How long has the earth existed for?
4.6 billion years ago the earth was formed
How long old do scientists believe the earth is?
Scientists estimate that the Earth is around 4.5 billion years old based on radiometric dating of rocks and meteorites. This estimate comes from studying the age of the oldest rocks on Earth and moon samples collected during space missions.
What is the name of the long deep valleys that are formed by the movement of Earths crust?
rift valleys
Where were the first organic compounds on earth probably formed?
Probably 4 billion years (out of 4.5 billion total), but the simplest ones don't leave much of a record. ------------------------------------------------------------------------------------------------------------- Simple organic compounds can be seen is space dust in distant nebulae, an are to be found in certain (contrite) meteorites which formed in the planetary nebular from which the earth condensed. Therefore they must have been present on earth as it formed.
Why do scientists save long tubes of ice?
Scientists save long tubes of ice, known as ice cores, because they contain information about past climate conditions, such as temperature, atmospheric composition, and precipitation. By analyzing the layers in ice cores, scientists can reconstruct past environmental changes and understand how the Earth's climate has evolved over time.
How long do scientists think the earth is going to stay around?
Don't scare people by asking that question.

No, but some scientists do study how the earth, the solar system and the universe came to be based on observations of the universe today and in the past and our understanding of the "laws of physics."
How was quartz formed?
it was formed from extreme pressure for a long time under the earth.
What Approximately how long do scientists think chemical evolution took?
Scientists believe that chemical evolution, the process by which simple molecules formed more complex ones, likely took hundreds of millions to billions of years to occur on early Earth. The exact timeline is difficult to determine precisely due to the lack of direct evidence, but current estimates are within that range.
What do scientists call a long period of cold climate on Earth?
yes?
Cockroaches how long on earth?

Is the earth a cube or sphere?
A long time ago- around Christopher Columbus's time- people use to think that the Earth was a cube. Scientists now know that the Earth is a sphere. There is also evidence that it is if you don't believe that - but i highly doubt that. Astronauts that have landed on the moon have seen the Earth and have taken photographs of the Earth. They show that the Earth is a sphere. All the planets that the scientists have discovered so far have all been spheres.
