What is the size of crystals in an igneous rock called?
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
What is a rock with large crystals scattered on a background of much smaller crystals called?
A rock with large crystals scattered on a background of much smaller crystals is called a porphyry. This rock texture is the result of two stages of cooling, where large crystals formed during the slower cooling stage, followed by smaller crystals forming during rapid cooling.
A rock with large crystals surrounded by small crystals called?
The rock is called porphyry, which forms when magma slowly cools beneath the Earth's surface. The large crystals are known as phenocrysts, and the smaller surrounding crystals are called groundmass or matrix.
What is the texture called when an igneous rock with large crystals scattered on a background of much smaller crystals?
The texture is called porphyritic. It forms when an igneous rock cools at different rates, resulting in large crystals (phenocrysts) surrounded by a matrix of smaller crystals (groundmass).
What are the large crystals called in an igneous rock mostly composed of a finer grained matrix?
The large crystals are called phenocrysts and the finer grained matrix is known as the groundmass. This texture is known as porphyritic texture, where the rock has two distinct crystal sizes.

Hollow rock with crystals called?
A hollow rock with crystals might be called a geode. A geode is a type of sedimentary rock that has crystals formed inside due to volcanic heating and cooling or by other chemicals seeping into the rock.
What is the texture called when an igneous rock with large crystals scattered on a background of much smaller crystals?
The texture is called porphyritic. It forms when an igneous rock cools at different rates, resulting in large crystals (phenocrysts) surrounded by a matrix of smaller crystals (groundmass).
Rock formations called geodes are filled with layers of crystals. which group of words form the complete predicate?
everything from called to crystals is your predicate.
What are the large crystals called in an igneous rock mostly composed of a finer grained matrix?
The large crystals are called phenocrysts and the finer grained matrix is known as the groundmass. This texture is known as porphyritic texture, where the rock has two distinct crystal sizes.
Rock called geodes are filled with layers of crystals What is the complete predicate?
"are filled with layers of crystals"
A rock with large crystals surrounded by small crystals is called?
a porphyritic rock. This texture indicates that the rock underwent two stages of cooling: slow cooling deep underground (resulting in the large crystals) followed by faster cooling near the surface (resulting in the small crystals).
If there are small crystals in a rock what is it called?
The rock is said to have a fine-grained texture, also referred to as an aphanitic texture.
What is a black intrusive rock with small crystals?
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
If a granite rocks was made of smaller crystals if would be called?
If a granite rock is made of smaller crystals, it would be called fine-grained or fine-grained granite.
