"Grounded" Natural Recordings by Native Speakers
Grounded refers to being connected to the earth or having a solid foundation, literally or figuratively. It can also mean being prevented from doing something as a form of punishment or discipline, especially for a child. For instance, a teenager might be grounded from using their phone for a week after breaking a rule.
The word "ground-based" refers to something that is situated or operating on the ground, as opposed to being in the air or in space. It can describe systems, structures, or operations that are fixed or stationary, and often rely on the surface of the Earth for support or interaction.
