Ridges are elevated formations found in various natural landscapes, such as mountain ranges, the ocean floor, or the surface of a planet. They are typically made of solid materials such as rock or sediment, and are formed through geological processes like tectonic activity, erosion, or volcanic activity.

Finger prints are made by dermal ridges on the fingers. You also have much larger ridges on the palms of the hand. They prevent slipping while you are holding on to things.

The mid-ocean ridges are made almost entirely of basalt, because this is where new oceanic lithosphere is being formed. In fact, oceanic plates in there entirety are made up almost entirely of basalt.(igneous rock)

Friction ridges or fingerprints are formed by the patterns of raised skin ridges in the papillary layer of the dermis. These ridges are made up of dermal papillae, which project into the epidermis and create unique patterns that form fingerprints.
There are 119 edges on the outer side of a quarter. The ridges were made to help prevent and detect counterfeit coins.
Fingerprints are made of ridges and valleys on the skin's surface, created by the unique patterns of sweat pores, dermal ridges, and epidermal layers. The ridges are covered in sweat and oils, leaving a distinct and permanent pattern when touched on a surface.

Fingerprints are made up of a pattern of ridges and valleys on our skin's surface. The ridges are made up of sweat, oil, and skin cells, and each person's fingerprint pattern is unique due to a combination of genetic and environmental factors.

Long ridges of sediments alongside the channel of a river are called levees. They are created by the deposits which are made when a river overflows its banks.
