The three types of radiometric dating are potassium-argon dating (good for dating volcanic rocks up to billions of years old), uranium-lead dating (good for dating rocks older than 1 million years), and carbon-14 dating (good for dating organic materials up to about 50,000 years old).
Uranium dating is very useful to evaluate the age of rocks and minerals.
Uranium-lead dating is often used for dating very old rocks, as it has a long half-life of about 4.5 billion years. This allows for dating rocks that are millions to billions of years old with good accuracy.
yes
Radiometric dating is least useful for dating sedimentary rocks because they are formed from the accumulation of sediments, making it difficult to determine the original isotopic composition.
It is not useful in dating rocks. Only organic substances in terrestrial conditions. No carbon in rocks.
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.
relative dating is when you give an estimate date.
75 km is a good enough numeric format.
okay
Igneous rocks
absolute dating
