When did turtle appear on the Earth?
prehistoric times, (when dinosaurs were alive)
When did liquid water exist?
Liquid water has existed on Earth for over 3.8 billion years, originating from the cooling and solidification of the planet's surface. The existence of liquid water is crucial for supporting life as we know it.
Why are no rocks found that date from the first 800 million years on earth existence?
No rocks from the first 800 million years of Earth's existence have been found primarily due to the processes of geological recycling and erosion. The early Earth's crust was likely hot and unstable, leading to the formation of a molten surface where any solidified rocks would have been destroyed. Additionally, tectonic activity, subduction, and erosion over billions of years have recycled and erased the oldest rocks, making them nearly impossible to find today. Thus, the absence of ancient rocks reflects the dynamic and ever-changing nature of Earth's geology.
How many years of earths history do geologists study?
4.6 billion years
Earth is approximately 4.5 billion years old. Is it likely that any of the rocks that were on Earth's surface when it first formed are still in existence?
It is unlikely that any rocks from Earth's initial formation are still in existence today. The planet's surface has undergone significant geological processes, including erosion, subduction, and volcanic activity, which continuously recycle and alter rocks over billions of years. While some ancient rocks, like certain metamorphic and igneous formations, can be billions of years old, they have been transformed from their original state. Thus, while remnants of early Earth may exist in some form, they are not the same as the original rocks present at the planet's formation.
How many years does it Halley's comet to pass earth?
over 300 years.
How many years is 20000 days on Earth?
20000 days on Earth is equal to roughly 54.8 years.
How long ago did bacteria first appear on earth?
Scientists believe that the earth's atmosphere has been in existence for over 3.5 billion years. This is based on the fossil records that are found which date to so many years.
How many mustang are there on earth?

How many Camaros are there on earth?
Impossible to answer as many of those sold over the years have been destroyed.
Probability of a tsunami on the east coast of the US?
Very close to 1. Over the next 4.5 billion years that the earth is expected to remain in existence, such an event is almost certain.
How many years after Earth formed did the first dinosaur live?
Over four billion (4,000,000,000) years. A famous illustration puts it this way: if we think of the Earth's existence as one calendar year, beginning on 1 January, the dinosaurs were here just in time for Christmas. (And People? We show up just four seconds before midnight, 31 December.)
Who do you think is responsible for earth?
The Earth's existence and natural processes are a result of various scientific phenomena and processes that have occurred over billions of years. It is not attributed to any single individual or entity.
When did turtle appear on the Earth?
prehistoric times, (when dinosaurs were alive)
How many years did the dinosaurs walk the earth?
They lasted for over 160 million years until they became extinct as a result of the Earth being struck by a meteor about 65 million years ago..
What was the name of the asteroid that hit earth?
They have not been named. There have been many of them over the millions of years.
What is the total length of time that man has existed on earth?
The modern form of humans (i.e. homo sapiens sapiens) evolved about 200,000 years ago.
