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.

D.) Cultural diffusion
Define<em> diffusion</em><em>:</em>
<em>The process of spread of a feature or trend from one place to another over time.</em>
Storm-producing storms can be formed on plains or mountainous areas, depending on where the two different temperatures / humidity meet to form thunder clouds. In the United States, the dry line or the place where the moist winds move north into the spring and summer of the Gulf of Mexico, find the driest, driest winds moving to southern Canada on the Central Plains, which is why most US tornado storms come from flat plains.
