<u>Answer:</u>
C- The water was a constant shallow sea during that time.
This was happened to the Grand Canyon area during the Permian Age.
<u>Explanation:</u>
The Grand canyon consists of the most studied sequence and complete rock on earth. They are nearly 200 million to 2 billion of years old, of which most of them were deposited in shallow, warm seas and near the ancient and the sea shores which were long gone.
The youngest formation of rock in the grand canyon is the Kaibab Limestone, which was laid down during the Permian age by the advancing warm and shallow sea. Although, the areas climate has been changing constantly during recent times from cool and wet pluvial to semi arid conditions. And also, with less water to cut, the erosion has also reduced greatly.
During and after WWI, America experienced rapid growth due to the fact that pretty much the rest of the western civilization was demolished. American businesses were selling to Europe, and obviously earned a lot of profit. There was a lot of opportunity, and people wanted to spend their extra money on fun things. Advertisers and Marketers capitalized on that, and started a shift into more consumeristic thinking. With the advent of electricity, tons of home appliances were created and marketed, emphasizing the "buy now and pay later" approach. With all of the kitchen appliances, the era of domesticity ended, and women were free to go do other things such as have jobs or pursue fun activities.
The economy thrived, money was created out of nothing (compound interest, etc), which lead to a bubble and eventual collapse in 1929.
Hope this helps! :)
