What is the outer core of the earth is made up of?
the earth's outer core is believed to be a liquid from what scientists infer about it. It is located above the iner core.
How were scientist able to infer Earths age?
Scientists used a variety of dating techniques including radiometric dating of rocks, study of fossil records, and analysis of the Earth's magnetic field to infer Earth's age. By studying the decay rates of radioactive isotopes in rocks and minerals, they were able to estimate that the Earth is approximately 4.54 billion years old.
How did people find out what the center of the earth is made of?
Scientists use seismology to study the Earth's interior and infer its composition. By analyzing seismic waves and how they travel through the Earth, researchers can infer the materials and properties found in the Earth's core and mantle. This information helps scientists determine what the center of the Earth is made of.
How old do scientist the the earth is?
How old do scientists calculate the Earth
What type of data do scientists study to help them learn about the layers of the Earth?
Scientists study seismic waves from earthquakes to learn about the layers of the Earth. By examining how these waves travel through the Earth, scientists can infer information about the composition and structure of the various layers beneath the surface.
What led scientist to infer that the earth is 4.6 billion years old?
Radioactivity
Which led scientist to infer that earth is about 4.6 billion years old?
Scientists infer that Earth is about 4.6 billion years old primarily through radiometric dating of the oldest rocks on Earth and meteorites. By measuring the decay of radioactive isotopes, particularly uranium-lead dating, researchers can estimate the age of rocks and, by extension, the age of the Earth itself. Additionally, the age of the solar system, which is closely tied to Earth's formation, has been determined using similar methods on meteorites, reinforcing the 4.6 billion-year estimate.
What is the main thing scientists observe in order to learn about the earth's makeup of the earth's interior?
Scientists observe seismic waves generated by earthquakes to study the Earth's interior. By analyzing how these waves travel through the Earth and how they are reflected and refracted, scientists can infer information about the composition, density, and structure of the Earth's layers.
What do scientists infer make it a magnet?

How old do scientists believe the earth to be?
Scientists believe that the Earth is approximately 4.5 billion years old based on radiometric dating of rocks and meteorites.
Is Earth 7 thousand years old?
No. Scientists estimate that Earth is about 4.6 billion years old.
How do scientists learn about the layers of Earth?
Scientists use seismic waves from earthquakes to study the different layers of the Earth. By measuring the time it takes for these waves to travel through the Earth, researchers can infer information about the composition and structure of each layer. This technique is known as seismic tomography and has provided valuable insights into Earth's interior.
