Why do some minerals form regular crystals and some do not? Even the same mineral, like quartz,
may form beautiful crystals or irregular blobs. What will be an ideal response?
While all minerals are crystalline solids in which their atoms are arranged in a three-dimensional
framework, some minerals grow to possess planar surfaces, sharp corners, and straight edges because
they have space to grow into their crystal form. Minerals that do not form crystals grow in proximity
with other crystals and do not have space to form a regular crystal.
