nts and thus many applications of the basic principle.
Examples: Archeologists may employ the well known method of carbon 14 dating.
When Rutherford announced his findings it soon became clear that Earth is millions of years old.
These scientists and many more after them discovered that atoms of uranium, radium and several other radioactive materials are unstable and disintegrate spontaneously and consistently forming atoms of different elements and emitting radiation, a form of energy in the process.
Ruapehu (about 12 km to the south), Ngauruhoe is an imposing, almost perfect cone that rises more than 1000 m above the surrounding landscape.
Eruptions from a central 400 m diameter crater have constructed the steep (33°) outer slopes of the cone.34 The Taupo Volcanic Zone, a volcanic arc and marginal basin of the Taupo-Hikurangi arc-trench (subduction) system,5 is a southward extension on the Tonga-Kermadec arc into the continental crustal environment of New Zealand’s North Island.
Potassium-argon “dating” of five of these flows and deposits yielded K-Ar model “ages” from Ar* content.503–525 (1998), and is reproduced here with the permission of the Creation Science Fellowship of Pittsburgh ( Ngauruhoe is an andesite stratovolcano of 2291 m elevation, rising above the Tongariro volcanic massif within the Tongariro Volcanic Center of the Taupo Volcanic Zone, North Island, New Zealand (fig.1).12 Though not as well publicized as its neighbor, Mt.A survey of anomalous K-Ar “dates” indicates they are common, particularly in basalts, xenoliths, and xenocrysts such as diamonds that are regarded as coming from the upper mantle.In fact, it is now well established that there are large quantities of excess K and not yet outgassed.The original atom is referred to as the parent and the following decay products are referred to as the daughter.
