Rocks with visible crystals display what is known as a phaneritic 'blank'?
The display a phaneritic texture.
What igneous rock has no visible crystals as a result of rapid cooling?
Obsidian rocks are cooled very fast, and you cannot see the crystals in them.
Plutonic rocks are characterized by which type of texture?
Plutonic rocks have a phaneritic texture. It is characterized by interlocking crystals of several minerals that are easily visible and randomly distributed. .
Does slow cooling of molten rock lead to formations of large crystals?
Slow cooling of molten rock leads to rocks with an phaneritic texture; one with larger, visible mineral crystals.
Rocks that contain crystals exhibit what texture?
What rocks contain crystals?
What is a type of igneous rock that forms visible crystals?
Granite, gabbro, and diorite are a few igneous rocks that forms crystals. Igneous rocks that form visible crystals are intrusive igneous rocks, rocks that form under the earth's surface.
Do phaneritic igneous rocks contain viewable crystals?
By definition, yes. In contrast, aphanitic rocks do not have visible 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.
Rocks with visible crystals display what is known as a phaneritic 'blank'?
The display a phaneritic texture.
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 are rocks called that are formed by magma which has cooled below the surface of the earth?
They are called intrusive igneous rocks, characterized by their visible mineral crystals.
How is Any rock solidified from molten material is classified as?
Any rock created by the cooling of magma or molten material is classified as an igneous rock. These rocks can either be cooled in the earth or on the earths surface. Rocks cooled inside the earth are called intrusive igneous rocks, and have large crystals. Rocks cooled on the earth's surface are called extrusive igneous rocks. These rocks, due to faster cooling times, have very very tiny crystals.
What igneous rock has no visible crystals as a result of rapid cooling?
Obsidian rocks are cooled very fast, and you cannot see the crystals in them.

Rocks that contain crystals exhibit what texture?
What rocks contain crystals?
Do rocks have crystals?
Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.
