Desert is a color that resembles the color of the flat areas of a desert.. The first recorded use of desert as a color name in English was in 1920. [12]The normalized color coordinates for desert are identical to fallow, wood brown and camel, which were first recorded as color names in English in 1000, [13] 1886, [14] [a] and 1916, [16] respectively.
The Kelso Dunes are composed of five stacked sets of dunes, each set corresponding to a period of climate change over the last 25,000 years. During dry climate episodes, a decrease in stabilizing vegetation exposed surface sand to wind erosion, which ultimately brought the sand to the dunes (most of the eastern part of the Kelso dunes was formed when nearby Soda Lake and Silver Lake dried into ...
The Grand Erg Oriental (English: 'Great Eastern Sand Sea') is a large erg or "field of sand dunes" in the Sahara Desert. Situated for the most part in Saharan lowlands of northeast Algeria, the Grand Erg Oriental covers an area some 600 km wide by 200 km north to south. The erg's northeastern edge spills over into neighbouring Tunisia.
Dune fields in the Australian desert. Sand dunes of the Empty Quarter to the east of Liwa Oasis, United Arab Emirates. A dune is a landform composed of wind- or water-driven sand.
Ibexes are effectively flattened by countershading, making them nearly invisible against a desert background. There are three in the image. Countershading is observed in a wide range of animal groups, both terrestrial, such as deer, and marine, such as sharks. [17] It is the basis of camouflage in both predators and prey. [18]
The image was taken near the North Pole of Mars, spring 2010. Objects about 25 centimetres across are resolved on this image, which is about one kilometre wide. Close ups of some parts of this image show billowing plumes indicating that the sand slides were occurring at the time of the photo; see center left.
The sand sheet is the largest component of the system, comprising sandy grasslands that extend around three sides of the dune field. Almost 90% of the sand deposit is found in the sand sheet, while the remainder is found in the dune field. Small parabolic dunes form in the sand sheet and then migrate into the main dunefield.
In 1964, as part of a plan to develop a new corporate image for British Railways, a number of experiments were tried: Two Class 31 diesel locomotives were painted in trial liveries. No. D5578 was painted in an unlined Light Electric Blue, [1] and No.D5579 was painted in a colour variously described as Bronze Gold [1] and Golden Ochre. [2]
