Question

A topographic map has a scale of 1:110,000. From this ratio, we know that a horizontal map distance of 1 cm on this map will correspond to a real-world distance of cm. Also, a 6 inch map distance will correspond to a real-world distance of inches. Which of the following statements regarding paleomagnetism is false? Iron-rich volcanic rocks can act as records of the past orientations of the Earth's magnetic field for particular locations The paleomagnetic timescale, in the absence of additional stratigraphic or isotopic information, is not an absolute time scale An important benefit of the paleomagnetic timescale is its potential value in the correlation of strata Ocean sediments can't act as records of past orientations of the Earth's magnetic field The polarity of the Earth's magnetic field is known to have periodically reversed The chain and branched decay of^238 U ultimately ends with production of this stable element: Variation in the rate of production of^14 C over time is expected to be produced by: variation in oceanic circulation patterns variation in the amount of water vapor in the atmosphere variation in factors such as the intensity of the cosmic-ray flux of the Sun or the strength of the Earth's magnetic field variation in the sizes of continental ice sheets production of^14 C in the upper atmosphere is unlikely to have varied through time

Explanation / Answer

1) 110000 cm, 660000 inches

2) ocean sediments cant act as records of past orientations of the earths magnetic field.

3) The stable element will be a stable isotope of lead

4) variations i factors such as intensity of suns cosmic ray flux or the strength of the Earth.s magnetic field.
