Its d because they are asking about whats expressing
Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.
Gravity
Gravity is a force associated with all matter, pulling matter together. The force (which is a property of mass) is directly proportional to mass.
Explanation:
As the star fuses helium atoms in its center, enormous energy is generated and the atoms have a very high kinetic energy and want to escape from the center hence create great outwards pressure. However, the great mass of the center of the star creates enormous gravitation pull towards the center of the star. This gravitational force keeps the high kinetic atoms from escaping. The atoms keep fusing until the fuel is exhausted and the star ‘dies’.
