GENERAL GEOLOGY

Detailed explanation-1: -Longitudinal dunes are also known as linear dunes. These dunes are giant and present a parallel needle-esque feature on the landscape. Unlike the typical dunes, the longitudinal dunes are long and straight. A linear dune forms when sand is dearth or when not in excess and when the wind blows in a particular direction.

Detailed explanation-2: -Most sand dunes are classified by shape. There are five major dune shapes: crescentic, linear, star, dome, and parabolic.

Detailed explanation-3: -A large, elongated dune lying parallel to the prevailing wind direction. Longitudinal dunes usually have symmetrical cross sections. They generally form in areas that are located behind an obstacle where sand is abundant and the wind is constant and strong.

Detailed explanation-4: -Longitudinal dunes elongate parallel to the prevailing wind direction, creating parallel ridges of dunes. These occur where the sand supply is neither high or low. Transverse dunes are perpendicular to the wind direction and occur where there is an abundant source of sand.

Detailed explanation-5: -Also called linear dunes, longitudinal dunes look like large, parallel needle-esque features on the landscape. They are straight, and long, unlike the typical dune that people imagine. This dune type forms when sand is not in excess, and when wind blows in one constant direction.
