Mt Ngauruhoe is thought to have been active for at least 2,500 years, with more than 70 eruptive periods since 1839, when European settlers first recorded a steam eruption.
These flows are still distinguishable today on the northwestern and western slopes of Ngauruhoe (Figure 4).
This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).
Radioisotope dating (also referred to as radiometric dating) is the process of estimating the age of rocks from the decay of their radioactive elements.
Blocks weighing up to 1,000 tonnes were hurled 100 m (330 feet).
However, the most violent explosions occurred on 19 February 1975, accompanied by what eye-witnesses described as atmospheric shock waves.
The straightforward reading of Scripture reveals that the days of creation () were literal days and that the earth is just thousands of years old and not billions.
There appears to be a fundamental conflict between the Bible and the reported ages given by radioisotope dating.
There are certain kinds of atoms in nature that are unstable and spontaneously change (decay) into other kinds of atoms.
For example, uranium will radioactively decay through a series of steps until it becomes the stable element lead. The original element is referred to as the parent element (in these cases uranium and potassium), and the end result is called the daughter element (lead and argon).
His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
