What is the difference between carbon 14 and uranium 238?
What is the difference between carbon 14 and uranium 238?
Carbon 14 can only be used to date fossils of a very recent age. Uranium 238 can only be used to date volcanic rocks of a very old age.
What is the difference between carbon dating and uranium dating?
The key difference between carbon dating and uranium dating is that carbon dating uses radioactive isotopes of carbon, whereas uranium dating uses uranium, which is a radioactive chemical element. Carbon dating and uranium dating are two important methods of determining the age of different organic materials.
How do scientists determine the dates of fossils quizlet?
Relative dating can only help scientists determine whether on fossil is older than another. Scientists use unstoppable elements that decay to determine the actual age of a fossil.
Which of the following best describes what we mean by a habitable world?
Which of the following best describes what we mean by a habitable world? A planet or moon that could support life, if any life happened to be on it. Which of the following places is not generally considered a potential home for life in our solar system?
How does the theory of inflation explain the near uniformity of the cosmic microwave background?
How does the theory of inflation explain the near-uniformity of the cosmic microwave background? Prior to rapid inflation, all regions of space were close enough to bounce radiation back-and-forth and reach the same temperature.
Is CMB a uniform?
Astronomers observe that the temperature of the cosmic microwave background (CMB) is nearly smooth and uniform. The temperature can become uniform only if distant regions of the universe can interact and exchange energy.
Who are the proponents of steady state theory?
The theory was first put forward in 1948 by British scientists Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle. It was further developed by Hoyle to deal with problems that had arisen in connection with the alternative big-bang hypothesis.
