What else can I help you with?
Which kind of of igneous has more crystals extrusive or intrusive?
instrusive Rock
What is an igneous rock with small crystals?
If you're not looking for anything specific, any extrusive igneous rock will have smaller crystals, if any at all. This is because they cool quickly on the surface, leaving little time for crystals to form/grow.
What igneous rock has crystals that are not visible?
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
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.
Extrusive igneous rock are made from?
Extrusive igneous rocks are formed from lava that cools and solidifies quickly on the Earth's surface. This rapid cooling results in small mineral crystals or a glassy texture in the rock. Examples of extrusive igneous rocks include basalt, andesite, and rhyolite.
What is a black intrusive rock with small crystals?
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
What is an extrusive igneous rock with large crystals?
granite
How can you determine if an igneous rock has had an intrusive or extrusive organ?
by the size of the crystals, big crystals intrusive, small crystals extrusive
What is a identifying characteristic of extrusive igneous rock?
small crystals
How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.

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 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.
When a igneous rock with large cystals cools what is it?
An intrusive igneous rock has larger crystals than an extrusive igneous rock because it has had a longer period of time to solidify underground.
Where would you expect to find an igneous rock with small crystals?
You would expect to find an igneous rock with small crystals near the Earth's surface where the rock cools relatively quickly, such as in volcanic eruptions or magma intrusions that do not have much time to grow large crystals. These rocks are known as volcanic or extrusive igneous rocks.
