Owner of land allowing another to use space under the ground, such as to install a sewer or gas line.
Subsurface exploration
Engineering tests performed on soils to determine conditions and ground stability prior to building.
Subsurface rights
The owner of real estate generally has exclusive rights to the soil and minerals underneath the land. Significant limitations on subsurface rights have to be disclosed in the title deed at the time of acquisition. If no restrictions are indicated, the buyer can expect to exercise full rights to the property. It is important to note, however, that in some states, the owner of land is not automatically assumed to also be the owner of the subsurface. That is, land ownership may be separated. In many areas subsurface rights can be extremely valuable because of the existence of oil, natural gas and minerals, and those must be acquired separately.
Subtropical
Very specific area, 5 to 10 degrees higher in latitude than the Tropic of Cancer of the Tropic of Capricorn.
Suburb
A town or unincorporated developed are in close proximity to a city. Suburbs, largely residential, are often dependent on the city for employment and support services; generally characterized by low-density development relative to the city.
Succession
Transfer of real estate by legal means such as through inheritance.
Successor
Individual coming later in a sequence.
Succulent
Succulents plants have leaves and/or stems which are thick and fleshy. They often have waxy outer layers that allow the plants to retain water well.
Sucker
A shoot or growth originating from the rootstock of a grafted plant, rather than the desired part of the plant. Sucker growth should be removed, so it doesn't draw energy from the main plant.
Suction
The production of a vacuum or partial vacuum, in a cavity or over a surface, so that the external atmospheric pressure forces the surrounding fluid into the cavity or causes something to adhere to the surface.
