What is the cooling rate of a coarse grained igneous rock?
Coarse grained igneous rock is formed from the slow cooling of magma.
What factors can affect the texture of an igneous rock?
The length of time the magma had to cool
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.
What controls the grain size of igneous rock?
The rate at which the igneous rock cools controls grain size. Slower cooling results in larger crystals while faster cooling results in smaller crystals.
. As the rate of cooling of igneous rocks increases the size of the crystals that form?
The size of crystals decreases as the cooling increases. This is called an inverse relationship.
What is the cooling rate of a coarse grained igneous rock?
Coarse grained igneous rock is formed from the slow cooling of magma.
Is igneous rock that formed from cooling lava fined-grained?
yes because of the fast cooling rate
What are two factors affect the type of igneous rock that is formed?
The mineral composition of the magma and the rate at which it cools determines what rock forms.
What factors can affect the texture of an igneous rock?
The length of time the magma had to cool
Which igneous rocks are fine grained to due to fast cooling?
Extrusive igneous rocks are fine grained due to fast cooling. They cool at a faster rate than most igneous rocks.
What are igneous features caused by magma?
The features for igneous rock caused by magma is that1. Formed beneath the surface2. The rate of cooling is slow3. The crystal sizes are large4. The texture is roughThis rock is also known as an intrusive rock because it formed inside the earth.
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.
What can determine the size of grains in igneous rocks?
Cooling rate of molten rock
What determines the mineral grain size in an igneous rock?
The cooling rate of the rock.
What rate of cooling produces the largest crystals in igneous rocks?
A slow rate of cooling. The slower a magma cools, the longer the crystals have to grow, thus the bigger they will be.
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 determines the size of grains in igneous rocks?
The cooling rate of molten rock
