Question

1. The name for the point at which an earthquake rupture actually occurs in the Earth is the 2. An approximate time span for a Wilson cycle is 3. The curve against which U-Pb dates are plotted to check for consistency is called and a sample that fails to plot on the curve is called 4. In general, the rocks with the highest per-unit-volume heat production on Earth are in the 5. A system for generating seismic waves for surveys based on trucks is called 6. A wave that passes through the mantle as an P-wave, through the outer core as a P-wave, and back through the mantle as an S-wave is labelled 7. Two approaches to seismic profiling are and surveys. 8. An example of a model age system used in geology is the system.

Explanation / Answer

1. Point at which Earthquake rupture occurs at the Earth- HYPOCENTER.

2. Time span for Wilson Cycle- 500 Million Years.

3. Curves against which the U-Pb dates are plotted- CONCORDIA. Samples failing to plot on the curve- discordant.

4. IGNEOUS ROCKS have the highest per-unit heat production.

5. SEISMIC SURVEYS are done through seismic waves produced through trucks.

6. PPS waves

7. Two approaches to seismic profiling: Vertical Seismic Profiling and Crosswell Seismic Profiling.

8. Example of a model age system in geology is the U-Pb dating.
