Boundary representation (B-rep) is a method in computer-aided design that represents a solid object as a combination of its bounding surfaces. These surfaces define the boundaries of the solid and can include faces, edges, and vertices. B-rep is commonly used in CAD software to precisely define the geometry of 3D objects for visualization and manufacturing purposes.
A convection boundary is the boundary at which heat or energy is transferred through convection, which is the movement of fluids (liquids or gases) due to temperature differences. This boundary marks the area where the fluid in contact with a solid surface gains or loses heat through convection.
The Moho, short for Mohorovičić discontinuity, is a boundary in the Earth's crust that separates the solid crust from the underlying mantle. So, the Moho is where the solid crust transitions into the solid mantle, but it is not a solid or liquid layer itself.
The boundary between the mantle and core is known as the core-mantle boundary. It lies approximately 2,900 kilometers below the Earth's surface. This boundary separates the molten iron-nickel outer core from the solid iron-nickel inner core.
The boundary between two phases is called a phase boundary. It represents the interface or transition region where the properties of the two phases may differ, such as in density, composition, or structure. Examples include the solid-liquid boundary in ice and water, or the liquid-gas boundary in water vapor and liquid water.
Boundary layers are typically referred to as the "viscous boundary layer" and the "inviscid boundary layer." The viscous boundary layer is the region where the effects of viscosity are significant, typically occurring near solid surfaces in fluid flows. In contrast, the inviscid boundary layer refers to the region where viscosity effects are negligible, allowing the fluid to behave more like an ideal fluid. These layers are crucial in understanding fluid dynamics, particularly in applications involving aerodynamics and hydrodynamics.
A projection is a 2 dimensional representation of a solid figure. See related link.
The boundary line is solid. If not it will be a dashed line.

Depending on the type of map you are referring to, the solid black line could indicate a national boundary. If it is a map of states, it could be a state boundary.
