During the Carboniferous Earth's atmosphere was more abundant in oxygen, which in turn resulted in very large insects, and the reason for the abundance of oxygen were the proportionally high numbers of producers compared to consumers.
Explanation:
The Carboniferous is a period that often is portrayed as being warm, wet, with Earth being covered with thick forests. That is partially true though, as that only describes one part of this period. Other things that are specific for the Carboniferous are the higher levels of oxygen in the atmosphere, as well as the huge insects, centipedes, millipedes, and arachnids.
The unusually high levels of oxygen in the atmosphere were a result of the abundance of producers, from cyanobacteria to trees, but not enough consumers. That led to constant pumping out of oxygen into the atmosphere, as well as extraction of carbon dioxide. One effect of the abundance of oxygen has been that the insects and their relatives achieved greater sizes, as the higher amount of oxygen enabled their growth and reaching the maximum size for animals that have exoskeletons. Another effect was that the oxygen cooled off the global climate with time, so the warm and wet climate was replaced by a long and harsh ice age.
Thins that occurred during the Carboniferous were:
- amniote egg
- enormous organic deposits that later turned into coal
- collision of Laurasia to Gondwana
- collision of Siberia to Eastern Europe

Answer:
Explanation:
Second, we find that marriage positively affects the risk of migration in the short-term, but over the longer-term the total number of marriages does not significantly affect the hazard of migration.
It is a lot like the Northern states with having snow every year, but they are different because most of Northern Canada is in the Arctic Circle.
Just as people are affected by their enviroment, people can modify their environment in a number of ways: ...
Agriculture. People cut down forests and plow grassy plains to creat farms.
Urban Growth. People build towns and cites.
Building of Dams. ...
Energy.
Answer:
A) Most amplitude and Most compression.
Explanation:
- A Sound wave is the longitudinal waves that can be caused or created by vibration and that travel through the medium.
- In the longitudinal wave, Where the wave travels the particles of the medium vibrate in the same direction.
- As the wave passes through the medium its all particles compress together and then spread it out
