Answer:</h2>
The Nazca plate forms the southeastern part of the Pacific plate.
<h2>
Explanation:</h2>
- The Nazca Plate, named after the Nazca region of southern Peru.
- The Pacific Plate lies beneath the Pacific Ocean.
- The Nazca and the Pacific plate share both divergent and transform type of plate boundary.
- The Pacific and the Nazca plate are separating at an increasing rate of about 122-142mm/year. These are the regions where the rate of tectonic activity is very high.
- The Nazca Plate and the South American Plate are also converging at a rate of about 62mm/year, being the fastest subduction rate on earth.
Result: Nazca plate forms the southeastern part of the Pacific plate.
Carbon-14 appears to be decreasing by the centuries with the amount of carbon-14 dropping. If we look at the start of our graph, before it starts dropping, we see that it is 5,730 years, which means 5,730 years is your answer.
