There are three main types of rocks: igneous, sedimentary, and metamorphic. Each of these types of rocks are formed in unique ways and each type of rock can be changed into each of the other types of rock. Geologists call this process the rock cycle. Essentially the rock cycle is the process that makes and recycles rocks.
Most rocks on earth began as igneous rocks. Igneous rocks are formed from magma. Magma is melted rock beneath the Earth’s surface. Magma cools and solidifies into rock. When igneous rocks are exposed on the surface, time and weather break the rock down into smaller and smaller pieces. This process is called weathering and erosion. Wind and water carry the smaller pieces of igneous rocks into piles called sediment beds. Over time the sediment beds get buried and the pieces of rock become cemented together to form a new type of rock called a sedimentary rock.
If a sedimentary rock gets buried deep in the Earth, heat and pressure essentially bake the rock, changing it into something new. This process is called metamorphosis, and the new rock is called a metamorphic rock. Metamorphosis can happen to igneous rocks as well. In short, the rock cycle is the name for the rocks and the processes that form them.
For sedimentary rocks the processes are cementation (cemented) and compaction (packed). To form igneous rocks the process is melting and hardening. Heat and pressure form metamorphic rocks.
The rock cycle can start with any rock type and be changed into any rock type depending on the processes that act on it.

This is in my science do now
true
What should a model of the rock cycle shows as the process that changes sedimentary rock to metamorphic rock?
heat and pressure
Which process would change metamorphic rock to igneous rock?
melting followed by cooling
1Gravity can cause magma within Earth to 2 rise, resulting in the formation of 3 igneous rock.
Which type of rock contains fossils? Select the correct answer.
sedimentary rock
you guys do not have to be mean did you guys come here for the same thing to not do your work I came here for help
no
Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
that question was in my son's science packet
What is the characteristics of the three type of rock
The meaning of igneous is related to rocks that are formed from magma, which is melted rock beneath the Earth's surface. When this magma cools and solidifies, it forms igneous rocks.
The meaning of sedimentary is related to rocks that are formed by the accumulation and compaction of sediment. Sediment can consist of rock fragments, mineral particles, and even the remains of plants and animals. Over time, this sediment is buried and becomes compacted, forming sedimentary rocks.
The meaning of metamorphic is related to rocks that have undergone a process called metamorphosis, which involves the alteration of their texture, mineralogy, and sometimes even their chemical composition. This alteration is caused by heat and pressure deep within the Earth's crust, resulting in the formation of new rocks with different characteristics from their original state.
The meaning of rock cycle refers to the continuous process through which rocks are formed, transformed, and recycled on Earth. It involves the different types of rocks (igneous, sedimentary, and metamorphic) being subjected to various geological processes such as weathering, erosion, melting, solidification, heat, and pressure. The rock cycle describes how any rock type can be changed into another rock type over time.
The meaning of compacted refers to the process of sediment particles being pressed together, reducing the space between them. In the context of sedimentary rocks, compaction occurs when layers of sediment accumulate over time, and the weight of the overlying layers causes the lower layers to become tightly packed, leading to the formation of solid sedimentary rocks.
