Why would lava cool more quickly then magma?
Magma is molten rock that is below ground level so it probably wouldn't be exposed to the open air.
Is cool magma sinking and warm magma convection?
When cool magma sinks and warm magma rises, yes that is convection.
Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
Why would lava cool more quickly then lava?
Magma is molten rock that is below ground level so it probably wouldn't be exposed to the open air.
Do intrusive igneous rocks form quickly or slowly?
Fast and slow are relative terms. If a heated igneous rock takes 3 hours to cool, is that fast or slow? During their formation, however, magma can solidify very slowly or very quickly. Rocks that have cooled quickly from magma are referred to as extrusive igneous rocks, such as obsidian and scoria. Rocks that have formed from slow cooling magma are called intrusive igneous rocks, such as granite and gabbro. The difference between the two types is in their grain size. Slow cooling magma produces large grained rock, and fast cooling magma produces fine-grained rock.
What is the term when magma cool slowly then cools quickly?
I cant tell!
What are Igneous rocks that cool quickly beneath Earth's crust called?
Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.
What is the origin of obsiadan?
If you are asking about how they were formed magma from volcano that are shot in the air of quickly spewed out causing the magma to cool very quickly forming a very smooth surface on obsidian. Becuase the magma cooled so fast it couldn't slowly cool into a rough textured rock.
Does andesite cool quickly or slowly?
Lava will cool quickly compared to underground magma.
Does magma creates intrusive rock cool down quickly slowly?
Yes, magma intrusions stays inside the earth. and this goes relatives slowly.
Why would lava cool more quickly then magma?
Magma is molten rock that is below ground level so it probably wouldn't be exposed to the open air.
How do fine grain igneous rock form?
Fine-grained igneous rocks form when the magma cools quickly.
Is cool magma sinking and warm magma convection?
When cool magma sinks and warm magma rises, yes that is convection.
Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
As compared to mafic igneous rocks do all felsic igneous rocks cool and solidify more slowly?
No. Whether igneous rocks cool quickly or slowly is more dependent on whether the rock is intrusive or extrusive than whether it is mafic or felsic. Because it is so viscous it is often difficult for felsic magma to erupt, and so it is more likely to be intrusive and thus cool slowly. When felsic magma is involved in an eruption, it often erupts explosively. Some of the molten rock ejected cools extremely rapidly, forming volcanic glass.
How obsidian rocks form?
They are formed when either a sedimentary rock or a metamorphic rock are exposed to high heat and turn into magma and then cool quickly.
Why would lava cool more quickly then lava?
Magma is molten rock that is below ground level so it probably wouldn't be exposed to the open air.
