What evidence supports the hypothesis that Earth is 4.6 billion years?

Among other things, rocks have been found that are over 4 billion years old. The age of such rocks is determined by radioactive dating. Note that this is not "a" method, but perhaps 40 different methods (depending on the isotopes involved), which complement one another.
The exact age of the Earth is harder to determine exactly; but basically, it must be at least as old as the oldest rocks found.

The age of Earth is determined through radiometric dating of rocks and meteorites, as well as studying the decay of radioactive elements, such as uranium and thorium, in Earth's crust. Additionally, analysis of lunar rocks from the Apollo missions provided further evidence supporting the estimated age of Earth at 4.6 billion years.

Geological evidence of the age of the earth includes?
Geological evidence of the age of the earth includes radiometric dating of rocks and minerals, sedimentary layering, and evidence of past climate changes in ice cores and sediment cores. These methods provide a wealth of information that supports the current estimate of the earth's age of approximately 4.6 billion years.
How does Wegener's hypothesis explain why earth's surface must be moving?
Wegener's hypothesis of continental drift suggests that the Earth's surface must be moving because he observed evidence such as matching coastlines, similar rock formations, and identical fossil distributions on continents that are now far apart. This supports the idea that the continents were once connected in a single landmass (Pangaea) and have since drifted to their current positions.
What is the die theory of the earth?
The die theory of the Earth is a debunked hypothesis that suggests the Earth is hollow and inhabited by a hidden civilization. This theory is not supported by scientific evidence and is considered pseudoscience. Mainstream geology and seismology provide strong evidence that the Earth is a solid, layered structure with a molten core.
What is the hypothesis of an earthquake?
The hypothesis of an earthquake is that a sudden release of energy stored in Earth's crust causes seismic waves to propagate, resulting in ground shaking. This hypothesis is supported by observations of seismic activity, fault movements, and geological evidence.
What is a approximate age of the earth?
The Earth is estimated to be around 4.5 billion years old. This age is determined through radiometric dating of rocks and meteorites, as well as other geological evidence.
How old does scientific evidence suggest the Earth is?
Scientific evidence suggests the Earth is approximately 4.5 billion years old. This age is determined through radiometric dating of rocks and meteorites, as well as other geological processes.
How many years did earth exist before there was evidence of life on?
Earth is estimated to be around 4.6 billion years old, and evidence of the first life forms dates back to about 3.5 billion years ago, in the form of fossilized microorganisms. This means there were around 1.1 billion years of Earth's existence before evidence of life appeared.
Do fossil records indicate there has been life on earth for 6 billion years?
No, the fossil record does not indicate life on Earth for 6 billion years. Fossil evidence suggests life has existed on Earth for around 3.5 billion years. The age of the Earth is estimated to be around 4.5 billion years old.
What happened 3.8 billion year ago?
About 3.8 billion years is about the age of the oldest firm evidence of life on Earth.
Fossil evidence supports the origins of life on Earth earlier than years ago.?

What did foucault's pendulum provide in th 19th century?
evidence that supports the conjecture that the Earth is rotating
What evidence indicates that our solar system is about 4.5 billion years?
The main evidence is from radioactive materials on Earth, as well as their by-products.
How is the hypothesis about Earth's earliest life forms consistent with fossil evidence?
I know you have a textbook so use it
Are the dinosaurs the hypothesis of earth?
No, dinosaurs are neither a hypothesis nor is there a "hypothesis of Earth".
Is Venus Earth's twin?
Some scientists have theories and evidence that prove this hypothesis, but there's no way of knowing for sure.
What evidence of Earth's climate in the past supports the theory supports continental drift?
There are fossils of animals that can only live in warm whether, that are all around the world, even on Antarctica
When did life first begin?
There is evidence of life on Earth since around 3.7 billion years ago.
