100% guaranteed. i just took the test :)
Thank you!! Connexus 6th Grader is correct! 100%
If you have a a question 9 the answer is b
Every single quartz crystal I have experienced, fractures.
this is correct for 7th grade connexus unit 9 lesson 4. i know this because i didnt listen to answers that were given and got one wrong. it was b on the first. the rest were right.
The correct answer is B. fracture.
Quartz often displays a conchoidal fracture, which means it breaks with smooth, curved surfaces. This type of fracture is commonly seen in materials with a uniform internal crystal structure, such as quartz.
But how can you determine this without already knowing the answer? With some basic knowledge, you can make an educated guess. Here's how:
1. Understand the terms: Cleavage refers to how minerals break along distinct planes of weakness due to their internal structure. Luster refers to the appearance of a mineral's surface when it reflects light. Flat planes refer to the presence of smooth, even surfaces on mineral crystals.
2. Analyze the question: The question asks how quartz breaks, not how it appears or the presence of flat planes. This suggests that we should focus on the breaking behavior.
3. Consider quartz's properties: Quartz is a hard mineral with a consistent crystal structure characterized by tightly bonded silicon and oxygen atoms. These properties make it more likely to break with a conchoidal fracture, rather than cleaving along specific planes due to its internal structure.
By applying this reasoning, we can confidently select the answer B. fracture as the most suitable option.
