What is the difference between the two types of igneous rocks?
Extrusive igneous rocks form from magma that erupted onto the surface as lava, where it cooled quickly. On the other hand, intrusive igneous rocks form from magma that cooled slowly, deep underground.Obsidian has tiny crystalsGranite has large crystalsIgneous rocks do not contain any fossils. This is because any fossils in the original rock will have melted when the rock melted to form magma.
The size of the mineral crystals found in an igneous rock is directly related to the?
the rate melted rock cools.
Melted rock that flows to the surface cools quickly forms?
Igneous rocks are formed when molten hot rock flows to the surface of the Earth and rapidly cools down. The crystals that form are rich in silicon and oxygen.
What do extrusive igneous rocks look like?
The particle size (grain size--crystal size) in igneous rock is largely dependent on the amount of time spent cooling and solidifying from molten rock. If cooled quickly, crystals will have little time to grow. Slow cooling allows time for larger crystal growth.
What rock forms when melted rock from inside the earth cools and hardens?
Igneous rock forms when melted rock from inside the Earth cools and hardens. This process can happen either beneath the Earth's surface, forming intrusive igneous rock, or at the surface, forming extrusive igneous rock. Examples include granite, basalt, and obsidian.
What type of igneous rock formed when melted rock reaches earths surface?
When melted rock reaches Earth's surface, it cools quickly and solidifies to form an extrusive igneous rock. This rapid cooling prevents large mineral crystals from forming, resulting in a fine-grained texture. Common examples include basalt and rhyolite.
When melted rock cools it forms?
When melted rock cools, it forms igneous rock. The process of cooling allows the molten rock, also known as magma or lava, to solidify and form crystals. Igneous rocks can have different textures and compositions depending on how quickly or slowly the rock cools.

When melted rock cools above ground it has no or very small what?
Mineral crystals.
What Igneous rocks have large crystals and form when melted rock cools slowly and hardens underneath earth's surface?
They are called intrusive igneous rocks.
When melted rock cools and hardens an intrusive igneous rock is formed?
when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
What is the effect the cause is melted rock cools?
When melted rock cools, it solidifies into igneous rock. This process can result in the formation of crystals within the rock depending on the rate at which it cools. The cooling process can also lead to the creation of different textures and structures in the igneous rock.
In liquid form having been melted by great heat?
A rock having a cavity that is lined with crystals or mineral matter
Is a melted rock a metamorphic rock?
no, if it is melted, it is igneous
Do metamorphic rocks contain layers?
well technically the first diamonds were made from magma before the earth was populated with people, but now the only way to make crystals(not diamonds) is from burning graphite, which is the only other substance completely made from carbon, like diamonds. so yes technically crystals are made from magma when it is spewed up from volcanos.
