It depends how slow/fast it cools into a rock. The slower it cools, the larger the crystals. The faster it cools, the smaller the crystals. It can also have no crystals. Let's say lava shot itself into the water. It cools so fast it might not have crystals

What is one similarity between Granite and Rhyolite?
Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. They have essentially the same composition. The difference between them is that granite cools slowly underground, forming large crystals while rhyolite cools rapidly above ground after a volcanic eruption forming small crystals or no crystals.
Do large grain rocks form from lava or magma?
they form from both...ithink
Where can you find crystal?
You can find crystals, meaning rocks and minerals in their natural crystal form (they grow that way), almost anywhere in nature - both on the ground and under the ground. Most crystals are mined, since many have formed millions of years ago. Check out rockhounding sites if you want to mine your own, but the easiest way to find crystals is to go to a rock shop or metaphysical store in your area. You can find them on line, but it is not the same as actually touching them in order to get to know what you are looking at. See also the link below.
What conditions determine whether metamorphic changes willl occur over a large or small area?
Change over large areas - usually the deeper down rocks are the more change occurs.Usually due to both heat and pressure.Mountain Ranges are example of large area metamorphic. Change over small areas - formed by heat pressure ALONE
How are magma rocks and lava rocks alike?
they are the same except magma has never been exposed
What is both small and large?
Jumbo rhumpi
How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
How are igneous and metamorphic rocks alike?
Both were created under extreme heat and can contain crystals or gems.
What is an igneous rock with both large and small crystals?
The type of igneous rock that has large crystals surrounded by smaller crystals is not a rock but a porphyritic texture. This texture describes igneous rock that has porphyrites, or large crystals, with surrounding tiny particles, or groundmass.
Which term best describe the process of weathering and erosion?
1. Breaking of large rocks into small pebbles 2. Dissolving of limestones to form a cave 3. Movements of rocks and pebbles due to the flow of water.
Where is pigeonite normally found?
Pigeonite is normally found in igneous rocks such as dacite and andesite which are both extrusive igneous rocks. Pigeonite is found in meteorites such as eucrite and achondrite. In volcanic rocks it is found as phenocrysts and as crystals in meteorites.
Is an emerald large or small?
It can be both! :)
What material is added to ice cream to prevent large crystals of ice during the freezing process?
Cream and egg yolks both help prevent large crystals of ice and render ice-cream makers unnecessary.
Do all rocks have crystals in it?
Most rocks do but there are some exceptions. Coal (such as bituminous coal) is composed of organic material but is considered a sedimentary rock. Glassy rocks such as obsidian or pumice cool too quickly to contain crystals.

Are crystals stones?
No, but stones and crystals are both minerals.
