What a rock cycle

One type of rock changes another type under certain conditions in a cyclic manner. This process if transformation of a rock from another is know as rock cycle

The process of transformation of the rock from one to another is known as Rock cycle

The process of conversion of rock from one type to another type of rock under certain conditions in a cyclic manner is called as rock cycle

The Rock Cycle Rocks are constantly changing in what is called the rock cycle. It takes millions of years for rocks to change. Here is an example of the rock cycle describing how a rock can change from igneous to sedimentary to metamorphic over time. Rock cycle example 1. Melted rock or magma is sent to the earth's surface by a volcano. It cools and forms an igneous rock. 2. Next the weather, or a river, and other events will slowly break up this rock into small pieces of sediment. 3. As sediment builds up and hardens over years, a sedimentary rock is formed. 4. Slowly this sediment rock will get covered with other rocks and end up deep in the Earth's crust. 5. When the pressure and heat get high enough, the sedimentary rock will metamorphose into a metamorphic rock and the cycle will start over again. One thing to note is that rocks don't need to follow this specific cycle. They may change from one type to another and back again in practically any order.
