Answer
Brief Explanations:
The image shows a person using a tool to scratch a mineral. The scratch test is used to determine the hardness of a mineral by seeing if it can be scratched by another material. The streak test involves rubbing a mineral on a streak - plate to see the color of its powder. The glass plate test is related to testing if a mineral can scratch glass (a part of hardness testing but not the general name for this action).
