Answer:
The answer is a highly developed nation with an aging population
Answer:
The answer is Option B, 3 half-lives.
Explanation:
Potassium–argon dating (K–Ar dating) is a radiometric dating method. It measures the radioactive decay of an isotope of potassium (K) into argon (Ar). Potassium is a common element found in many materials like clay and certain minerals. The technique is best suited to dating minerals and rocks more than 100,000 years old. For shorter timescales, it is unlikely that enough argon (40 Ar) will have accumulated. This dating method is used by geologists and paleoanthropologists in order to understand very great expanses of time and the deposits that the earth has formed. One paleoanthropological example of how the technique has been used is in bracketing the age of deposits at Olduvai Gorge where hominin remains have been found. The scientists have dated lava flows above and below the deposits where fossils have been found. Other paleoanthropological discoveries have also been dated using this technique. It is well suited to sites that show evidence of volcanic activity, as in the case of East African sites like Hadar, Ethiopia.
Answer:I can think of many things that extrapolating on incomplete data can cause. First and foremost, the subject of climate change and the use of fossil fuels. If we continue down the path of green emery, the country will become so poor. There is not enough data to forecast what the cost of this green energy will cost the average house hold.
Explanation:
Answer:
C. FOCUS
Explanation:
Focus is the point where the rock starts to fracture. It is referred to as the origin of the the earthquake. Also, known as the hypocenter, vibrating energy from the hypocenter travels in all directions. It's the point where rupture starts.
Epicenter is usually misinterpreted as the focus, but epicenter is actually the point on land that is directly above the focus. It isn't the starting point, but it's the point on the land that's above the starting point.
