Which crystals most likely formed from molten material that cooled and solidified most rapidly?

If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly

How is Any rock solidified from molten material is classified as?
Any rock created by the cooling of magma or molten material is classified as an igneous rock. These rocks can either be cooled in the earth or on the earths surface. Rocks cooled inside the earth are called intrusive igneous rocks, and have large crystals. Rocks cooled on the earth's surface are called extrusive igneous rocks. These rocks, due to faster cooling times, have very very tiny crystals.
Does rapidly cooled magma or lava contain small crystals?
Yes. Rapid cooling of molten rock produces small crystals.
Why is a volcano an extrusive igneous feature rather than an intrusive feature?
A volcano is composed of material that cooled and solidified at the surface, which makes it extrusive.
Rocks that are melted by heat and then cooled are called what?
Igneous rock is formed from magma or lava that has cooled and solidified.
What rocks are formed from melted rock that has cooled and solidified?
Igneous rock. Hope I helped!
What feature in igneous rocks is the best indication of how rapidly the magma crystallized?
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.

Yes. Rapid cooling of molten rock produces small crystals.
A mineral specimen has very small crystals What is the best explination for how this happened?
The mineral cooled rapidly on earth's surface
How do use the word solidified in a sentence?
wax got solidified as soon as it cooled after melting
Why is a volcano an extrusive igneous feature rather than an intrusive feature?
A volcano is composed of material that cooled and solidified at the surface, which makes it extrusive.
A rock made from cooled magma or lava?
Igneous rock is formed from solidified and cooled magma or lava.
What factor determine the size of crystals in metamorphic rocks?
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
What type of rock had no visible crystals as result of rapid cooling?
Obsidian is an example of a rapidly cooled rock, also known as volcanic glass.
Rocks that are melted by heat and then cooled are called what?
Igneous rock is formed from magma or lava that has cooled and solidified.
A mineral specimen has very small crystals what is the best explanation for how this happened?
It is likely that the mineral formed from molten lava on the Earth's surface. This is because it would have cooled very rapidly, so forming the small crystals.
Why do some igneous rocks have larger crystals but other igneous rocks have crystals so small they have to be seen with a microscope?
Crystal size in igneous rock is dependent on the amount of time spent in cooling from magma or lava. More time means larger crystals. Rocks that have small crystals cooled quickly, so the minerals didn't have time to rearrange and form large crystals before the rock solidified. These small-crystalled rocks are described as aphanitic. Other rocks cooled slowly, so the minerals had time to rearrange and form large crystals before solidifying. These rocks are considered phaneritic. Some rocks cool slowly for a while, and then experience rapid cooling (such as magma that cools slowly inside a volcano, and then cools rapidly when the volcano erupts). Such rocks have large crystals surrounded by tiny crystals. Rocks that form this way are described as porphyritic.
