Ocean fossils found on the rocky mountains are because of tectonic plates crashing.
Early scientific attempts st determining Earth's age gave a number that was around 4.6 billion years old.
<h3>Radiometric dating methods</h3>
The age of rocks can be most determined by radiometric dating.
This process of radiometric dating makes use of two different isotopes of a sample.
It is known that Radioactive isotopes break down within a known amount of time and this enables geologists to determine the age of a sample with the aid of equipment like thermal ionization mass spectrometer.

ANSWER: Constructive interference
Explanation: The amplitudes of in phase points on overlapping waves add up to make a result of a larger amplitude.
ANSWER 2: Destructive interference
Explanation: The amplitudes of out of phase points on overlapping waves subtract to make a resultant with a smaller amplitude
ANSWER 3: Wave interference
Explanation: Two waves overlap.
12.56 because you multiply the radius by 2 then multiply that by 3.14
C) French Antilles because it was a firmer French colony
