We did a lab where we sieved types of rocks. Big rocks, medium rocks, small rocks, pebbles, sand, dust. i read the question over and over again but I don't get what it's asking me. Can you please help me find the answer to the questions? The question is, ' What can you infer about the geologic past of the religion where OUR sample was collected? In two sentences, address the structural geology and the wearthering agents.'
