Yes, it is true. It is almost 3 miles high
Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
Because light travels more than 800 thousand times as fast as sound does.
the economy of Japan is a highly developed and market-oriented economy. It is the third-largest in the world by nominal GDP and the fourth-largest by purchasing power parity (PPP). ... Due to a volatile currency exchange rate, Japan's GDP as measured in dollars fluctuates widely.
so the answer would be C. it is sa highly developed economy
It was the most accurate calendar of the time!
