Parallel ridges are elongated elevated landforms that run parallel to each other. They are typically formed by geological processes such as tectonic activity or erosion, and are common features in mountainous regions or along the ocean floor. These ridges can vary in size and shape, and play a significant role in shaping the landscape and contributing to local ecosystems.
Mid-Ocean Ridges
Long sand ridges oriented nearly parallel to the prevailing wind are called sand dunes. They are formed by the deposition of sand carried by the wind and are common in deserts and coastal areas.
The ridges in corduroy fabric are called wales. They run parallel to each other and create the distinctive ribbed texture of corduroy.
Normal faulting takes place at ocean ridges, where tectonic plates are moving apart. As the plates separate, tensional forces cause the crust to stretch and thin, leading to the formation of long, parallel normal faults that create the characteristic topography of mid-ocean ridges.

Parallel ridges and valleys are landforms that alternate in a repetitive pattern, resembling the shape of a wave. They are typically formed by the erosion of sedimentary rocks, with the ridges being more resistant to erosion and the valleys being eroded more easily. This landform can be found in mountainous regions, deserts, and coastal areas.
Such mountains are called ridges
Long ridges of sand parallel to the shore are known as sandbars. They are formed by the action of waves and currents depositing sand in shallow areas along the coast. Sandbars can shift and change shape over time due to the movement of water.
Long sand ridges oriented nearly parallel to the prevailing wind are called sand dunes. They are formed by the deposition of sand carried by the wind and are common in deserts and coastal areas.
Parallel mountain ranges are called "ranges" or "ridges." Examples include the Sierra Nevada and the Rocky Mountains in North America.
Magnetic fields are recorded by rocks in strips parallel to ridges on Earth's surface. This phenomenon is known as magnetic striping, and it provides evidence of seafloor spreading and the movement of tectonic plates over time.

Lateral moraines are parallel ridges of debris deposited along the sides of a glacier
sand ridges that rise slightly above the surface of the sea and run roughly parallel to the shore, from which it is separated by a lagoon.
These ridges are typically formed by the deposition of sediment by longshore drift or wave action. They can provide protection to the coastline by acting as a barrier against storm surges and erosion. Vegetation such as dune grasses often grows on these ridges, helping to stabilize them.
