A

(2025·河南豫北名校期中检测)Researchers have used radar (雷达) and other technologies to study a large “star” sand dune (沙丘) in eastern Morocco located in Africa.The team said it was able to get detailed data on how these dunes form and develop.

A star dune is named after its shape because it can look like a star when seen from above.These structures are very large and have a hill, or peak, at the top.They have large masses, called arms, spreading out from the peak.Star dunes are shaped by wind and other conditions in the environment.

Star dunes are common in deserts and can be found in Africa, the Middle East, China and North America.But scientists say, although there are a lot of star dunes, the formations have not been studied very much so far.

The research results recently appeared in the publication Scientific Reports.The scientists

said the star dune rises 100 metres above surrounding dunes and is 700 metres wide.The structure contains an estimated five­and­a­half metric tons of sand.

The researchers used radar that can “see” underground to look at different elements within the star dune.The science instruments that were used are designed to map all layers within the dunes.They also used a method called luminescence dating to study the age of the dune.This method uses minerals in the sand to estimate when they last received sunlight in an attempt to guess the age of the dune.

The researchers estimated the oldest parts of the base of the star dune are about 13, 000 years old.And the dune is moving across the desert at a rate of about 50 centimetres a year.The team noted the star dune experienced the most growth during the past 1, 000 years.

Star dunes make up just 10 percent of all dunes in Earth's deserts.They have also been observed on Mars and on Saturn's moon Titan.Earth's largest star dunes are found in western China's Badain Jaran desert.Star dunes also are found in places including the Namib Sand Sea in Namibia, large sand seas in Algeria and Rub' al Khali in Saudi Arabia.In North America, Great Sand Dunes National Park in Colorado contains a series of them.
