What else can I help you with?
What is one way igneous sedimentary and metamorphic rocks are different?
igneous rocks are made of lava that cools and hardens and metamorphic rocks are madeby heat and pressure.
What ia an igneous rock?
An igneous rock is the only type of rock out of the 3 (igneous,sedimentary and metamorphic) in which it is formed out of pure lava. So, when a volcano spews lava (or magma), it cools and hardens, becoming igneous rock (pretty simple process).
What kinds of formations are created when cools and hardens?
Igneous Rocks are formed. Obsidian is a volcanic glass, go to wikepidiea and search "list of rocks" and it will come up with all the different igneous, metamorphic, and sedimentary rocks and what they are.
How does the metamorphic rock change into a igneous rock?
metamorphic rock melts into magma and volcano erupts. lava hardens and cools
How can a metomorphic rock become an igneous rock?
Metamorphic rocks underground melt to become magma. When a volcano erupts, magma flows out of it. As the lava cools it hardens and becomes igneous rock.
Is granite is a igneous sedimentary or metamorphic?
the granite melts into lava then cools becoming igneous. it erodes into sediment and then gets compressed into a sedimentary rock. the sedimentary rock becomes metamorphic with heat and pressure deep within Earth
What rock is formed when molten or liquid matter from inside the earth comes to the surface cools and hardens?
Depending on the heat either a igneous or metamorphic rock. If hotter then igneous then if cooler metamorphic
What are the different classes of rocks called?
If you mean the different types, there are sedimentary, metamorphic, and igneous. Sedimentary is formed when layers and layers of sediment are cemented together. During the process of metamorphism, no new substance is formed. The rock is compressed by heat or scolding water, and pressure. That is how metamorphic rock is formed. Lastly, igneous rock is formed when magma and/or lava cools and hardens. An example of sedimentary rock is limestone. A metamorphic, slate. A good example of igneous is granite, and everyone knows what that is.
Scientists divide rocks into groups based on what?
Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.

How different rocks are formed?
Rocks can be formed by particles of pebbles, sand or shells creating sedimentary rocks. When molten rock cools and hardens it will form igneous rocks. When there is pressure and intense heat on rocks, they form metamorphic rocks.
How does sedimentary rock form to metamorphic rock?
Shale (a metamorphic rock) goes through heat and pressure than it turns into slate (a sedimentary rock)
What rocks form when magma cools and hardens?
Igneous rock is what forms when magma cools and hardens.
