美国大峡谷 The Grand Canyon

美国大峡谷The Grand Canyon
大峡谷是刻在美国亚利桑那州科罗拉多河上的一个陡峭的双面峡谷。

它主要包含在大峡谷国家公园，美国第一个国家公园之一。

总统西奥多罗斯福是大峡谷保护区的主要支持者一个，并多次来狩猎和欣赏风景。

The Grand Canyon is a steep-sided gorge carved by the Colorado River in the United States in the state of Arizona. It is largely contained within the Grand Canyon National Park, one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.

The Grand Canyon is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 29 km) and attains a depth of over a mile (1.83 km) (6000 feet). Nearly two billion years of the Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While the specific geologic processes and timing that formed the Grand Canyon are the subject of debate by geologists, recent evidence suggests the Colorado River established its course through the canyon at least 17 million years ago. Since that time, the Colorado River continued to erode and form the canyon to the point we see it as today.

科罗拉多河揭露了近二十〇亿年地球的地质历史，当科罗拉多高原隆升，其支流从岩石层切割到渠道层。

虽然地质学家主体辩论的是具体的地质过程和时间形成了大峡谷，最近的证据表明，科罗拉多河在至少17万年前就开始形成。

自那时以来，科罗拉多河不断侵蚀，形成了我们今天看到的看到峡谷上的一点。

大堡礁水域提供世界上最繁忙和最多样化的海洋栖息地。

海洋生物，种类丰富。

从许多珊瑚物种到寻找布莱克马林，各种规模和物种的鱼类存在于在两者之间。

该礁的鱼类和其他海洋生物的、艺术家甚至没有想到过不同颜色将震惊游客。

它是世界552个世界遗产地区规模最大的，覆盖347000公里，有2800多礁在该地区编目下。

The waters of the Great Barrier Reef provide the world's busiest and most varied marine habitats. Marine life is in abundance. From the many species of coral to the sought after Black Marlin and all sizes and species of fish in-between. The varied colours of the reef's fish and other marine life will astound the visitor with colour combinations that artists haven't even dreamed of. It is the largest of the world 552 World Heritage Areas, covering 347,000 km There are more than 2800 catalogued reefs in the area.
