The highest oxygen level in Earth's history occurred during the Carboniferous Period, approximately 300-360 million years ago. This period is often referred to as the "golden age of insects" due to the size and diversity of insect species during this time.
The highest oxygen levels on Earth are typically found in remote areas with abundant vegetation and minimal pollution. The lowest oxygen levels can be found in very high altitudes, such as at the summit of Mount Everest, where the air is thin.
An unconformity causes a gap in the geologic record, representing a period of erosion or non-deposition that results in missing layers of rock. This gap can be caused by tectonic forces, sea level changes, or other geological events that interrupt the deposition or preserve of sedimentary layers.
Yes, there was oxygen present during the Paleozoic Cambrian period, but at much lower levels compared to today. Oxygen levels were still increasing during this time due to the evolution of photosynthetic organisms, like algae and early plants.
well.logically it just makes sense that since there is less oxygen above sea level (mt Everest roughly 1/3 of the oxygen at sea level) that there would be more oxygen below sea level. note: this is completely hypothetical and has no scientific backing whatsoever
The oxygen content of air at any altitude is always about 21%

"Tertiary" typically refers to the third level or stage in a sequence. It can also refer to the period in geologic time that followed the Mesozoic era.
The period tells you how many energy levels an atom has.
A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.

The Geologic Time Scale is broken up into several periods of time, during which there were great changes in the biodiversity on Earth. We can see distinct changes in the flora (plants) and fauna (animals of each time period. The age range of each period is determined by radiometric dating.
The period number is the same as the highest energy level containing electrons for the atoms in that period.
