Answer:
The isotope you would use to date a fossil from paleozioc era is the 47 billion years half-life 87rb as the paleozoic era dates from 540 to 248 million years ago.
Explanation:
Sometimes geologists need to estimate older fossils, like the ones from the paleozoic era which is the oldest of the three eras.
Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast and it is useful to date fossils younger than about 75,000 years.
To date most older fossils and to estimate how long ago rocks formed, geologists use unstable radioactive isotopes of elements, decaying at constant, and this is called radiometric dating, rocksadiometric dating or radioisotope-dating of igneous rocks or ash located above, below or around the fossil vecinity.
Answer:
A crescent moon is defined as the moon phase that is a few days after a new moon. A gibbous moon is the moon phase that is between the first quartet and the full moon. and Waxing is the phase of the moon when it is growing in size from new moon to full moon. • Waning is the shrinking phase of the moon when it is decreasing in size from full moon to new moon when it cannot be seen at all by us.
