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.
they start hallow without any crystals inside.
somttimes crystals, sometimes (mostly) more rock
A hollow rock with crystals might be called a geode. A geode is a type of sedimentary rock that has crystals formed inside due to volcanic heating and cooling or by other chemicals seeping into the rock.
If you go to the Pokéthlon on Thursday and Saturday you can purchase a Thunder Stone for 2500p(Pokéthlon Points). From a Woman inside the Pokéthlon Building.

A geode is a hollow stone found on the earth that is lined on the inside with crystals.
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.
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

Ice crystals inside of clouds are moved by circulating wind currents.

Geode is a rock or stone with 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.
