Extrusive igneous rock forms when lava cools quickly on the Earth's surface. This rapid cooling prevents large crystals from forming, resulting in a finer-grained texture. In contrast, intrusive igneous rock forms when magma cools slowly beneath the surface, allowing for the development of larger crystals.
What else can I help you with?
Intrusive igneous rock is cooled and solidified above ground?
False. Intrusive igneous rock forms underground when magma cools and solidifies slowly. Extrusive igneous rock forms when magma erupts onto the Earth's surface and cools quickly.
What type of rock can be intrusive and extrusive?
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
What are the ways igneous rock can form?
intrusive igneous rock: magma cools and hardens in the earth and later forms an intrusive igneous rock. extrusive igneous rock: magma flows onto earth's surface and becomes lava. Then, lava cools and hardens above earth's surface and later forms an extrusive igneous rock.
Write the difference between extrusive and intrusive igneous rocks?
igneous Extrusive is cool on the outside of the crust and cools quickly before crystal forms igneous Intrusive is cool on the inside of the crust and cools slowly and allowing crystal to form
What groups of rocks can igneous rocks be formed from?
igneous rocks are formed by magma reaching earths surface and cooling quickly to form extrusive igneous rock.another igneous rock is called intrusive igneous rock. it is formed when magma cools and hardens below the surface.
Is feldspar extrusive or intrusive?
Feldspar can be found in both extrusive and intrusive igneous rocks. In extrusive rocks, feldspar forms when magma cools and solidifies quickly on the Earth's surface. In intrusive rocks, feldspar forms as magma cools and solidifies slowly beneath the Earth's surface.
Is gabbro an intrusive or extrusive?
Intrusive Igneous Rock , it is because gabbro has a very rough texture.Intrusive cools slowly and extrusive cools rapidly.
Intrusive igneous rock is cooled and solidified above ground?
False. Intrusive igneous rock forms underground when magma cools and solidifies slowly. Extrusive igneous rock forms when magma erupts onto the Earth's surface and cools quickly.
Is volcanic glass an intrusive or extrusive igneous rock?
Volcanic glass is an extrusive igneous rock. It forms when molten lava cools quickly on the Earth's surface, preventing the formation of crystals.
What type of rock can be intrusive and extrusive?
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
What igneous rocks are both intrusive and extrusive?
The igneous rocks that can be both intrusive and extrusive are known as porphyritic rocks. These rocks form when magma partially cools underground (intrusive) before being erupted onto the Earth's surface where the remaining magma cools quickly (extrusive). This dual cooling process creates distinctive textures in the rock, with larger crystals (phenocrysts) embedded in a finer-grained matrix.
What does extrusive rock means?
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
What are the ways igneous rock can form?
intrusive igneous rock: magma cools and hardens in the earth and later forms an intrusive igneous rock. extrusive igneous rock: magma flows onto earth's surface and becomes lava. Then, lava cools and hardens above earth's surface and later forms an extrusive igneous rock.

What is the difference between igneous rock that cools above and igneous rock that cools below ground?
That depends on where it cools. Igneous rock forms from magma or lava (there's a difference!) cools and hardens. Extrusive igneous rock forms above the earth's crust, like when the lava from a volcanic eruption hardens. Intrusive igneous rock cools inside the earth when conditions change and the area around the magma cools allowing the magma to cool.
What are extrusive and intrusive igneous rock?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
