What is the date the earth was formed?
well in many believes is that the earth was always here and will always be.
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.
A well-defined group of objects that transfer energy to one another?
A system is a well-defined group of objects that transfer energy to one another. This transfer can take place as a result of mechanical work, heat, or electromagnetic radiation within the system. Systems can be open, closed, or isolated depending on the exchange of matter and energy with their surroundings.
Is earth an open or closed system in terms of matter?
Earth is a closed system in terms of matter, meaning that no new matter is added from outside the system. Matter can cycle within the Earth's systems (such as the water cycle or carbon cycle), but it does not enter or leave the planet.
When was the Earth founded?
Authorities mostly agree that the age of the Earth is about 4.54 x 109 years. This agrees with the age of the Sun according to stellar growth and luminosity models, and also agrees with meteor dating. The dating is done by radiometric methods. The oldest rocks on the Earth (in Australia) are in excess of 4 x 109 years old. The Universe is about three times as old.
Why can't radiometric dating be used with accuracy on metamorphic rocks?
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
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 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 are ingenue rocks the best types of rock samples for radioametric dating?
Igneous rocks are the best types of rock samples for radiometric dating because they form from the cooling and solidification of molten material, which allows for the incorporation of radioactive isotopes at the time of their formation. This provides a clear starting point for measuring the decay of these isotopes over time. The closed system nature of igneous rocks, where no parent or daughter isotopes are lost or gained after formation, enhances the accuracy of dating. Common examples used in radiometric dating include basalt and granite.
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 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 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.
The age of the solar system is estimated by the dating of rocks. t or f?
True. The age of the solar system is estimated primarily through radiometric dating of the oldest rocks on Earth and meteorites, which are believed to have formed around the same time as the solar system itself. These methods indicate that the solar system is approximately 4.6 billion years old.
How are igneous rocks the best type of rock sample for radiometric dating?
Igneous rocks are the best type of rock sample for radiometric dating because they form from the solidification of molten material, which allows them to incorporate radioactive isotopes at the time of their formation. This process creates a closed system where the parent isotopes and their decay products remain isolated from external influences, providing a clear record of the time since the rock crystallized. Additionally, the predictable decay rates of isotopes, such as uranium-lead or potassium-argon, enable precise age determinations. This makes igneous rocks particularly valuable for dating geological events and understanding the timing of Earth's history.
Scientists have been able to estimate the age of our solar system by dating?
Scientists estimate the age of our solar system by dating the oldest meteorites, which are remnants from its formation. Radiometric dating techniques, particularly uranium-lead dating, have been used to determine the age of these meteorites, yielding an age of about 4.56 billion years. This age reflects the time when solid materials began to condense from the solar nebula, marking the formation of the solar system. Additionally, the ages of the oldest lunar rocks and samples from other celestial bodies support this estimate.
