In the lab, I conducted tests and observed the physical properties of minerals. I combined my observations to identify the mineral samples based on their hardness, streak, color, and luster, and on how they break. I also identified rock samples based on their physical properties, such as grain size and foliation. I learned that the properties that are used to classify or group minerals and rocks can also be used to identify them. I also learned that the physical properties of rocks can tell us how they were formed. Which ideas did you include in your answer? Check all that apply.

Minerals and rocks can be classified and identified based on their physical properties.
the physical properties of minerals include hardness, streak, color, luster, and how they break.
The physical properties of rocks include texture, color, and foliation.
The physical properties of rocks can help us identify the rocks and tell us how they were formed.
