Describe and explain the difference in the crystalline texture of volcanic rock and rock formed from an intrusion?
The texture of intrusive igneous rocks is phaneritic, which is characterized by coarse-grained large crystals that are visible to the naked eye. The texture of volcanic rocks, meanwhile, is porphyritic, which is characterized by fine-grained crystals.
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
What is the difference between fine and coarse grained igneous rock?
Coarse grained textured rocks (phaneritic) have very large crystals because the magma, from which they are created, cools very slowly. Fine grained rocks (aphaneritic) have small crystals because the lava, from which they are created, cools down very quickly.
When large masses of magma solidify far below earths's surface they form igneous rocks that have a?
Coarse-grained texture
Why are raindrop impressions are preserved in in fine grained sedimentary rock rather than a coarse grained?
because raindrops have small particles and coarse grained sedimentary rocks have big particles so it is easier for raindrop impressions to occur in fine grained sedimentary rocks
What type of texture do extrusive rock such as basalt have?
Small grained texture from small crystal size.
What is the texture of igneous rocks that form far below earths surface?
Course grained texture.
What is the relationship between an igneous rocks texture and where it formed?
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.

What is the term given to igneous rocks with crystals too small to see without a hand lens?
These are extrusive igneous rocks with an aphanitic texture.
What is the texture of the very finest grained rocks called?
vitreous or glassy (obsidian)

Which weather faster small rocks or large rocks why?
fine grained rock will weaher faster thatn the course grained rock
If there are small crystals in a rock what is it called?
The rock is said to have a fine-grained texture, also referred to as an aphanitic texture.
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
