Why can't radiometric dating be used with accuracy on metamorphic rocks?
Metamorphic rocks have undergone high pressure and temperature conditions that can alter their mineral composition, making it difficult to accurately determine the initial isotopic ratios necessary for radiometric dating. This can lead to inaccurate age calculations. Additionally, metamorphic processes can reset the isotopic clocks of minerals, further complicating dating attempts.
What Assumptions must be made when using radiometric dating methods?
Assumptions when using radiometric dating methods include that the initial amount of parent and daughter isotopes is known, that there has been no contamination or loss of isotopes from the sample, and that the decay rate of the isotopes has remained constant over time. It's also assumed that the system has been closed to outside influences, which could alter the decay process.
What evidence indicates our solar system is about 4.5 billion years old?
The age of the Solar System HAS TO BE at least as much as that of the oldest rocks found on Earth, other planets, or asteroids (if you assume that those rocks come from the Solar System) - and that's what has been found. And that's the approximate age of the oldest rocks found. The main methods used rely on radiometric dating.

What is the approximate age of the solar system'?
The solar system is estimated to be about 4.6 billion years old. This age is determined by radiometric dating of rocks from the Earth and Moon, as well as meteorites.
Atronomers believe that the solar system is about how many years?
Astronomers believe that the solar system is about 4.6 billion years old. This age is determined by studying the ages of rocks on Earth and meteorites from space that have been dated using radiometric dating techniques.

Why is a closed system necessary in radiometric dating?
A closed system is necessary in radiometric dating to ensure that the amount of parent and daughter isotopes in the sample has remained constant over time. This is important for accurately determining the age of the sample based on the radioactive decay of isotopes. Any loss or gain of isotopes from the sample could lead to inaccurate age calculations.
What is the use of a metal lead relating it with uranium?
The system uranium-lead is very important for radiometric dating of rocks (ages between 106 and 5.109 years).
What radiometric system applies to the Jurassic time period?
The Jurassic is an age that began about 200 million years ago and stretched for about 50 million years to about 150 million years ago. Radiometric dating can identify certain materials as being from that period, but we don't have a "radiometric system" for the Jurassic, per se. Radiometric dating is part of the radiometric (from radioactive measuring) system we use to investigate a number of different things, including the age of materials found on the earth and elsewhere.

What eons old is the world today?
Our Earth and most of the Solar System is about 4.5x109 years old. This is established by radiometric dating, commonly by the uranium - lead series.
What is the approximate age of the solar system'?
The solar system is estimated to be about 4.6 billion years old. This age is determined by radiometric dating of rocks from the Earth and Moon, as well as meteorites.
Do amphibians have an open circulatory system or a closed circulatory system?
Amphibians have closed circulatory system Closed
What is the date the earth was formed?
The Earth is estimated to have formed around 4.5 billion years ago. This age is based on radiometric dating of meteorite material from the early solar system.
Atronomers believe that the solar system is about how many years?
Astronomers believe that the solar system is about 4.6 billion years old. This age is determined by studying the ages of rocks on Earth and meteorites from space that have been dated using radiometric dating techniques.
When do scientist think the earth was formed?
Scientists believe that the Earth was formed around 4.6 billion years ago through the accumulation of dust and gas in the early solar system. This age estimate is based on radiometric dating of meteorites and rocks from Earth.
