Eroded rock
Erosion is the process in which eroded pieces of rock are left in a new place. Rock is removed from the earth's surface due to natural causes such as wind or water flow.
By Chemical weathering
This is called an unconformity...
Beacon Rock is not a volcano, but rather a volcanic plug. It was formed from the solidified magma that filled the vent of an ancient volcano.
It is an extrusive rock from a former volcano. The cone around the solidified metamorphic core eroded away over time, leaving only the center rock seen today.
since igneous rocks are more dense than the other two rock types, they will not as easily erode away and hence maintain the structure of the ancient volcano
disconformity
Igneous rock can be found on the surface in areas of current or past volcanism or in uplifted and eroded areas of past plutonic intrusions, deep underground nearly anywhere, or in areas of past or present glaciation, where igneous rock has been eroded and deposited.
A volcano rock is rock formed from ash or lava erupted from a volcano.
== == After a rock has been eroded you will find dirt,sand,rock and occcasionally silk.
Eroded rock
We call them clastic rock also referred to us the sedimentary rock.

Rock conduit that remains when the surrounding cone has been eroded is the volcanic neck.
Any rock outcropping at a shoreline.
