geode
When lava suddenly cools on Earth's surface. .
A geode costs $1.00 a lb.But it depends kinds of christal are inside.
Thunder Eggs are rocks containing crystals inside them. This is what makes them geodes.
The small crystals are formed outside the volcano by the cold air... the cold air cools down the igneous rock and the crystals dont have time to join together so the are small. And the big crystals are formed inside the volcano very slowly and that way they have time to join together then there are big crystals that have been formed.
Intrusive because they have large crystals and the have these because they have cooled down much slower then extrusive due to the heat inside the volcano; meaning the crystals took longer to form.

A geode is a hollow stone found on the earth that is lined on the inside with crystals.
Geo and terr mean earth. So if you want to know what a geode is, it's an EARTH shaped stone with crystals inside. etc
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.

Ice crystals inside of clouds are moved by circulating wind currents.
It is a geode. Geodes form in gas bubbles in cooled porous lava flows. Groundwater provides the minerals that crystallize inside these hollow bubbles. Eventually erosion removes the lava rock that provided the mold that shaped the outside of the geode and then humans find them (and usually cut or crack them open to look at the crystals inside).
Yes, pyrite does form cubic crystals. Pyrite can form different types of crystals, including, cuboid crystals, raspberry-like framboids, T-shaped crystals, and dodecahedral crystals.

It depends. All gemstones other than pearls and opals are crystals, but most crystals are not gemstones.
Crystals are more likely formed inside the earth because the crystals length is dependent on the time it takes to cool. On the outside of the earth it is much cooler than the inside of the earth, so crystals don't have time to form after they have reached the surface.
