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.
What is the result of cooling and hardening of magma deep underground?
Intrusive igneous rock.
Which type of rock is formed as a result of lava cooling quickly?
extrusive igneous rock
What is the difference between igneous rock that is cools deep within the crust and igneous rock that cools at the surface?
igneous rock that grows at the crust has little to no crystals visible. igneous rock that grows underground has many very large crystals. so the main difference to distinguish the two are the grain sizes. sometimes you can use weight of the rock. mot of the light rocks are rocks formed at the near surface. it may have formed from the result of trapped gases from the volcanic eruption.
Does melted rock that cools quickly result in igneous rock with large mineral crystals?
No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.
What is igneous rock with small crystals called?
The rock is said to be extrusive or possess an aphanitic texture, as a result of relatively rapid cooling.
What does quick cooling of ejected lava result in?
Quick cooling lava will result in extrusive igneous rock, a type of rock classification based on its small crystals being formed from lack of time for growth during solidification.
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.
Does slower cooling result in bigger cystals?
Does slower cooling result in bigger crystals
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.
Igneous rocks form by what?
Igneous rocks are formed as the result of cooling magmas.
What do mudcracks result from?
cooling and igneous rock <3
A fine grained igneous rock forms?
quick cooling
What is the rock formed as a result of cooling magma?
Igneous rock.
What type of rocks form due to cooling?
The earth is composed of various types of rocks, some formed as a result of pressure while others due to cooling. Igneous rocks form when molten lava cools and solidify to form crystals.
What type of igneous rock is a result of lava cooling quickley?
intrusive
How can you tell that gabbro crystalized deeper underground than basalt did?
Gabbro has larger crystals, meaning it had much more time to solidify from magma underground. Larger crystals in igneous rock are an indication of longer cooling times, which result in larger crystal growth.
