Which answer choice includes two accurate pieces of evidence for scientists' ideas about the age of earth? The oldest known earth rocks are 5.6 billion years old. Some moon rocks and meteorites have been dated as being 5.6 billion years old.

The oldest known earth rocks are 2 million years old. Some moon rocks and meteorites have been dated as being 2 million years old.

The oldest known earth rocks are 3.7 billion to 3.8 billion years old. Some moon rocks and meteorites have been dated as being 4.4 to 4.6 billion years old.

The oldest known earth rocks 13.6 million years old. Some moon rocks and meteorites have been dated as being 13.8 million years old.

C. The oldest known earth rocks are 3.7 billion to 3.8 billion years old. Some moon rocks and meteorites have been dated as being 4.4 to 4.6 billion years old.

Explanation:

To determine the age of the earth, scientists mostly study meteorites and earth rocks. Meteorites are solid debris that accumulates in space and sometimes falls from this location to our planet Earth, or other planets as well as the moon. They are estimated to be as old as the earth and are thus useful guides in determining the age of the earth. Radiometric analysis of a meteorite that once fell on the earth using uranium-lead techniques dated its age to 4.54 billion years. This age, scientists say represents the age of the earth.

Earth rocks are also used to estimate the age of the earth. The Isua Greenstone Belt which is the oldest rock on earth is estimated to be aged some 3.7 billion to 3.8 billion years old.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.
