1. A scientist would be able to tell the age of a tree by looking at its rings because the rings are the years that the tree has been there. Say for instance if you cut a tree down and you look at the middle you'll see a lot of light colored circles and for every line, it is a year.
2. This would be useful to scientist because besides rocks it also dates earths history.
3. I think this is an example of relative dating because of how the circle are in the tree and it looks like they are in order.

1. Cambrian
2. Ordovician
3. Slurian
4. Devonian
5. Mississippi
6. Pennsylvannian
7. Permian
8. Triassic
9. Jurassic
10. Cretaceous
11. Tertiarty
12. Quaternary

The acronym for these is: Cos Da Camel is Potentially Taking out Justice Comically on Terian Quadrant......to be continued...

diggin' for the earth's core:))

1. The world's deepest mine is 3.6 kilometers deep.
2. In order to get to the mantle you'll need to get through 35 km of rock.
3.  If my friends and I tried to get to China through the center of Earth, as we get to the mantle we would see hot rock, possibly some fossils...bones maybe...we will surely experience some muscle cramps, from digging, probably suffer heat stroke before we get to the end of the mantle. If we make it to see the outer core, you should know we'll get burned alive or we'll might just melt because the outer core is liquid hot metal.....keyword: HOT....anyway..if the suits we have on are so strong we can get to the inner core it still wouldn't help us get through, why? well the inner core is iron, I know of no tool that can get down there without melting and cut through the iron so we could get China....

Dear Mr. Dunn,

I THINK I SHOULD GET AT LEAST A B FOR ALL OF MY BLOGS FOR THIS QUARTER BECAUSE I DIDN'T REALLY MANAGE THEM ENOUGH.......BUT I WILL NEXT QUARTER. HOPEFULLY I'LL UPDATE THEM OFTEN, LIKE EVERYDAY AND CHECK ON THEM WHENEVER I GET THE CHANCE.(OH YEA, I DID THIS SO I CAN WORK ON MY CAPITALIZATION....::))

Rocks....rock!!!

1. The two types of igneous rocks are intrusive and extrusive. Intrusive are rocks that form underground. Magma is underground so the intrusive rock will most likely form from magma. Some examples of intrusive rocks are diorite, granite, and gabbro.Extrusive rocks are rocks that form above ground, probably from lava. Some examples would be obsidian and pumice.
2. The two types of metamorphic rocks are foliated and non- foliated rocks. foliated rocks are metamorphic rocks that have a layered or banded structure. non-foliated rocks aren't banded. some examples of foliated and non-foliated rocks are gneiss, slate, quarzite,and marble.
3. Two of the three main types of sedimentary rocks are clastic which are formed by mechanical weathering  debris. the other is chemical whic is formed by dissolved materials the precipitate from solution. Some examples of clastic and chemical sedimentary rocks are snadstone, shale, limestone, and rocksalt.
