What do small crystals in an igneous rock mean?
The size of the crystals in an igneous rock tells us how fast the magma cooled.
Why do some igneous rocks have big crystals or grains and some igneous rocks have small crystals or grains?
how long they stayed in the volcano; how much time the crystals had to form
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 factor determines if an igneous rock has no crystals small crystals or large crystals?
it depends on the heat, if it cool very quick then it has small crystals but if it cool very slowly than it is bigger the slower the cooling period the bigger the crystals
What type of rock is gravel?
Gravel is a physical label for small rock fragments. Gravel can be produced by crushing of any rock type, i.e., metamorphic, sedimentary, or igneous, or can be obtained from vast deposits left by glacial means, which normally require a mechanical sorting for required sizes. Naturally pre-sorted deposits can be found in rivers and stream beds.
Do igneous rocks have small crystals large crystals or no crystals?
It depends on the type of igneous rock. Intrusive igneous rocks such as granite have large crystals, extrusive igneous rocks may have small crystals as in basalt or no crystals as in pumice.
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.
Where would you expect to find an igneous rock with small crystals?
you would find igneous rocks with small crystals at the bottom of the volcano, this is because when the rocks crack. It brakes apart into igneous rocks

What are Igneous rocks that have large crystals and small crystals?
Such rocks are called porphyritic.
A rock with large crystals surrounded by small crystals called?
It's an igneous porphyry.

Why do andesite have small crystals?
Andesite is an Igneous Rock. It has small crystals because it cooled quickly d;D

What is a identifying characteristic of extrusive igneous rock?
small crystals
What size are the crystals in an igneous rock that cools quickly?
Small

by the size of the crystals, big crystals intrusive, small crystals extrusive
