The inclusions were most likely separated from their original rock layers during the magma intrusion.
An intrusion is a body of igneous (heated rock) rock that crystallized from molten magma. Gravity influences igneous rock placement by acting on density differences between magma and surrounding wall rocks (country or local rocks).

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.
Answer:
convergent plate boundary
Explanation:
Typically, a convergent plate boundary—such as the one between the Indian Plate and the Eurasian Plate forms towering mountain ranges, like the Himalaya, as Earth's crust is crumpled and pushed upward.
