What does an igneous rock's crystal grain size indicate to the observer?
The size of the mineral crystals in an igneous rock is related to the rate of time spent in cooling from magma. Longer exposure to the crystallization temperature means larger crystals. Less time means smaller crystals, or in the case of obsidian, which cools extremely quickly, no crystallization.
What observation about an igneous rock would support the inference that the rock cooled slowly underground?
The rock would have visible mineral crystals--a phaneritic texture.
What is the music as the girls walk into the sports bar in the games people play sex and the city episode?
Garry Glitter- Rock and Roll
What is the affect of temperature on crystal growth?
Temperature doesn't really affect the crystal size; the rate of cooling is the major factor. The faster the mineral, rock, etc. (whatever has the crystals) cools, the smaller the crystals- the slower the larger. If you were "growing" crystals with a set, the warmer the temperature generally means the larger the crystals.
What are large masses of falling rock called?
Large amounts of fallen rock are called "talus."But Rock avalanche is a proper term, as is Rock slide, or rockfall.
What are large crystals known as?
A rock with large crystals indicates that the rock cooled slowly. It is referred to as a phaneritic texture when a rock forms this way.
A rock with large crystals surrounded by small crystals is called?
porphyry
Large size crystals are known as phaneritic what?
A rock with large crystals indicates that the rock cooled slowly. It is referred to as a phaneritic texture when a rock forms this way.
What igneous rock does not have large crystals?
sedimantry
How can you tell if a intrusive rock forms?
Large crystals are diagnostic of an intrusive igneous rock, as large crystals form as the source magma cools slowly.
A rock with large crystals surrounded by small crystals called?
It's an igneous porphyry.
How large crystals form in a metamorphic rock?

What is an extrusive igneous rock with large crystals?
granite
What are two types of igneous rock?
Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.
An igneous rock containing large crystals is most likely a?
intrusive rock
What do the large crystals in this igneous rock tell about the rock?
That it cooled very slowly.
What terms are used to donate the larger crystals in a porphyritic rock?
The large crystals are known as phenocrysts.
