classic rocks are not minerals. limestone is
Classic sedimentary rocks are made up a minerals, grains, and rock fragments from older rocks. Some examples of this kind of rock are sandstone, breccia, and shale.
Classic examples can be found on the Jurassic Coast in Dorset, England.
When sedimentary rock undergoes enough heat and pressure, it becomes metamorphic rock. A classic example of this is when shale becomes slate.
Sediments.......to create a sedimentary rock.....
Some are, yes. But broadly speaking, sedimentary is rock made of sediment, which can be far smaller. A classic example of a rock/pebble rock is conglomerate.
igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
You can find "skipping stones" from any of the classic rock formations: sedimentary, igneous, metamorphic, and mineral. The only criterion is a good skipping stone needs to be round and a thickness much thinner than the width and height.
A classic way to disprove evolution by means of fossils would be to find a fossil rabbit in Pre-Cambrian sedimentary rocks. Of course, that can never happen.
sedimentary, the oil is formed within a source rock formed with high quantities of decomposed vegetation, then a reservoir rock which holds the oil and a capping rock which seals it shut in addition to this sequence of rocks, certain structures are required to stop the oil escaping, a classic would be an anticline
The Burren is a region in Ireland known for its limestone bedrock, which can be easily eroded by water, creating underground rivers and caves. The presence of these features is due to the processes of erosion and dissolution that have taken place over thousands of years, shaping the unique landscape of the area.
