Which would have larger crystals an igneous rock formed from magma below the surface or igneous rock cooled from lava on the surface?
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
How is igaeous rock formed?
Igneous rock is formed when magma cools and solidifies either below the Earth's surface (intrusive) or at the surface (extrusive). The rate of cooling determines the size of mineral crystals in the rock. Intrusive rocks have larger crystals due to slower cooling, while extrusive rocks have smaller crystals due to rapid cooling.
What determines whether igneous rock is intrusive or extrusive A. the density of the rock B. the chemical composition of the rock C. where crystals in the rock are found D. where the rock was formed?
D. where the rock was formed determines whether igneous rock is intrusive or extrusive. Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, allowing larger crystals to develop. In contrast, extrusive igneous rocks form from lava that cools quickly on the surface, resulting in smaller crystals. Thus, the location of formation is key to classifying igneous rocks.
An igneous rock with large crystals formed where?
An igneous rock with large crystals typically formed deep within the Earth's crust, where magma cools slowly over time. This slow cooling allows crystals to grow larger, resulting in a coarse-grained texture. Such rocks are known as intrusive or plutonic igneous rocks, with granite being a common example. In contrast, rapid cooling at the Earth's surface produces finer-grained rocks with smaller crystals.
How did igneous rocks form?
Igneous rocks form when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface after a volcanic eruption (extrusive igneous rocks). This cooling process can occur slowly, resulting in larger crystals (coarse-grained rocks), or quickly, which produces smaller crystals or glassy textures (fine-grained rocks).

If Smaller crystals in igneous rock form when?
Smaller crystals form in igneous rocks if they are extrusive, meaning they formed at or near the Earth's surface. Because of the quick cooling of the magma/lava, there is no time for the crystal structure to expand, leaving it smaller than if it was an intrusive rock (forming inside the Earth, below the surface).
What is different from crystals underground than above?
Underground crystals are bigger where as crystals formed on the surface are smaller.
What are Igneous rocks that have large crystals and small crystals?
Igneous rocks with large crystals are called intrusive rocks, formed from magma cooling slowly beneath the Earth's surface, allowing for large crystals to form. Igneous rocks with small crystals are called extrusive rocks, formed from lava cooling quickly on the Earth's surface, resulting in small crystals due to rapid cooling.
What would have larger crystals igneous rock that formed below earths surface or above?

Where does Igneous rock form below or above?
Igneous rocks are formed from the cooling of lava/magma. (Lava is magma that has been moved from beneath the Earth's surface to above.) They can be formed above or below the Earth's surface- when formed above is called 'Extrusive Igneous rock' and when formed below is 'Intrusive Igneous rock'. When a rock is extrusive, it forms small crystals. When it is intrusive, it causes large crystals to form.
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.
Why would granite have larger crystals than igneous rocks formed from lava cooled above earths surface?
I think igneous rock have a larger crystal than all the others because igneous rock is all the way at the bottom of earth surface and it keeps cool of or hot at the same time.
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.
How is the formation of intrusive igneous rock different from that of extrusive igneous rock?
Intrusive igneous rocks is formed from magma that cools, solidifies, crystallizes, and hardens slowly within the earth's crust, and this makes its crystals large. In the case of the extrusive igneous rocks, they develop from the rapid cooling, solidification, crystallization and hardening of lava on the earth's surface and this makes them more smooth and having minerals with crystals of smaller size.
