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

Where would you expect to find the largest crystals in a lava flow?
You would find the largest crystals in a lava flow in the center of the flow. The largest forms of igneous intrusions are called batholiths.
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.
What is the size of a crystal in an extrusive igneous rock?
Normally the crystals in extrusive igneous rock are small enough as to not be visible without magnification. The exception would be a porphyritic rock that has visible crystals dispersed in a fine-grained matrix. This type of rock represents a partial cooling of magma before expulsion by volcanism.
How would you know the difference between igneous and sedimentary and metamorphic rock?
Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.
What igneous rock has no visible crystals?
Granite is a coarse grained igneous rock without Pyroxene.
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 cooled the most rapidly?
Igneous rocks with very small or no visible crystals are formed by rapid cooling. A good example would be obsidian (which is a volcanic glass) and BAsalt which may have an aphanitic texture (crystals to small to see with the naked eye).
What is the name of A dark rock with small crystals formed on the surface of the earth?
Most generally, an igneous rock with small crystals formed from the cooling of lava on the surface of the Earth would be classified as basalt.

What type of rocks would you expect to find around a volcano crater?
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
What would have larger crystals igneous rock that formed below earths surface or above?
below
what rock would take longer to form and the slower it forms the larger it's crystals will be?
I think it would be igneous
Which would have larger crystals an igneous rock formed from magma below the surface or igneous rock cooled from lava on the surface?
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
