What are two different igneous rock textures?
*fine-grained *coarse-grained
What is a rock with two different textures called?
Porphryitic igneous rock is composed of phenocrysts embedded in a finer matrix.
What are 2 textures of metamorphic rock?
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
What are two types of igneous rocks?
Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.
What is the texture of Intrusive igneous rocks?
Intrusive igneous rocks have a coarse-grained texture because they cool slowly beneath the Earth's surface, allowing larger mineral crystals to form. These rocks often have interlocking crystals that are visible to the naked eye due to their slow cooling process.

A lava flow is an example of an igneous rock one of the two main igneous rock groups?
It is an example of extrusive igneous rock.
Why can two igneous rocks have the same minerals but different names?
The rocks may have different textures
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.
One of two ways that sedimentary and igneous rocks can be changed into metamorphic rocks?
Sedimentary rocks can be changed into metamorphic rocks through heat and pressure, typically from tectonic forces or deep burial. Igneous rocks can also be metamorphosed through increased temperature and pressure, causing mineral recrystallization and the development of new textures and structures.

Is it possible for two igneous rocks to have the same mineral constituents but different names?
Yes, it is possible for two igneous rocks to have the same mineral constituents but different names. This can occur if the rocks have formed under different conditions such as depth of burial, cooling rates, or chemical compositions, which can lead to different textures, structures, and overall classification.
What are the types of volcanic rocks?
Igneous rocks exhibit three types of textures: coarse grained (intrusive), fine grained (extrusive), and porphyritic (two-stage solidification of mineral constituents). Chemically, they are categorized as felsic, mafic, or intermediate.
What are two possible fates for a igneous rock?
Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.
