Why cant carbon-14 be used to date material that is older than 75000 years?

Carbon has a half life of 5730 years. That means that after 5730 years there'll only be half the amount left. After about 11500 there will be a quarter of the original. After 75000 years there will be about 0.0001 of the original sample which is too small to date accurately?

Carbon-14 has a half-life of about 5,730 years, limiting its usefulness for dating materials older than about 50,000 years. Beyond this point, there are not enough remaining carbon-14 atoms in a sample for accurate dating. Instead, other radiometric dating methods, like potassium-argon dating or uranium-lead dating, are used for older materials.

Why is carbon14 dating not accurate for estimating the age of materials more than 50.000 years old?
Carbon-14 dating is not accurate for materials older than 50,000 years because the half-life of carbon-14 is about 5,730 years, meaning it decays rapidly over time, making it ineffective for measuring ancient material. Beyond this age, the amount of carbon-14 left in a sample is so small that it becomes difficult to accurately measure, leading to less reliable age estimates. Other dating methods, such as potassium-argon or uranium-lead dating, are better suited for older materials.
Why is potassium 40 used to date objects older than 50 000 years old?
Potassium-40 is used for dating objects older than 50,000 years because its half-life is about 1.3 billion years, allowing for dating of older materials. When potassium-40 decays to argon-40, the amount of argon-40 trapped in a sample provides a way to estimate the sample's age. This method is particularly useful for dating rocks and minerals.
Coal is formed by the compression of?
Coal is formed by the compression of dead plant material over millions of years. This organic material undergoes chemical and physical changes due to pressure and heat, transforming it into coal.
How long do disposable nappies take to decompose?
Disposable diapers can take 200-500 years to decompose in a landfill due to their plastic and synthetic material composition.
How does coal form and what is it made from?
Coal forms from the remains of plants that were buried and compacted over millions of years. It is primarily made up of carbon, along with varying amounts of other elements such as hydrogen, sulfur, and oxygen.
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
Why can't carbon 14 be used to date material that is older than 75000 years?
The half-life of carbon is roughly 6000 years. That means that every 6000 years, the amount of Carbon halves. Therefore, in a million years, the amount of carbon-14 would be so low that it would be extremely difficult to determine the exact age of the shell. So radioactive elements of longer half-lives, such as Uranium-238(half-life of 4.9 billion years) are used to date older objects.
