4,968,000,000 years, 4,531,900,000 years and 4.969999999 x years are reasonable approximations for the age of the Earth, given the approximation "Earth is approximately 5x10^9 years old." Correct options are A, C and E. The approximation "Earth is approximately 5x years old" is in scientific notation, and it represents a value around 5 billion ...
Earth is approximately 4.57 billion years old. Explanation: Earth is approximately 4.57 billion years old. This age is determined through various radiometric dating methods, including uranium-lead dating and potassium-argon dating. These methods involve measuring the decay of radioactive isotopes within rocks and minerals on Earth.
The Earth has been though many changes that have affected all of Earth’s spheres: the biosphere, geosphere, hydrosphere, and atmosphere. Geologists use clues from Earth’s history to determine the age. Scientists estimate the age of the Earth to be 4.6 billion years old. What evidence do scientists have that would help them make that estimation?
