how were layer cake formations produced in gansu china
Zhangye National Geopark Zhangye Danxia is known for the unusual colours of the rocks, which are smooth, sharp and several hundred meters tall. They are the result of deposits of sandstone and other minerals that occurred over 24 million years. The result, similar to a layer cake, is connected to the action of the same tectonic plates responsible for creating parts of the Himalayan mountains. Wind, rain, and time then sculpted extraordinary shapes, including towers, pillars, and ravines, with varying colours, patterns, and sizes.[3]
Sponge cake The Victoria sponge, also known as the Victoria sandwich or Victorian cake,[12] was named after Queen Victoria, who was known to enjoy a slice of the sponge cake with her afternoon tea. The sponge part evolved from the classic pound cake â€“ equal quantities of butter, sugar, eggs and flour. The difference was the Victorian creation of baking powder, which was discovered by English food manufacturer Alfred Bird in 1843, which enabled the sponge to rise higher.[13][14] This invention, writes cookery author Felicity Cloake, "was celebrated with a patriotic cake", Victoria sponge.[13]
