Write a 2 page essay on Geomorphology 2.
Even though there was not difference observed, the ages given by radiocarbon dating were a bit unrealistic. The radiocarbon age-based sedimentation rate is considered unrealistic and cannot relied upon because of the fluctuations witnessed in the rate of production of carbon 14 at the top of the atmosphere. This carbon 14, older and young changes the apparent age of the samples.
It is this time range because it gives an “age plateau” whereby a wide span of real time is covered. The significant effect occurs at this point because of the combination of large influx of 14C-depleted, carbon from the oceans, and decrease in the rate of 14C production from the atmosphere causes the “age plateau”
3. What is the percentage change in the sedimentation rate from radio-carbon age based sedimentation and calibrated age-based sedimentation? Why is the radiocarbon age-based sedimentation rate not realistic?
However, the radiocarbon age-based sedimentation rate is considered unrealistic and cannot relied upon because of the fluctuations witnessed in the rate of production of carbon 14 at the top of the atmosphere. This carbon 14, older and young, changes the apparent age of the samples.
4. Note that the sedimentation rate declined 10000 to 8000 years ago. Can you provide an environmental factor (e.g climate, vegetation uplift, etc) and process-based source-to-sink explanation as this why occurred?
Climate is a major environmental factor, which may have contributed to the sedimentation decline. As the result of aridity witnessed during this period, the amount of sediment transported and deposited decline. Rain is an important factor, given water is used in the transportation of the
