中文注释:在阴霾的天空下,岩石塔(Pinnacle Rock)巍然耸立在Galápagos’ Bartolome岛上.岛上最著名的特色(曾在电影<怒海争锋>中出现)是一种侵蚀熔岩的形成物,称为凝灰岩锥. 最初火热的熔岩从现在的死火山流出,接触到海水,温度的差异引起了爆炸,成千上万的玄武岩灰薄层因此产生,最终形成了这座屹立的丰碑.作者: Sam Abell
岛 巴托洛米岛 厄瓜多尔 图片故事:高清壁纸:英文注释:Bartolome Island, Ecuador, 1986Pinnacle Rock looms under a brooding sky off the Galápagos' Bartolome Island. The island's most famous feature (it even got airtime in the movie, Master and Commander ) is actually an eroded lava formation called a tuff cone. When hot lava from a now-extinct volcano on land reached the sea, the temperature difference caused explosions, producing thousands of thin layers of basalt ash that eventually formed into this towering monument.
