Dating lunar rocks
Children can see snapshots of the Moon's history and hold an important artifact of American history with a Lunar Sample Disk.This activity may stand alone, but it is recommended as a station in in which plants grow. Other types of regolith include volcanic ash, materials deposited by a glacier or river, sand dunes, the red rocky surface materials of Mars, and the layer of material on the lunar surface. Describe the technological effort and national pride involved in sending those astronauts to the Moon.If Borg’s team is correct, either the moon’s primordial magma seas are much younger than current theory allows, or FANs developed another way – a blow to the moon’s magma ocean theory as a whole.Hence, the study could mean big things to lunar scientists.If the FANs are not derived from a magma ocean, one of the key observations that led to the magma ocean hypothesis is invalid.
Clarify that they might have heard of radiometric dating using the element carbon-14 (carbon dating), but carbon is only one of the elements scientists can use to determine the age of a substance.
Scientists thought the Earth and moon were approximately the same age, about 4.57 billion years old.
But a new analysis of lunar rock samples suggests that Earth’s moon is 200 million years younger than the previous estimate.
The team looked at levels of lead and neodymium isotopes in lunar samples from the Johnson Space Center, using new techniques to improve upon previous similar studies.
They found lunar sample 60025 to be 4.36 billion years old, about 200 million years younger than prior estimates.
