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 rock's 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 such as igneous rocks. .
This sedimentary rock is affected by all of the spheres of influence. The rock itself is composed of small fragments from the lithosphere. These fragments conglomerated from different means such as the movement of water, which in turn shows one way in which the hydrosphere affected this rock. The hydrosphere also affects the rock by means of glaciers. Maybe not in this picture, but some sedimentary rocks are affected by glaciers. This happened by glaciers running into the rocks, thus causing some deterioration. .
Another sphere, which has influenced the rock is that of the biosphere. I would venture to say that some animals make their home in the cracks of the rock. People try and preserve some sedimentary rocks (McCarthy, 1999).
The atmosphere has also influenced the rock by the affect its affect on weathering.
