Earth's precession
Earth's ice ages are primarily thought to be caused by variations in the Earth's orbit and tilt, known as Milankovitch cycles. These cycles affect the amount and distribution of sunlight reaching the Earth, leading to fluctuations in global temperatures and the growth or retreat of ice sheets. Additional factors such as changes in greenhouse gas concentrations and volcanic activity can also influence the onset and duration of ice ages.
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
The process most responsible for the increase in early Earth's atmospheric oxygen levels is photosynthesis. This is the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into oxygen and energy. Over time, the accumulation of oxygen from photosynthesis led to the rise in atmospheric oxygen levels.
The prevailing westerlies, which blow from west to east at mid-latitudes, are responsible for most of the local weather patterns in North Carolina. These winds interact with other factors such as the Gulf Stream and Appalachian Mountains to influence the climate and weather in the region.
The process most responsible for the increase in early Earth's atmospheric oxygen levels is thought to be the evolution of photosynthetic organisms, such as cyanobacteria, which released oxygen as a byproduct of photosynthesis. This oxygen eventually accumulated in the atmosphere, leading to the Great Oxidation Event around 2.4 billion years ago.

during the middle ages, people took a religious view that society expressed god's will.
In the Middle Ages people thought that by denying worldly pleasures was a good thing. During the Renaissance people thought that enjoying worldly pleasures was a good thing.

It is thought that there were 5 major ice ages in Earthâ??s history. The most recent event was over 2 million years ago, and was in the Quaternary period.
