another event?

Answer 1

Answer:

Explanation:

They usually depend on the strata, which are layers of rock, to know fossil age by looking at them, if a fossil was more on the top of the strata than another one, it’s the later one

Answer 2

Basically, Fossils in rock gives information about what animals or plants lived in the past.

The reason is because when those organism dies, they decay and form silts which goes deep into the lithosphere over million of years.

Therefore, Scientist can use the technique called the Radiocarbon dating to find out the age of the fossils. Another technique are used to find the type of organism that has existed.

Therefore, in conclusion, through the use of these techniques, the scientists can derive evidence that an event happened as far back as million years ago on earth.
