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.
Geologic maps are most recognized by their contour lines which represent different elevations. The correct option among all the options that are given in the question is the last or the fourth option. Geologic maps are important for all geologists around the world. I hope the answer comes to your help.

Answer:
Trees serve as natural filters so the effect on water quality would be so much you prob couldn't use or drink. it could also make to much water so the watershed could not handle it causing to create more rivers and more and multiple and frequent flooding, to much water, and other bad things.
