Land definition includes soil, structures, vegetation and vertical extent, shaping property rights and conveyance interests. The term land is a comprehensive legal concept including soil, every species of ground, waters and marshes, and also houses and other buildings so that conveyance of the land carries structures upon it; it extends vertically above and below the surface, and judicial usage is context-sensitive-practical actors may conceive land narrowly while legal analysis treats immovably fixed items (such as standing trees, fences and stones) as part of the land.
