Do igneous rocks that form inside the Earth's crust look different from the igneous rocks that form on the Earth's surface?

Yes. Igneous rock that forms on the surface will have small mineral crystals, or in some cases no mineral crystals. Igneous rock that forms below the surface will have larger mineral crystals, from the additional cooling time afforded by the insulating effects of the surrounding Earth material.

Yes, igneous rocks that form inside the Earth's crust typically have a fine-grained texture due to the slower cooling process, while igneous rocks that form on the Earth's surface, such as volcanic rocks, cool more quickly and have a coarser texture. This difference in cooling rates can result in variations in mineral composition and overall appearance between the two types of igneous rocks.

What are extrusive and intrusive igneous rock?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
Where do fine grained igneous rock form?
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
What igneous rock that formed from lava that erupted into earths surface are called?
When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.
Is it true that igneous rocks form only beneath earths surface?
No, igneous rocks can form both beneath and above the Earth's surface. Intrusive igneous rocks form beneath the surface as magma cools and solidifies underground. Extrusive igneous rocks, on the other hand, form on the Earth's surface when lava cools and solidifies quickly.
What is igneas rock origin?
Igneous rocks form from the cooling and solidification of magma or lava. Magma, which is molten rock beneath the Earth's surface, can rise due to pressure and temperature changes, eventually cooling and solidifying to form igneous rocks. These rocks can be classified as intrusive (formed below the surface) or extrusive (formed on the surface).
Where is each type of igneous rock formed?
Intrusive igneous rocks are formed underground from the slow cooling of magma. Extrusive igneous rocks are formed on the Earth's surface from the rapid cooling of lava.
What are extrusive and intrusive igneous rock?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
What refers to rocks that are produced when melted rock or magma from inside Earths cools or hardens on or below Earths surface?
i think the answer your looking for is igneous rock.....that is the type of rock you get after megma cools.....

What is igneas rock?
igneous rocks come from inside the earths crust. Usually through volcanoes, or fissures
How are igeneous rock formed?
Igneous rocks are formed when molten magma from beneath the Earth's surface cools and solidifies. The cooling process can happen either slowly beneath the surface (intrusive igneous rocks) or rapidly on the surface (extrusive igneous rocks), resulting in different textures and mineral compositions.
Are all igneous rocks formed inside the earth?
No, igneous rocks can be formed both inside the Earth (intrusive or plutonic) and on the Earth's surface (extrusive or volcanic). Intrusive rocks form underground when magma cools slowly, while extrusive rocks form on the surface when lava cools rapidly.
What igneous rocks form above the earths surface?
Igneous rocks that form above the Earth's surface are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the surface and cools quickly.
How might gneiss change into an igneous rock?
It would have to be melted into the earths magma and cool down as either intrusive (inside the earth) or extrusive (on the Earth's crust) igneous rock.
