Does intrusive rock cool fast or slow from magma?
Intrusive rock cools slowly from magma underground, allowing large mineral crystals to form. This slow cooling process is why intrusive rocks, such as granite and diorite, have a coarse-grained texture.
Do intrusive igneous rocks form quickly or slowly?
Fast and slow are relative terms. If a heated igneous rock takes 3 hours to cool, is that fast or slow? During their formation, however, magma can solidify very slowly or very quickly. Rocks that have cooled quickly from magma are referred to as extrusive igneous rocks, such as obsidian and scoria. Rocks that have formed from slow cooling magma are called intrusive igneous rocks, such as granite and gabbro. The difference between the two types is in their grain size. Slow cooling magma produces large grained rock, and fast cooling magma produces fine-grained rock.
Does gabbro cool fast or slow?
Gabbro typically cools slowly beneath the Earth's surface, allowing large mineral crystals to form. This slow cooling process results in a coarse-grained texture in gabbro rocks.
How can you tell if a rock cooled fast or slow?
You would examine a fracture surface of the rock. Intrusive igneous rocks that have cooled very slowly underground have visible crystals and are said to have a phaneritic texture. Granite is an example of this type of rock. Extrusive igneous rocks that have cooled quickly from lava above or on the surface generally will have crystals too small to be visible with the naked eye, in a texture that is referred to as aphanitic. Obsidian is an example of this type of rock.
What size crystal do magma make?
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
Does anorthosite cool fast or slow?
Slowly

How fast if travel 1mile in 2hours?
Very Slow 804 meters/hour. Is It snake crawling on marble road.
What is an example of a change that is slow and periodic fast and non periodic fast and periodic slow and non periodic?
What is your definition of slow? Minutes, years, eons? Some that might do: slow and periodic: the progression of the seasons fast and non-periodic: an explosion fast and periodic: the swing of a pendulum slow and non-periodic: the weathering of rocks.
Is cars cool?
if a fast and expecive car yes.But a slow and ugly car no.
Is weathering of rocks fast or slow process?
Weathering of rocks is generally a slow process that can take years to centuries. However, the rate of weathering can be influenced by factors such as climate, rock type, and presence of vegetation, which can either accelerate or slow down the process.
How does the crystal sizes of igneous rocks indicate the rate of cooling and whether the rock is extrusive or intrusive?
Generally, large crystals represent slow cooling rates and small crystals represent fast cooling rates. Crystals need time to form and since extrusive rocks cool very quickly, they have very tiny crystals and some don't even have crystals because the rate of cooling was so fast that crystals didn't have time to nucleate. On the other hand, intrusive rocks cool rather slowly allowing crystals to grow.
Why does cool water move slow?
Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.
What is the main factor that affects the size of minerals in igneous rocks?
Crystal size is largely dependent on the time the magma takes to cool and solidify. Slow cooling equals large crystals. Fast cooling equals small crystals.
Fast and slow weathering?
Fast weathering processes include physical weathering from frost action and chemical weathering from acid rain, leading to the quick breakdown of rocks. Slow weathering processes involve gradual decomposition of rocks over time due to factors like temperature changes and slight chemical reactions, resulting in erosion and soil formation.
