Paragraph 3 suggests all of the following are true of rocks from Earth's upper layers and rocks from the Moon EXCEPT: 1. They contain very little gold or platinum. 2. They contain much the same trace elements. 3. They have similar ratios of the isotopes of elements that they have in common. 4. They contain most of the siderophiles from the planetary cores that were involved in a collision.
Understand the Problem
The question is asking about paragraph 3 of a text regarding the formation of the Moon and the characteristics of rocks from Earth's upper layers as compared to rocks from the Moon. It specifically seeks to identify which statement is NOT true according to that paragraph.
Answer
They contain most of the siderophiles from the planetary cores that were involved in a collision.
The final answer is they contain most of the siderophiles from the planetary cores that were involved in a collision.
Answer for screen readers
The final answer is they contain most of the siderophiles from the planetary cores that were involved in a collision.
More Information
The paragraph suggests similarities in trace elements and isotope ratios, but not that rocks contain most siderophiles from the cores.
Tips
A common mistake is assuming similarities extend to siderophiles from cores, which are not abundant in upper layers or Moon rocks.
