There are many types or strains of marijuana, however they basically fit into two egories; Indica and Sativa. Breeders will often cross strains to change the growing or properties of the original. As a rule of thumb, generally Indicas tend to be shorter, stockier plants with smaller, denser and smellier buds.
· Look for contact points where different rock types come together at a 90 degree angle. These contacts resulted in high pressure and high temperature conditions that would commonly produce gold. You will find that many of these areas will have some historic workings, there are still areas out there that are "textbook" contact zones that are very rich with gold that have never been mined.
· Different types of excavators work better on various terrains. Tracked excavators offer excellent traction and stability on hilly and soft ground, while wheeled excavators work best on hard and flat surfaces. However, the weight of an excavator also impacts how well it performs on specific terrain.
All are different and typically correspond to the color the asteroid reflects, as well as the shape. For example, as of this guide, Icy core asteroids (ones you need to blow up) only have 1 shape.
