The Rock Cycle

The Rock Cycle is the continual process by which new rock forms from old rock material. This process is used with rocks and their never changing matter. Scientist defines a rock as a natural occurring solid mixture of one or more minerals and organic matter. This certain geological process shapes the features of our planet and influence the type of rock that is found in a certain area. The process in which water, wind, ice and heat break down rock is called weathering. Weathering is important because it breaks down rock into rock and mineral fragments, which are sediment and from most sediment rock is made. If the temperature and pressure are high enough at the bottom of the sediment, the rock can change into a metamorphic rock. Sometimes, if the rock gets hot enough, it will melt creating the magma that eventually cools into igneous rock. This is the result of the rock cycle and heat and pressure. The rock cycle is a continual process, as said in the definition. Uplift is the movement within the Earth that causes rocks inside the Earth to be moved to the Earth's surface. When the rock reaches the Earth's surface, deposition, weathering, and erosion begin. This fuels the rock cycle, making it a continuous process. The rock cycle goes in a circular motion, making it have no starting place or ending place. One of the places on the rock cycle is weathering, then erosion, then deposition, then compaction and cementation, then metamorphism, then melting, then cooling, then solidification, and then it goes agian.
