Explanation:
A rigid hierarchy refers to one where people who are born into a certain position in life, find it quite hard to move from it or rather one where there are different social classes and people had to be classified in one class for the system to work.

Because there weren't enough big brains out there to cover all of the major things and that there we're major time periods of things.
Explanation:
The tundra is a biome on the Earth that covers approximately 20% of its land mass, and it is almost exclusively located in the Northern Hemisphere. It is an environment that helps in the regulation of the CO2 in the atmosphere, and it is one of the biggest natural CO2 sinks. The living organisms in the tundra, are using the CO2 for their needs, thus removing parts of it from the atmosphere, and when they die, because the tundra is cold, and the decomposition is very slow, most of the CO2 remains trapped, and doesn't go into the atmosphere.
Unfortunately, the global warming is slowly changing the tundra, and prolongs the summer periods, thus reducing the permafrost period of the year, so the decomposition of the living organisms is getting quicker, and also bigger percentage of the CO2 from them gets to the atmosphere.
The location is in the Levantine Sea.
Explanation:
The Levantine Sea is located in the eastern part of the Mediterranean Sea, thus it can be said that it is a subdivision of it. The borders of this sea are comprised of Egypt on its south, Turkey on its north, Syria,Lebanon, Israel, and the Gaza strip on the east, Aegean Sea on the northeast, and Mediterranean Sea on the west. This sea is located in the warmest part of the Mediterranean, thus it has the warmest waters, as well as the highest salinity.
The largest and best known island in the Levantine Sea is Cyprus, and it is also the only sovereign country in it, though it can also be said that there are two separte countries on the island. The sea has three subdivisions, one of which is the Cilician Sea, while the other two are the Gulf of Iskenderun and Gulf of Antalia. This Sea is very important for the region, especially because it has a direct connection with the Red Sea, so it is one of the most exploited trading routs in the world.
Some characteristics of this sea are:
- depth of 4,384 m
- area of 320,000 square km
- the Nile River flows into it
- it is located in a highly geologically active area
