Earth History Test -Observation and Inference Determine if a given statement is an observation or inference -Calcite, Limestone, Shale, Sandstone - Know how to identify a rock as limestone, shale, or sandstone using acid - Know which type of rock contains calcite and how calcite reacts to acid. -Differential erosion - Know how differential erosion effects the shape of remaining rock - Infer if specific rock layers are harder or softer than surrounding rocks based on the landform left by differential erosion -Sand -What happens to sand or rocks as they move from one place to another. Identify a specific sand as beach or river sand based on the sorting, particle size, and particle shape. Additional Vocabulary: - rock column, correlation, plateau, rock layers, rock samples, formation Earth History Study Notes: Test Friday 10/24
