Tectonic plate’s movement creates ocean basins, mid-ocean ridges, through collision. Colliding plates push sedimentary materials into an uplifted mass of rock that contains numerous folds and faults. The Earth has undergone a number of mountain building periods. The process of creation is first by the accumulation of sediments then the tectonic collision causes rock deformation and crystal uplift and finally the isocratic rebound continues to cause uplift despite erosion and causes the development of new mountain peaks through block faulting.…
Another way that sediments form from igneous rock is when things like acid chemically break them down. This happens with limestone. Another way sediments are formed from igneous rock is through the process of dead plants coming together. Such is the case with coal.…
Sedimentary rocks- rocks made up of pieces of other rocks. We call the pieces of rock "clasts" (Clast means "broken piece"). A clast is a piece of rock broken off of another rock.…
The rock cycle is something that a lot of people know. There are a lot of different versions. Some are more complicated than others(OI). The rock cycle can take thousands of years to complete(OI)! Every rock can turn into another rock from every stage(Doc.1). Geology is not just studying boring rocks. There is a lot more to it. You can study rocks to find out how old the rock is or even how old the earth is. You could be the person to find out how long ago a dinosaur by what rock the bones were in. Or maybe you find a fossil of a new type of animal and the rocks can tell you when it lived. Rocks can be a whole lot more exciting than you ever thought.…

The material on the right, the gneiss – looks quite different to the peridotite. That would suggest that we may have different minerals – and different minerals mean different environment and or/different processes. The gneiss is a metamorphosed rock – so a rock that has been transformed from its original form due to heat and or pressure. Gneiss makes up most of earths lower crust – the pressure and heat transforms sedimentary and igneous rocks.…
The most common sedimentary rocks in the park are from the Dakota sandstone formation. It is exposed in many places throughout the Rocky Mountain region and extends from New Mexico northward for 1,000 miles or more. It is prominent because the sand is cemented together firmly to form a quartzite which resists erosion very well. There are also rocks from the Morrison formation, which is composed of mudstone, sandstone…
The different types of rocks like igneous, sedimentary, and metamorphic have to go through a process to become that type of rock. Igneous is formed when magma is cooled and hardens. Metamorphic rocks are the exact opposite, the rock is formed under the earth's surface, when heat and pressure are added. Lastly, sedimentary rocks are formed by sediments being pressured together over time. Some features of the rock are, that the sediments can be seen, there are ribbon like layers, crystals, and wholes. None of these thing would be here without plate tectonics. How would metamorphic rocks get under the earth's surface or where would the magma and sediments come from to complete the process? Rocks can not…
Sandstone is made of layers of sediment, so it can be easily identifiable by looking for layers of sediment. Sedimentary rocks are made from broken pieces of other rocks and then cemented together to form a new rock. Sandstone has grain-sized particles from broken, older rocks and minerals. The grains gather and the pressure from the sediments above and the movement of water push the grains together and becomes…
The crystals form a sort of glue that sticks or cements the pieces of rock together. This process is called cementation.…
For example, the presence of sedimentary rocks all over the world indicates that there had been global water activity. In order for the sedimentary rocks to form, there must be erosion, transportation, and deposition of sediments by moving water that contained the sediments. After the sediment has been deposited, it will slowly convert into stone. In addition, fossils have been discovered within the sedimentary rocks. Fossils could not have been preserved in the rocks unless the deposition process was expeditious. The mere existence of fossils in sedimentary rock is evidence that these rocks were formed by an aqueous catastrophism. There has been a question of whether the rocks were formed by multiple local catastrophes over several ages, or by a great number of local catastrophes in a single age. It is more likely to be in the single age because each stratum was laid down quickly, implying consistent water flow conditions. Such uniformity is not prolonged, meaning each layer was deposited in rapid succession otherwise there would be evidence of inconsistency. (Geology and the…
