2.3 percent. The toxins in asphalt corroded the animals skins causing bleeding and leading to death. Also, the toxins polluted water for drinking, poisoning them.
The early supercontinent that existed when Earth's landmasses were joined together was called Pangaea.
There are smallamount of volcanoes. They emit so2 and co2 gases.
Carbon dioxide used to make up most of Earth's early atmosphere.
Earth's aphelion position occurs approximately six months after its perihelion position. Perihelion, when Earth is closest to the Sun, typically occurs around early January, while aphelion, when Earth is farthest from the Sun, usually takes place in early July. This timing is a result of Earth's elliptical orbit around the Sun.
One important factor leading to early diversification of animals was the development of body plans that allowed for different functions and roles within ecosystems. This enabled early animals to exploit various environmental niches and adapt to different ecological challenges. Additionally, evolutionary innovations such as segmentation and bilateral symmetry played a key role in facilitating diversification among early animal groups.
Most asphalt is obtained as a byproduct of the distillation of petroleum or other natural materials. Some natural asphalt, however, is extracted from organic mineral deposits in the early stages of their breakdown

They started to farm so they can have a reliable food source . They also needed to because the earths temperatures began to rise so the mammoths and other large animals began to die.
The project is in good shape and should finish early and within budget
