Sedimentary Rock
Sedimentary Rocks
This is a picture of a sedimentary rock. I want to talk about how this rock was formed and the erosion that took place until the rock crumbled.
The first thing that I noticed from these pictures was that the rocks location was on an ocean side. The lithification (or process of becoming a rock) of this rock seems to originate from the conglomeration of sediments thus creating the sedimentary rock, sandstone. One can see this by first noticing the location of the rock. It is located in a region where there is lots of wind and by being at the base of a river, there is high action of water. With all of these factors contributing to the deposit of sediments, they gathered, conglomerated, and over time this sedimentary rock was created. In the pictures, I noticed that at the base of the rock there are what appear to be small, gravel-like fragments. These fragments further support the notion that the rock is sedimentary (Western Development). Even more support for this would be that of the erosion rate. Sedimentary rocks are not the most structured rocks, in which they tend to break apart at faster rates then other rocks
