What is similar between magma and lava?
They're are both molten rock, also contain suspended crystals, dissolved gas.
What is pegmatite texture?
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
Did gabbro cool fast or slowly?
Gabbro cooled slowly underground, resulting in the formation of coarse-grained crystals in the rock. This slow cooling process allows large crystals to grow and develop in the molten rock.
Which type of rock contains minerals arranged in crystals and forms when molten rock cools and turns solid?
Igneous rock contains minerals arranged in crystals and forms when molten rock cools and solidifies. Examples include granite and basalt.
Why don't crystals always form in extrusive rock?
In many cases the molten rock at the surface cools too quickly for crystals to form.
How does crystallization form?
crystals form from molten rock as the molten rock cools. if the molten rock cools very fast then you may have small crystals growing or no crystals at all. if the molten rockk colls slowly then you then you have large crystals growing. this happens when the molten material is deep in the earth. examples of these types of crystals are Rubies, Emeralds, and Diamonds. crystals may also form when water is evaporated. salt crystals are an example as they form when salt water evaporates.
Does slow cooling of molten rock lead to formations of large crystals?
Yes, slow cooling of molten rock typically leads to the formation of large crystals. This is because slower cooling allows more time for the atoms in the molten rock to arrange themselves into a more ordered and stable crystal lattice structure. The slower the cooling process, the larger the crystals that can form.
Why do plutonic rock and volcanic rock have big and small crystals respectively?
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
Rocks that contain crystals exhibit what texture?
Rocks that contain crystals exhibit a coarse texture. The crystals within the rock are generally large enough to be seen with the naked eye, giving the rock a grainy appearance.
What is similar between magma and lava?
They're are both molten rock, also contain suspended crystals, dissolved gas.
What kind of igneous rock usually contain large crystals?
Intrusive or granite.
How do small crystals form?
Answer: Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth. Examples of these types of crystals are diamonds, emeralds, rubies, etc.
What type of crystal grain is formed when molten rock cools slowly?
Large crystals with a coarse crystal grain texture.
What is pegmatite texture?
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
Did gabbro cool fast or slowly?
Gabbro cooled slowly underground, resulting in the formation of coarse-grained crystals in the rock. This slow cooling process allows large crystals to grow and develop in the molten rock.
How do new mineral grow within existing rocks?
Crystals usually form from molten rock as the molten rock gradually cools.
What type of crystals form when molten rock cools quickly?
it forms ingenous rock ...
