CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The same techniques of radiometric dating have been used on those rocks. All the data from Earth and beyond has led to the estimated age of 4.5 billion years for our planet. determining the absolute age of something, usually through isotope analysis; yields an actual number.

Detailed explanation-2: -It is widely accepted by both geologists and astronomers that Earth is roughly 4.6 billion years old. This age has been obtained from the isotopic analysis of many meteorites as well as of soil and rock samples from the Moon by such dating methods as rubidium–strontium and uranium–lead.

Detailed explanation-3: -Scientists now know the Earth is actually 4.54 billion years old, an age built on many lines of evidence from the geologic record.

Detailed explanation-4: -By dating the rocks in Earth’s ever-changing crust, as well as the rocks in Earth’s neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.

Detailed explanation-5: -The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.
