Scientists can find out when the volcano erupted by determining the age of the fossils in the ashy layers of sediment in area.
<h3>What is a Volcano?</h3>
This is defined as a vent or opening where lava erupts on to the surface of the Earth.
The age of the fossils in the ashy layers of sediment in area will help to determine the time when the volcano erupted.

B & D
Protons and neutrons are energy particles found in the nucleus of atoms.
Explanation:
The forces that hold the protons and neutrons together in the nucleus are called strong nuclear forces. These forces are attractive over short distances and repulsive over long distances. This is why protons that are positively charged are held together in the nucleus despite their repulsive tendencies. However, as the nucleus gets larger because of the larger number of protons and neutrons in the nucleus, the distance with which the string nuclear forces are attractive is surpassed.
The binding energy in the nucleus will, therefore, be surpassed by the repulsive forces of strong nuclear forces over long distances causing the atomic nucleus to lose some neutrons.
