Question

Suppose that you gather more information about each sample, beyond a picture. (Obsidian and Gneiss, Granite and Soapstone, and Conquina Limestone and Pumice) You obtain numerical data about the rocks,(Obsidian and Gneiss, Granite and Soapstone, and Conquina Limestone and Pumice) and you learn more about their properties. What other attributes could you use to sort the rocks? Use what you know about minerals to help you.

The rocks could be sorted based on their internal composition or reflective properties. They could even be sorted based on their strength, age, or where the rocks came from.

Answer 2

where they came from, how deep in the earth they were, how old they might be, the weathering that has taken place
