How have humans used phosphate minerals as a resource?
As fertilizer for crops.
To develop new technology.***
People became wealthy from mining.
What property does a mineral have if light bounces off of a mineral sample?
It is transparent.
It is refractive.
It is reflective.***
Your first answer is wrong.
Yes, fertilizer
Is the first one A?
To find the answer to the first question, you can think about the various ways in which humans have used phosphate minerals as a resource. In this case, you would find that the correct answer is "As fertilizer for crops," as phosphate minerals contain phosphorus, which is an essential nutrient for plant growth.
For the second question, you can consider the behavior of light when it interacts with a mineral sample. If light bounces off the mineral, it means that the mineral is reflecting the light, so the correct answer is "It is reflective." In contrast, if light passes through the mineral without being scattered or absorbed, the mineral is considered transparent. If the light is bent or changes direction when passing through the mineral, the mineral is refractive.
