What else can I help you with?
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.
What do different rock textures of metamorphic rock reflect?
The texture would reflect the degree and type of metamorphism which had led to its formation. Rock can experience various stages of metamorphism in its evolution depending mostly on changes in heat or pressure. Texture is also dependent on the composition of the protolith, or parent rock.
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.
Why can two igneous rocks have the same minerals but different names?
The rocks may have different textures
What are the two main families of rock forming minerals?
The two main families of rock forming minerals are silicate minerals and non-silicate minerals. Silicate minerals are the most abundant and include minerals such as quartz and feldspar, while non-silicate minerals include groups like carbonates and sulfates.
What are 2 textures of metamorphic rock?
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.

What is a rock with two different textures called?
Porphryitic igneous rock is composed of phenocrysts embedded in a finer matrix.
Does Metamorphic rock has different kinds of textures?

How many syllables in the word textures?

What do different rock textures of metamorphic rock reflect?
The texture would reflect the degree and type of metamorphism which had led to its formation. Rock can experience various stages of metamorphism in its evolution depending mostly on changes in heat or pressure. Texture is also dependent on the composition of the protolith, or parent rock.
When magma cools rapidly what kind of textures does rock have?
Aphanitic, or fine-grained.
A laccolith is an example of a(n) igneous rock (one of the two main igneous rock groups).?
intrusive
What are 2 main uses of rocks?
Two main uses of rock are using them for building materials and industrial processes.
