What determines how large the crystals in an igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
What determines how large the crystals in the igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
Does magma beneath the surface cool fast?
Magma cools down about a week or so it is extremely hot about 350 degrees Fahrenheit , when it cools down it turns into crystals which are inorganic, naturally, solid, and having a atom arrangement.
Why do obisidian rocks have no crystals?
because the magma cooled so fast the little pieces of cooled magma bonded already so there is not enough space for the little pieces to grow into crystals. Similar to concrete the bricks are the pieces of already cooled magma. But then the concrete is immediately poured onto the brick t=and cooled in 1 second and hardened. That does not allow space for the bricks to grow as everything is bonded and no more magma is left to add to the pieces to make them bigger.
Volcanic glass forms when magma cools very quickly?
Yes obsidian is glassy because it cooled very fast.
What do small crystals in an igneous rock mean?
The size of the crystals in an igneous rock tells us how fast the magma cooled.
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
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.
When magma cools too fast what happens to the size of the crystals?
When magma cools fast, crystals are small.Less time to form crsytalsWhen magma cools slow, crystals are large.More time to form crystalsWhen magma cools very fast, crystals do not form; nothing.Very less time to formWhen magma cools very slow, large crystals form; a LOT.A lot more time to form
Where in the world is pumice found?
Pumice is formed from magma coming out of volcanoes where rhyolite would have formed, (Destructive plate margin), but has cooled so fast that it appears glassy, and almost non-crystalline.
What is the Grain pattern of conglomerate?
Sedimentary rock usually exhibits stratification, or layering of sediments.
How fast does the magma from an erupted volcano go?
it go pretty fast
