What else can I help you with?
All rocks are made of sediments?
Not all rocks are, only sedimentary rocks are truly made up of sediments. Some metamorphic rocks do because they are formed when heat and pressure are applied to sedimentary rocks, which makes sediments the basis of these rocks as well
How does the Rocks Cycle classify rocks?
The rock cycle classifies rocks into three main categories: igneous rocks, formed from the solidification of molten rock; sedimentary rocks, formed from the compaction and cementation of sediments; and metamorphic rocks, formed from the alteration of existing rocks through heat and pressure.
How are igneous rocks and metamorphic rocks similar?
Igneous rocks and metamorphic rocks both form within the Earth's crust. They are both created through the process of solidification, although igneous rocks solidify from molten magma while metamorphic rocks form from the alteration of existing rocks through heat and pressure. Both types of rocks can be found in a wide range of geological settings.
When you look at a metamorphic rock how can you tell it is one?
Understand that metamorphic rocks are those that have changed in some way by heat or pressure or both. Sedimentary rocks are formed from sediments and igneous rocks are formed by fire. When these rocks change again, they become metamorphic. Marble is one type of metamorphic rock.Look at the way the grain are formed. In schist rocks, you can see that the layers and the grains all go the same way. Warning Metamorphic rocks are difficult to classify because different amounts of heat or pressure to the same rock can look different.
Can any stone start out as metamorphic?
No, not all stones can start out as metamorphic. Metamorphic rocks are formed from existing rocks that undergo high heat and pressure, so they must have a pre-existing rock to transform from.
What forces are in the rock cycle?
Sedimentary rocks are formed when other rocks (igneous, metamorphic, or sedimentary) are weathered and eroded and their sediments are compacted and cemented together. Metamorphic rocks can be formed when heat and pressure is applied to any type of existing rock. Igneous rocks are formed when magma cools. The magma can be made up of melted rocks of any kind (sedimentary, igneous, or metamorphic). The cycle repeats itself all the time and all of the rocks can come from any other kind of rock.
Can heat and pressure change other types of rocks into a metamorphic rock?
Weathering changes it to a sediment and compaction changes it to a sedimentary rock.
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.

Where are you likely to find all three types of rocks being formed and changed?
You are likely to find all three types of rocks being formed and changed in the Earth's lithosphere, particularly at plate boundaries where tectonic forces create igneous rocks through volcanic activity, metamorphic rocks through intense heat and pressure, and sedimentary rocks through the accumulation and compression of sediment over time.
How are rocks classified put in groups?
Rocks are classified into three main groups based on how they are formed: igneous rocks (formed from the cooling of molten rock), sedimentary rocks (formed from the accumulation and cementation of sediment particles), and metamorphic rocks (formed from the alteration of existing rocks under high heat and pressure). Each group has various subcategories based on specific characteristics and composition.
What rock is formed from pieces of other rocks?
Sedimentary rock is formed from pieces of other rocks, minerals, and organic materials that have been compacted and cemented together over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
What three factors can create metamorphic rocks?
there are not three factors. Metamophic rocks are formed by heat and pressure. the heat sort of melts it slowly while the pressure compacts it.
