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 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.
Is porphyritic texture is not a feature of sedimentary rocks?
Correct, porphyritic texture is typically associated with igneous rocks and is not a common feature of sedimentary rocks. It is characterized by larger crystals, known as phenocrysts, surrounded by a fine-grained or glassy matrix. Sedimentary rocks are formed through the accumulation and lithification of sediments, which do not typically undergo the same crystallization processes as igneous rocks.
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.
How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
How are igneous and sedimentary rocks the same?
their both rocks
Are sedimentary and igneous rocks the same?
no
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.
What are the same about igneous metamorphic and sedimentary?
they are all rocks

Are all the rocks the same?
Yes, igneous, metamorphic, and sedimentary all can from from each other.

How does igneous rocks form?
Igneous rocks forms when molten rock cools&becomes solid. Igneous rocks that originally formed at great depths can reach Earth's surface over time. Deep rocks may be raised closer to the surface when mountains are pushed up.At the same time , other process can wear away the rocks that cover the deeper rocks
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.
