What are large mineral crystals commonly found in?
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
What kind of rock us formed from lava that cools on earth surface?
This would be an extrusive igneous rock, which will have a smooth appearance because the mineral crystals are too small to see. If the lava is basic you will probably get basalt, and if it's acidic it's likely to form rhyolite.
Would quartz or plagioclase be more likely to form a well shaped crystal in an igneous rock?
A well-shaped crystal in an igneous rock needs room and time to grow. So, minerals with high melting points form well shaped crystals while ones with lower melting points don't because there isn't as much time for them to form. Quartz crystallizes at a lower temperature than plagioclase so plagioclase is more likely to form well-shaped crystals.
What type of solution is most likely to form crystals as it cools?
A supersaturated solution is most likely to form crystals as it cools.
Where is an igneous rock most likely from?
igneous rocks usally form by cooled magma.
What are large mineral crystals commonly found in?

An igneous rock containing large crystals is most likely a?
intrusive rock
Is rock with visible layers and no visible mineral crystals likely to be formed from lava hardening on Earth's surface?
Probably not. While layered lava flows are not uncommon, most layered rocks formed from the accumulation and lithification of sediment.
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.
What does the presence of large crystals in an igneous rock indicate?
It indictes slow rate of cooling, solidification, and crystalization, as a result of depth of the magma. This implies that the rock is most likely to be an intrusive igneous rock.

Lin found an igneous rock with large grains of mineral crystal where did this rock most likely form?
d. on the surface of the Earth
Do you think extrusive or intrusive igneous rocks are likely to have larger crystals?
If a rock has large crystals, it is an intrusive rock. Intrusive rocks form underneath the Earth's surface. Magma cools slowly so it has time to form large crystals. An example is granite, where you can see the crystals with your naked eye. Rocks that have small crystals are extrusive rocks. Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form. An example is obsidian, where you cannot visibly see the small crystals; it just looks like one black, glassy rock.
When Magma is launched from a volcano forms what type of rock?
A volcano is made of extrusive igneous rock. The specific type of igneous rock will vary from one volcano to another.
A mineral specimen very lage crystals where did it most likely form?
Under ground took a lone time to cool all I can tell you
What kind of rock is calcite igneous metamorphic or sedimentary?
ANSWERCalcite is really not a rock it is a mineral therefore it can not really be metamorphic , sedimentary , or igneous. But it is usually associated in materials of sediment so most likely it is sedimentary. If you would have to pick one. SEDIMENTARY
What is the magma that reaches the earth's surface?
Magma that reaches the surface is referred to as lava.magma that has reached the earth's surface tends to cool faster, that is why the rock will have more holes in it than a rock that has not reached the earth's surface. magma that has cooled enough to become a rock is known as a igneous rock. but there are two types of igneous rock. ther is intrusive igneous and extrusive igneous. intrusive is when the magma has cooled on the inside. this rock will have large crystals because it has cooled slower and most likely it will have a fine grained texture. extrusive igneous is when magma has reached earths surface (thats when it becomes lava) and has cooled. these rock with either have very small microscopic crystals or no crystals at all because the lava cools so quickly that they do not have enough time to really form.
