An artist's conception shows a terraformed Mars in four stages of development.. Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on.
A typical wood splitting maul has a head mass of 6 to 8 lb or approximately 2.7 to 3.6 kg, respectively. Traditionally, mauls have a wedge-shaped head, but some modern versions have conical heads or swiveling sub-wedges. The original maul resembles an axe but with a broader head. For splitting wood, this tool is much better than a typical axe.
A cleaving axe or cleaver is a form of axe used within green woodworking to split wood lengthways. Cleaving (riving) is used to turn a log into lumber or billets (short or thick pieces of wood) into firewood. Splitting axe is sometimes described as an old name for a splitting maul [1] or froe.

A froe. A froe (or frow), shake axe or paling knife is a tool for cleaving wood by splitting it along the grain. It is an L-shaped tool, used by hammering one edge of its blade into the end of a piece of wood in the direction of the grain, then twisting the blade in the wood by rotating the haft (handle).
A mattock (/ ˈ m æ t ə k /) is a hand tool used for digging, prying, and chopping. Similar to the pickaxe, it has a long handle and a stout head which combines either a vertical axe blade with a horizontal adze (cutter mattock), or a pick and an adze (pick mattock).
Adze: A variation featuring a head perpendicular to that of an axe. Rather than splitting wood side-by-side, it is used to rip a level surface into a horizontal piece of wood. It can also be used as a pickaxe for breaking up rocks and clay. Hatchet: A small, light axe designed for use in one hand specifically while camping or travelling.
An axe hafted with an adhesive. Hafting is a process by which an artifact, often made of bone, stone, or metal is attached to a haft (handle [1] or strap). This makes the artifact more useful by allowing it to be launched by a bow (), thrown by hand (), or used with more effective leverage ().
