What else can I help you with?
According to the precambrian rock record much of earths first free oxygen combined with?
Earth was formed somehwat less than 4.6 billion years ago. The Cambrian Era begins around 542 million years ago. Subtracting these times provides for a PreCambrian Era of around 4 billion years in length. This time period makes up around 87% of Earth's total history.
What is the name of the oldest division of time on the periodic table?
I'm going to assume you meant the Geologic Time Scale, not the Periodic Table of the Elements. In that case, the answer is the Hadean Era (which is the first in the Precambrian Eon) Although Archean Era might also be acceptable.
What era was oxygen first in?
Oxygen first appeared in the Earth's atmosphere during the Proterozoic eon, around 2.3 billion years ago, as a result of photosynthetic organisms releasing it as a byproduct of their metabolism. This period is also known as the Great Oxidation Event.
What era did oxygen breathing organisms first thrive?
Oxygen-breathing organisms first began to thrive during the Great Oxidation Event around 2.4 billion years ago. This event marked a significant increase in atmospheric oxygen levels, paving the way for the evolution of aerobic metabolism and the diversification of life forms.
What is the difference between Era liquid laundry detergent and Era with Oxi Booster laundry detergent?
Both are excellent products and will be able to provide whatever service you request of them. The difference with is the Era Oxi Booster has higher levels of cleaning agents than the Era liquid and therefore gives you overall better cleaning power.
Early organisms in the Precambrian era converted to oxygen.?
Carbon dioxide
Early organisms in the Precambrian era converted what to oxygen?
Early organisms in the Precambrian era converted carbon dioxide to oxygen through photosynthesis. This process eventually led to the increase in atmospheric oxygen levels, paving the way for the evolution of more complex life forms.
The Precambrian era converted what to oxygen?
Carbon Dioxide
Which gas did volcanoes not produce in the Precambrian era?
Oxygen
Why are there no samples from the early precambrian era?
Samples from the early Precambrian era are rare due to geological processes such as erosion, metamorphism, and plate tectonics that have destroyed or buried the rocks from that time period. Additionally, the rocks from the early Precambrian era are often heavily altered, making it difficult to study and obtain accurate data from them.
What are some events that happen during the precambrian era?
life arose and the atmosphere became enriched in oxygen
When was the Founding Era?
the Precambrian era
Historians know least about era do?
**Precambrian**
What gas was lacking from Earth in the Precambrian era?
Oxygen was lacking from Earth's atmosphere during the Precambrian era. This period of Earth's history, which spans from about 4.6 billion years ago to around 541 million years ago, is characterized by low oxygen levels in the atmosphere due to lack of photosynthetic organisms producing oxygen.
What are the subdivisions of the Precambrian era?
The Precambrian era is divided into three subdivisions: the Hadean, Archean, and Proterozoic eons. These subdivisions represent different stages in Earth's early history, from the formation of the planet to the evolution of complex life forms.
What are two subdivisions of the Precambrian Era called?
The two subdivisions of the Precambrian Era are the Hadean and the Archean Eons.
Atmosphere gases in the precambrian?
During the Precambrian era, the atmosphere was mostly composed of gases like carbon dioxide, methane, water vapor, and nitrogen. There were lower levels of oxygen compared to present-day levels. The lack of oxygen contributed to the different forms of life that existed during that time.
