What is the difference between exrusive an intrsive igneous rock?
Extrusive igneous rocks are formed from lava that cools quickly on the Earth's surface, resulting in fine-grained textures. Intrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface, resulting in coarse-grained textures.
Igneous rock that cools very quickly when it forms may have a texture that is what?
A texture characterized by tiny mineral grains or a glassy appearance.
What is the difference between a vesicular igneous rock and a nonvesicular igneous rock?
Vesicular rocks contain lots of small cavities, usually filled with air. Non- vesicular ones don't have these holes. Vesicles are formed when magma suddenly rushes out on to the surface and its dissolved gases come out of solution, blowing bubbles in the liquid rock which are preserved as it cools quickly and sets. An example of a vesicular rock is pumice.
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.
How can you tell the difference between an igneous rock that formed above ground and one that formed below?
Igneous rocks that form below ground (intrusive) have larger crystals due to slower cooling, whereas igneous rocks that form above ground (extrusive) have smaller crystals or a glassy texture due to rapid cooling. Additionally, intrusive rocks may show visible layering or bands, while extrusive rocks typically have a more uniform appearance.
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

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.
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 is an example of a magic igneous rock?
Obsidian is a type of magic igneous rock known for its dark color and shiny appearance. It is created when lava cools quickly, and it is often used in rituals or for scrying due to its believed mystical properties.
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
If lava cools to quickly that ions don't have time to arrange themselves into crystals will form what?
glassy texture, hope this helps :)
What kind of rock can form very quickly?
igneous
