How were conditions on the early Earth of more than 3 billion years ago different from those on today's Earth?
The early Earth had higher temperatures, little to no oxygen in the atmosphere, higher concentrations of carbon dioxide, and a more violent geological activity due to frequent volcanic eruptions and impact events. Additionally, the early Earth lacked the protective ozone layer present today, which allowed for intense ultraviolet radiation from the sun to reach the surface. Conditions were more conducive to the development of simple life forms in these harsher environments.

What is the average age of most diamonds on Earth?
Most diamonds are estimated to be between 1 billion to 3.3 billion years old. These diamonds are formed deep within the Earth's mantle under high pressure and temperature conditions over billions of years.
When was the earth first formed?
The Earth is estimated to have formed around 4.5 billion years ago, based on evidence from radiometric dating of meteorites and rocks. This age is determined by analyzing the oldest known rocks on Earth and dating the composition of meteorites.
When did geologic time begin?
If your question is when the earth was created, then the answer is 4.6 billion years ago. plate tectonics started to happen a few billion years later when the earth cooled enough to form a crust.
How did old earth look like?
Old Earth, also known as "Paleo-Earth," looked very different from the Earth we know today. It had a vastly different climate, with different land formations, vegetation, and animal species. Continents were arranged differently, and there were different geological and environmental conditions.
How old was earth when life appeared on it?

How long has earth had todays composition?
Earth's current composition has been evolving for approximately 4.5 billion years, since the formation of the planet. Over this time, various processes like volcanic activity, tectonic movements, and the activity of living organisms have contributed to shaping Earth's current composition.
What was life like at the beginning of earthHow is that different from life now?
When the Earth was formed, there was no life for a billion years.
