The answer is D. The Palaeozoic era was characterized by the supercontinent of Pannotia which was located at the current position where Chile is, 500 million years ago. There is evidence that shows that central Africa was once at the polar regions due to evidence of glaciers in its geological rocks. Due to tectonic movement, the Appalachians and the Ural Mountains were formed in the resulting Pangea supercontinent.
The Continental Divide divides the region into two large drainage areas. To the east of the Divide, waters, flow to the Arctic Ocean, to the Hudson Bay, or to the Atlantic oceans through the Mississippi River system. To the West, they flow into the Pacific Ocean. Hope this helps. ;)

Answer:
The true statement is:
d. It is impossible to know which contains more energy.
Explanation:
In this scenario, the frequencies of Photon A and Photon B were not given. This makes it impossible to know which photon contains more energy than the other. Note that the amount of energy is directly proportional to the photon's electromagnetic frequency but inversely proportional to the wavelength. A description of the associated wavelengths was offered, but this description is not enough to help determine the energy of each photon. In conclusion, the photon's frequency determines its energy level just as the wavelength reduces its energy.
