That's a very long timetable from 4,500, 000,000 years ago right up to 542,000,000 years ago, a total of 3,958,000,000 years.
From low surface temperatures, with extensive glaciation to warm temperate conditions and no glaciation, which seemed to have occured in cycles over that time period.
What else can I help you with?
What is precambrian order?
85% of earths history and the earliest era that exists. bacteria mostly survived then and built up oxygen until a mass extinction.The. Era had many extinctions because of large variations in climate is what mesozoicor cenozoic or precambrian which one
Why is the shield also referred to as the Precambrian Shield?
Because it was created in the precambrian era...The Candadian Shield was formed in the Precambrian Era.The rocks of the Canadian Shield formed during the Precambrian time.
What era featured the longest periods with no life forms on Earth.?
Precambrian
Do precambrian have any plants or organisms living?
During the Precambrian era, around 4.6 billion to 541 million years ago, there were no land plants or complex multicellular organisms as we know them today. Instead, the Precambrian era was dominated by simple single-celled organisms like bacteria and algae, as well as some primitive multicellular organisms like sponges and jellyfish.
Why are more fossils found in the paleozoic era than in the precambrian era?
During the Precambrian times, life was mostly limited to single celled organisms. Life that was not single cellular didn't have any hard body part (like teeth, bones, shells, etc.) and so they weren't preserved.
What was the climate in precambrian time?
In Precambrian times, a relative shortage of volcanoes resulted in low emissions of carbon dioxide. This contributed to low surface temperature, and a lot of glaciers towards the end of the period.
What was the Precambrian era's climate?
The Precambrian is a long period and just as Earth has many climates now, it had many then.
What era of the geologic time scale was the longest?
precambrian times
What was dangerous about the precambrian times?
Old age. You were likely to die from it, back then.
How was the climate in the precambrian time?
The Precambrian refers to the 4000 million years leading up to the Cambrian. That is far to vast a period to give you a "climate" answer for. Because the Earth was so much different then (for instance it had no oxygen in its atmosphere, the tides where much bigger (as the moon was closer) and for a period the earth was completely frozen over (snowball Earth).
What did earth look like during the precambrian time?
It looked like a sphere
What is precambrian order?
85% of earths history and the earliest era that exists. bacteria mostly survived then and built up oxygen until a mass extinction.The. Era had many extinctions because of large variations in climate is what mesozoicor cenozoic or precambrian which one
When were precambrian rocks formed?
During the precambrian.
What are the Preambrian plants?
During the Precambrian period, plants had not yet evolved. The Precambrian period is characterized by simple life forms like bacteria and algae. Land plants did not appear until the Ordovician period, which followed the Precambrian.
Historians know least about era do?
**Precambrian**
What is the climate of the Atacama Desert like?
The Atacama has a cool and very dry climate. Some areas have received no rainfall in historic times.
What was the climate like in prehistoric times?
In prehistoric times, the climate of the world was very hot. Over the last 2 billion years, it has alternated between being cold and being hot.
