Rock #3

What should go in your blog entry:

Describe the geological feature itself (what it is, size, etc.).  Is it experiencing erosion now, or was it mostly in the past?  What was the cause of the erosion? (Water flow, gravity, etc.)

I found this rock on the Morro Bay beach, in the sand near the water. It is about the size of a golf bal, but is not a perfect ball shape. Smooth edges with a gray base and white colors within it, as well as little black and brown spots. I think that this rock is a sedimentary rock and is a combination of small compounded rocks. Lots of heat and compaction of rocks has created this rock that I have found on the beach. 

What evidence tells you that erosion has occurred?  Estimate how long you think the erosion has been happening.  How far was the sediment transported?

In the rock, there is a main part that is a grayish color. In that rock, there are lots of little specks from that, indicating that is is a sedimentary rock and an erosion has already occurred. I think that this erosion happened a long time ago based on the fact the rock is so smooth and has not sharp edges. I believe that it has had a lot of weathering over the years.

  I walked out of my dorm on Friday night on the way to dinner, and saw this cool looking rook on the walkway! It has a rough outside with lots of different colored specks that made it look like the sidewalk. The picture was taken on Friday April 4th outside the Yakitutu building. The first picture was taken later this evening as I was analyzing the rock!

     This Weekend I went to Avila Beach and found this cool rock!  Describe the geological feature itself (what it is, size, etc.).  Is it experiencing weathering now, or was it mostly in the past?  Do you think it was chemical or physical weathering?  Explain how you think the weathering happened. The size of the object is about the size of a baseball, however not round but with lots of sharp edges. One of the sides is very flat, making me think that it was maybe split at one point in time? I think that the weathering on this rock has been recent, due to how smooth the sides of the rock are as well as that sharp split on that one edge. I think this shows that it is a physical weathering process.  What evidence tells you that weathering has occurred?  Estimate how long you think the weathering has been happening. The big slash on the one side of rock is something that indicated this rock has gone through weathering. It has had something physi...
