Imagine you're a geologist exploring the layers of the Grand Canyon. Your task is to arrange these layers in the correct order from top to bottom based on their ages:
1. Kaibab Formation
2. Coconino Sandstone
3. Vishnu Schist
4. Supai Group
5. Tapeats Sandstone
Can you solve the puzzle and arrange these layers in the correct chronological order of formation?
Solution and Explanation:
1. The Vishnu Schist is the oldest layer in the Grand Canyon, dating back over a billion years. It forms the deepest layers of the canyon.
2. Above the Vishnu Schist is the Tapeats Sandstone, which was deposited around 550 million years ago during the Cambrian period.
3. The Bright Angel Shale, part of the Supai Group, was deposited on top of the Tapeats Sandstone during the Pennsylvanian period.
4. The Coconino Sandstone was formed around 275 million years ago during the Permian period and lies above the Supai Group.
5. Finally, the youngest layer, the Kaibab Formation, was deposited during the Permian period and forms the top layer of the canyon.
So, the correct chronological order from oldest to youngest is: Vishnu Schist, Tapeats Sandstone, Supai Group, Coconino Sandstone, Kaibab Formation.
Exploring the Grand Canyon: Nature's Majestic Wonder:
The Grand Canyon, located in northern Arizona, USA, is one of the world's most awe-inspiring natural wonders.
