Sedimentary is formed by the sediments collecting, compacting and cementing together. Metamorphic rocks are made when rocks are compacted and exposed to heat and pressure. The only rock that is made of cooled hardened magma is an igneous rock which can be made two ways, intrusively or extrusively.
What else can I help you with?
Why do the three rock groups contain the same basic composition?
All rocks are some arrangement of Earth's magma. Igneous rocks are hardened magma. Sedimentary rock are from weathered material from igneous, sedimentary, or metamorphic rocks. Metamorphic rocks have the same composition but are subject to extreme heat and pressure and hence change their crystal structure.
What are two ways sedimentary and igneous rocks can be changed into metamorphic rocks?
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
Are metamorphic rocks more dense than sedimentary or igneous rocks?
Igneous rocks are denser than sedimentary rocks because the particles and materials making up the igneous rock are more closely packed and compacted making more matter able to fit into a tiny area of its structures.
What is the full cycle of rocks?
The rock cycle is basically the biography of a rock. It is important to keep in mind that any type of rock can turn into any other type of rock depending on the external forces. Let's start with a grouping of sediments. Through lithification (cementation), those sediments become a sedimentary rock. That sedimentary rock is then exposed to an intense amount of heat and pressure, which turn it into a metamorphic rock. That metamorphic rock is then melted at extremely high temperatures to make magma, which then cools to a solid state to create an igneous rock. That igneous rock is exposed to wind, water, ice, etc. and is weathered and eroded back into a grouping of sediments. From there, it starts all over again. This cycle continues and can start from any stage. An important fact is that each rock can become a different rock of that same type. For instance, an igneous rock can be remelted and recooled to form a different igneous rock. The same holds true for metamorphic and sedimentary rocks.
What causes sedimentary and igneous rocks to change?
Sedimentary rocks can be changed into metamorphic rocks through heat and pressure, while igneous rocks can be changed into metamorphic rocks through the same process. Both types of rocks can also be weathered and eroded, leading to the formation of new sedimentary rocks.
How are the sedimentary rock the metamorphic rock and the igneous rock the same?
They all contain minerals.
What are the same about igneous metamorphic and sedimentary?
they are all rocks
Can metamorphic rocks be sedimentary or igneous rocks?
there are several ways such as heat & pressure, melting, chemical weathering, compression, compaction & cementation, but it depends on the kind of rock it is for what process it has to go through. -Cutegirl99
Is sedimentary rock the only type of layered rock?
No. Extrusive igneous rocks are usually layered. Some metamorphic rocks have foliation, which resembles layering, but it is not the same thing.
How is the movement of Earth matirials during a flash flood the same as the movement during normol flow?
it keeps on flowing around igneous rock and metamorphic rock and also sedimentary rock
What are 2 things the same about igneous and sedimentary rocks?
Both are composed of minerals. Some sedimentary rocks contain pieces of igneous rocks.
Why do the three rock groups contain the same basic composition?
All rocks are some arrangement of Earth's magma. Igneous rocks are hardened magma. Sedimentary rock are from weathered material from igneous, sedimentary, or metamorphic rocks. Metamorphic rocks have the same composition but are subject to extreme heat and pressure and hence change their crystal structure.
What are two ways sedimentary and igneous rocks can be changed into metamorphic rocks?
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
Are all the rocks the same?
Yes, igneous, metamorphic, and sedimentary all can from from each other.
Is a sedimentary rock or a metamorphic rock harder to sculpt?
Metamorphic rocks are formed from sedimentary and igneous rocks. When sedimentary or igneous rock is subjected to heat and pressure, the rock gets compressed. Therefore, if you had the same amount of metamorphic rock and sedimentary or igneous rock, the metamorphic rock would be heavier, because there is more 'stuff' in the metamorphic rock. ---------------------------------------------- However please note: There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.
What type of rock does NOT belong in the same category as the others?
Sedimentary rock does not belong in the same category as igneous and metamorphic rocks because it forms from the accumulation and compression of sediment over time, while igneous rocks form from cooling magma/lava and metamorphic rocks form from the alteration of existing rock under high heat and pressure.
How do sedimentary rock change metamorphic?
Sedimentary rocks change to metamorphic the same way any other rock would: through heat and pressure.
