There is evidence for life on earth at least some 3,600 million years ago. So the answer is non of the above but "thousands" of millions of years.
Hundreds of millions of years
More like over 4 billion years - that's the approximate age of planet Earth.
hundreds of thousands of millions of years ago is too far in the past - the universe is only 13.75 billion years old!However I know what you are asking and the organisms divided into three parts were the "trilobites". They lived about 500 million years ago.
It is a difference of scale. Interplanetary means between planets; it takes a ray of light minutes or hours to go from a planet to another planet. Intergalactic means between galaxies; it takes a ray of light hundreds of thousands of years, or even millions of years, to travel that distance.
The pentatnic scale is the oldest scale used by humans. It has appeared in folk music from around the world in songs that are hundreds, sometimes thousands of years old. It is thought that ancient Greek and Roman music used the pentatonic scale. It was not "invented" by one person.
Hundreds of millions of years
The proportion of dissolved salts in seawater has remained relatively stable over millions of years. It is primarily maintained through a balance of inputs from sources like rivers and outputs through processes like evaporation.
No, Fossilization takes hundreds of millions of years.
For hundreds and millions of years
In the atmosphere. Hundreds of millions of years ago.
A plate will subduct for tens to hundreds of millions of years.
The formation of buttes occurs on a geological timescale. This can be from millions to hundreds of millions years.
because it takes hundreds of millions of years to form.
A plate will subduct for tens to hundreds of millions of years.
The Ozark Mountains are hundreds of millions of years old.
The heavy bombardment phase of the solar system lasted from about 4.1 to 3.8 billion years ago. During this period, the inner planets, including the Earth, experienced intense impacts from leftover debris in the solar system. This phase played a crucial role in shaping the surfaces and atmospheres of these planets.
There are fossil fuels because things (like plants and animals) died hundreds of millions of years ago. Most Fossil fuels are non- renewable. Meaning they will not replenish untill we are dead and gone for hundreds of millions of years.
