Geologists determine the age of the Earth by studying radioactive decay of certain elements in rocks and meteorites, such as uranium to lead. By measuring the ratios of these radioactive elements and their decay products, scientists can calculate the age of Earth to be approximately 4.6 billion years. This method is known as radiometric dating.
What else can I help you with?
The year of the formation of the Earth?
The Earth was formed about 4.57 billion years ago when a mass of particles and gases formed a rotating cloud that eventually concentrated into what we know call Earth.
How many year can the earth exist as you know?

Did you know that the Earth is approximately 4.8 billion years old?
Yes, scientific estimates suggest that the Earth is around 4.5 billion years old. This age is determined through the study of rocks, fossils, and other methods that date the Earth's history.
What is the current age of the earth?
The earth is roughly 4.5 billion years old. We know this to be the case because we have dated rocks from the moon that old, and earth must be at least as old as our moon.
What are the two deadly gases Four billion years ago the earth's atmosphere?
The two deadly gases present in Earth's atmosphere four billion years ago were methane and ammonia. These gases were toxic to early organisms and would have made the atmosphere hostile to life as we know it today.
How old is Earth in two years?
the earth is between 4.5 and 5 billion years old don't ask how i know that i just do

How long has the earth been here?
The Earth is estimated to be around 4.5 billion years old according to scientific studies and evidence. It formed around the same time as the rest of the solar system, evolving over billions of years into the planet we know today.
Is the earth younger than we think?
I don't know what you think, I think the Earth is about 4.6 billion years old.
What is the approximate date of the earths seasons?
We don't actually know what year the earth was made. Or I don't know anyway.

How do scientist know neptune is 4.3 billion years old?
We know from dating rocks that Earth is about 4.55 billion years old and all models indicate that the planets formed around the same time, possibly with Neptune and Uranus forming a bit later.
