The aztecs and ancient egyptians both built pryamids because

Because they believed that the structure should be the house of their deities, and where their rulers should rest, among the gods.

Explanation:

Like several ancient societies, the Aztecs and Egyptians built pyramids for religious purposes. Even if these civilizations are separated by the distance and the time, they share similarities. The idea to connect the terrain world with the gods was something shared by both societies, and the pyramid was the structure responsible to do so. An interesting point about the pyramids of both civilizations is that they were built following severe astronomical rules. If it's the way to talk with gods, and the connection of both worlds, so the structure should be correctly arranged with the stars and the sky. No matter if it was bald like the Aztecs pyramids or pointed like the Egyptians ones, there should be the place where the gods would live, where they must pray, and most importantly, the resting place of the king.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
