What is the difference in appearance between igneous rocks that have cooled slowly and igneous rocks that have cooled quickly?

Igneous rocks that cooled slowly are intrusive. Igneous rocks that cooled quickly are extrusive. Intrusive rocks form larger crystals, because the crystals have a longer time to grow. Extrusive rocks have small to no crystals, because they had little or no time to grow/form.

How can you tell the difference between an igneous rock that formed above ground and one that formed below?
Usually, the determining factor is the size of the mineral crystals in the rock. Igneous rocks that have solidified above ground cool quickly and have less time for larger crystals to grow.
What type of texture forms from igneous rock cooling very quickly?
When lava cools quickly, the minerals in it form very tiny crystals which can usually only be seen under a microscope. To the eye, this results in a smooth appearance.
What is the difference between an igneous rock with a glassy texture and one with a fine texture?
The main difference is that the glassy textured igneous rock cooled from lava with extreme quickness, while the one with a fine texture cooled less quickly. Obsidian is a natural glass, created by rapidly cooling lava, where mineral crystals do not have enough time to form before the lava solidifies.
What is the igneous rock that cooled too quickly for a crystal structure to form?
Volcanic glass or obsidian is a quickly cooled igneous rock without a mineral crystal structure.
What is the difference between the two types of igneous rocks?
Extrusive igneous rocks form from magma that erupted onto the surface as lava, where it cooled quickly. On the other hand, intrusive igneous rocks form from magma that cooled slowly, deep underground.Obsidian has tiny crystalsGranite has large crystalsIgneous rocks do not contain any fossils. This is because any fossils in the original rock will have melted when the rock melted to form magma.
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 is the difference between igneous rock that is cools deep within the crust and igneous rpck that cools at the surface?
igneous rocks that cools deep inside the earth are well settled while those at surface are not as lava that spreads on surface gets solidified quickly and dont get time to settle

If lava cools to quickly that ions don't have time to arrange themselves into crystals will form what?
glassy texture, hope this helps :)

Why Is the crystal in igneous rock small if it cools quickly from magma?
The crystals within don't have as much time to grow when igneous rock is cooled more quickly as in extrusive igneous formation.
What kind of rock can form very quickly?
igneous
What is it called when igneous rocks cool quickly?
obsidian

What are Igneous rocks that cool quickly beneath Earth's crust called?
Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.
