Indicate whether the statement is true or false
You live in a seismically active area and there are steep mountain slopes that show evidence of past large landslides. A geologist uses radiocarbon dating and determines that all of the landslides are 1000 +/- 5 years old
He also determines that there is an active fault in the area that moved in the last 1000-2000 years but he can't date it precisely. Which of the following is a reasonable conclusion? A) There must have been a major drought 1000 years ago that triggered the landslides. B) Radiocarbon dating is not a good dating technique or it could separate the ages of the slides. C) There was probably an earthquake ~1000 years ago. D) There must have been people in the area 1000 years ago, and they cut down the trees that were dated for determining the age of the landslide.
