Trees.

Scientists can tell the three by the rings because ever year it gets older one more ring gets added. It may because it tell us how old it is or maybe the past and how long the earth been around. Also it tell us how old trees can get. It absolute dating.

Rocks! unconformity...?

The order of the rock is D, A, E, C, B. From oldest to youngest. Unconformity really means the order of rock from oldest to largest.

Volcano...

I think volcano are far more dangerous then earthquake. I feel this way because is Chile they had a massive volcano eruption. It was the Chile Chaiten volcano. This volcano erupted May 3, 2008. And other than that scientists have been studying volcano and they have came up with a thesis that volcano can erupt much more quickly then anyone thought.

Wow!

I think I deserve a 93% because I could have done better. Next time can't do them less minute. It's very hard so don't try.

Dreams

The world's deepest mine is Tautona and its 3.6 kilometers deep. I would dig far enough to say I tryed but didn't succeed and also to keep myself. If could ever dig a hole to the mantle it would look like hot melt iron. It would be bright like the sun. The amazing thing I could see the inner core would be spinning. And the outer core would be a pool of water. As i approached the other side it would just normal like here in Fayetteville but more fun.

Grades.?!

I think deserve I a 88%. I think I deserve this because I tryed and work hard. I did the best I could do. I turn most of my work time. Nice, neat, and clean. Also I did pretty well on my tests.

The two main types of Igneous Rock are intrusive and extrusive rock. Intrusive is below Earth surface. And Extrusive is above Earth surface. Two main types of Metamorphic are Foliate Metamorphic Rock and Non-Foliate Metamorphic. Foliate Metamorphic Rock is layed or branded appearance that is produce by exposure to heat and directed pressure. But, unlike Foliate Metamorphic Rock Non-Foliate doesn't have a branded or its not layed. Two types of Sedimentary rocks are Chemical Sedimentary Rock and Organic Sedimentary Rock. Chemical Sedimentary Rock form when dissolved materials precipitate from solution. Organic Sedimentary Rock form from accumulation of plants and animal debris.
