How long does it take to make uranium?
The isotope U-238 has a halflife of 4.5 billion years, roughly the current age of the earth. As the sun is expected to consume the earth in about 6 billion years from now, less than 1.5 halflives will have passed by then. Therefore uranium will remain in the environment as long as earth exists, although at slowly decreasing levels.
How earth will destroy after 30 years?
I do not expect the Earth to be destroyed until about 3 billion years from now. We have lots of time.
What is a naturally occuring isotope?
It is an isotope that occurs in nature, and is not manmade. Isotopes, by the way, are atoms that have the same number of protons, but different number of neutrons. The atomic number is the same, but atomic weight (or mass) is different. For instance, Carbon can be Carbon 10, 11, 12, or 14. They are all carbon.
What is the percent of abundance of mercury on earth?
Less than 0.01 percent.Mercury's abundance in Earth's crust is 85 parts per billion by weight, 9 parts per billion by moles.The most abundant naturally forming isotope is 202Hg is at 29.86%.
What is the difference between a stable isotope and a unstable isotope?
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.

Disadvantage of mercury on the earth?
You probably mean "abundance of mercury on Earth". Its abundance in Earth's crust is 85 parts per billion by weight, 9 parts per billion by moles. The most abundant naturally forming isotope is 202Hg is at 29.86%.

How many people are there on the earth currently?
As of 2022, there are approximately 7.9 billion people on Earth. The world's population continues to grow at a rate of about 1.1% per year.

What basis do evolutionists use to determine the world is 4.5 billion years old?
Isotope dating from rocks is the main method that is used. Zircon crystals that formed on Earth have been dataed to over 4 billions years old. Dating has also been done on rocks fromt he moon, which formed shortly after earth did, to nearly 4.6 billion years.
What happened to the earth 700 billion years ago?
Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
Was the earth around 7 billion years ago?
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
How old does scientific evidence suggest the Earth is?
== == The age of the Earth is roughly 4.6 billion years.
