每天都有不同的沙丘 Each day a different dune

阿尔及利亚撒哈拉沙漠的沙丘

撒哈拉沙漠横跨北非300多万平方英里，覆盖阿尔及利亚、埃及、摩洛哥、苏丹和突尼斯等国的大部分地区。巨大的沙丘、岩石高原和偶尔出现的绿洲创造了独一无二的景观。尽管撒哈拉是世界上最大的热带沙漠，但它支持阿拉伯树胶和棕榈树等耐旱植物，以及骆驼和狐狸等耐寒动物。有趣的特征包括其不断变化的沙丘，如今天的图片所示，其中一些沙丘超过500英尺高。这里还发现了古代岩石艺术和化石，为早期文明和史前生物提供了见解。沙尘暴很常见，它塑造了千变万化的风景，也增加了这一自然奇观的神秘感。

Sand dunes in the Sahara, Algeria

The Sahara spans over 3 million square miles of North Africa, covering large parts of various countries including Algeria, Egypt, Morocco, Sudan, and Tunisia. Vast sand dunes, rocky plateaus, and occasional oases create a landscape like no other. Although it is the largest hot desert in the world, the Sahara supports drought-resistant plants like acacia and palm trees, and hardy animals such as camels and fennec foxes. Intriguing features include its shifting sand dunes, pictured in today's image, some of which are over 500 feet high. Ancient rock art and fossils have also been discovered here, providing insights into early civilizations and prehistoric creatures. Sandstorms are common, shaping the ever-changing scenery and adding to the mystique of this natural wonder.
