Minerals in geodes form spectacular euhedral crystals because ____________.
A) all of the elements incorporated in the crystals are in plentiful supply
B) the crystals have abundant room to grow in their hollow surroundings
C) minerals within geodes are always framework silicates
D) minerals within geodes always contain iron

Question

Quizplus · Accepted Answer

Geodes provide a unique and protected environment for minerals to grow without interference. The hollow space provides abundant room for crystal growth in all directions, resulting in large, well-formed crystals with distinct geometrical shapes. This is why minerals in geodes often form euhedral crystals. The other answer choices are not accurate, as the availability of minerals, the presence of framework silicates, and the inclusion of iron do not necessarily determine the formation of euhedral crystals in geodes.
