Answer:
C. the movement of the Earth's plates
Explanation:
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.This movement is called plate motion, or tectonic shift.

The mixed economy of Australia is becoming more of a market economy as fewer economic decisions are made by D. Private industry.
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.
A and E are the correct answers. Bulgaria and Albania are by Macedonia, meaning its by the old Yugoslavia, witch also means its more south of Europe. Croatia is part of what was Yugoslavia, making it too far south.
The most populated region of Australia is the southeastern coast because drops grow much better there and the vast majority of Australia is desert.
