Allowing the public to interact with mock-ups at trade shows is part of the R&D process, as it enables engineers to see how consumers will interface with products. A trade show is an organized meeting held over the course of several days where members of a certain industry demonstrate their products or services.
Typical landforms include hills, mountains, plateaus, canyons, valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins.lementary landforms (segments, facets, relief units) are the smallest homogeneous divisions of the land surface, at the given scale/resolution. These are areas with relatively homogeneous morphometric properties, bounded by lines of discontinuity.
Continents and oceans are considered to be the most basic landforms, and the arrangement of smaller landforms within these bodies is known as topography, for continental features, and bathymetry, for undersea features.
