest mine in the world?

The deepest mine in the world is 3.6 kilometers.


2. How deep would you have to dig to reach the mantle?
You will have to dig down 35km to the mantle.




3. Let's pretend that you and your friends tried to dig a hole in your backyard to find a shortcut to China. The thing is, you guys had special suits that could withstand extreme temperatures, so you would not die. If you were somehow able to reach the mantle, what would it look like? What kinds of things would you see? How about the outer core? Inner core? What would it look like as you approached the surface (the crust) on the other side?

Well I will might see dirt, magma, iron, nickel,and other metals. When I reach China I would make people pay $50 to go in my hole.

Intursive and extursive rocks are two types of igneous rocks.Igneous rocks form when magma hardens underground.an example is the Obsidian . Obsidian rocksi s a dark-colored volcanic glass that forms from the very rapid cooling of molten rock material. It cools so rapidly that crystals do not form. A Basalt t(to the left) is a fine-grained, dark-colored extrusive igneous rock composed mainly of plagioclase and pyroxene. Extrusive rocks from when lava hardens.

Most metamorphism form when elevated tempertures & pressure and forms a few kilometers below earth's surface. The two basic type of metamorphic rocks are foliated metamorphic rocks and non-foliated metamorphic rocks. Foliated rocks are a layered or banded appearance that is produced by exposure to heat and directed pressure, and non-foilated do not have a layered or banded appearance.

Sedimentary rocks are formed by the accumulation of sediments. The three types of sedimentary rocks are clastic sedimentary rocks which are that are formed from mechanical weathering debris. Another sedimentary rock is chemical sedimentary rock which is forms when disolved materials precipitate from solution. The thrid one is organic sedimentary rocks forms from the accumulation of plant or animal debris.

whats on my mind

I think that I deserve an 100% for my blogs because I put all my work into these blogs and if I got anything less then a 90% something is wrong. I think that my blogs are great and I put my opinions into them and they were great. In my blogs I put pictures or a vivid description.I'm not saying my blogs are the best but they are not the worst ,these are the reason i think my blogs should get an A
