The rate of cooling is the speed at which magma or lava crystallizes. When the speed is slow it results in big crystals. When the speed is fast it results in small crystals.

What factors can effect the texture of a igneous rock?
The texture is determined by the rate it takes the molten to cool to form the rock.
How are crystallization and cooling magma related?
Crystallization and cooling magma are related in the sense that cooling and crystallization occurs simultaneously. As the magma cools it crystallizes, the faster the rate of cooling the quicker crystals would develop and the slower the cooling the larger the crystals in other cases when the magma cool so rapidly crystal development may not be so prominent.
What effect does a fast cooling rate have on grain size in igenous rocks?
Fast cooling lava or magma creates an aphanitic or small crystal (grain) textured igneous rock.
What is the cooling rate of a coarse grained igneous rock?
Coarse grained igneous rock is formed from the slow cooling of magma.
How does the rate of cooling affect the type of igneous rock formed?
The rate at which the rock cool from the liquid magma determines their texture
What determines the type of mineral formed by cooling magma?
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
What is the Crystal size of lava?
When the magma reaches the surface, it is called lava. The rate at which the magma cools determines the kind of igneous rocks that are formed. Faster cooling surface lava creates rock that is fine grained or aphanitic. The rapid cooling doesn't allow large crystals to form. The slower cooling that takes place underground allows larger crystal formation. Granite is an example of this type of rock formation.
What king of rock does lava form?
usually it depends on the rate of cooling of the lava....
What affects the grain size of igneous rock?
Porphyritic texture indicates that a magma has gone through a two stage cooling process. The magma has cooled sufficiently underground to allow some minerals to crystallize and grow in size; the magma is then expelled above ground where the remaining liquid magma solidifies quickly, allowing only small crystals to develop.
Is igneous rock that formed from cooling lava fined-grained?
yes because of the fast cooling rate
What factors can effect the texture of a igneous rock?

How are crystallization and cooling magma related?
Crystallization and cooling magma are related in the sense that cooling and crystallization occurs simultaneously. As the magma cools it crystallizes, the faster the rate of cooling the quicker crystals would develop and the slower the cooling the larger the crystals in other cases when the magma cool so rapidly crystal development may not be so prominent.
What are the two major factors that influence the creation of an igneous rock?
Rate of cooling of the magma and Chemical composition of the magma.
What effect does a fast cooling rate have on grain size in igenous rocks?
Fast cooling lava or magma creates an aphanitic or small crystal (grain) textured igneous rock.
How is the texture of an igneous rock related to the rate which it cooled?
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
What makes a igneous rock an igneous rock?
An igneous rock is formed through the solidification of molten material, either magma or lava, that cools and crystallizes. This process occurs below or on the Earth's surface. The mineral composition and texture of igneous rocks vary depending on factors such as the cooling rate and the composition of the molten material.
What affects the type of igneous rock that is formed?
Mineral composition of the magma, Rate of cooling of the magma, Temperature of the magma, Presence of volatiles and Amount of water present in the magma.
