Stone

Stone is another main resource, and is usually found on Earth-like planets. You can harvest stone best with drills or pickaxes, and are not as easy to find as trees on the surface. To find Stone, you can simply explore until you see a reasonably large rock on the ground, you can also use this to dig underground, as somewhat large rock could be only the tip of the iceberg, and you might find a huge montain like formation under it, and lastly... mines, mines are the easiest and quickest thought of way of getting things. Sometimes you will find other resources inside rocks instead of just stone as well. Stone is best stored in a huge pile, or indoors inside a tall building, both so you can keep adding to your supply of Stone. You can also easily find Iron in some Stone rocks.
