Explanation / Answer
1. The best war to determine the age of precambrian Rock is radioactive dating.
Radioactive dating is a technique in which decay of radioactive elements is determined and from that the age is calculated.
2. The milankovitch discontinuity seperates Earth's mantle and outer core - False.
The Gutenberg discontinuity seperates Earth's mantle and outer core. The depth of this discontinuity is 2900km.
3. The Richter earthquake magnitude scale is based on the total amount of energy released by earthquake, as measured on a seismograph - True.
The measurement of the intensity of an earthquake using the amplitude of seismic waves. As the amplitude depends on the depth of the earthquake focus, the distance of the recording station from the focus, the travel path and local geology at both the source and receiver, such magnitude estimates need to be constrained by several determinations.
