Standard 2.1 Organizing Data Students organize and describe data that represents: ● Earth formed along with the rest of the solar system 4.6 billion years ago. ● The early Earth was bombarded by impacts just as other objects in the solar system were bombarded. ● Erosion and plate tectonics on Earth have destroyed much of the evidence of this bombardment, explaining the relative scarcity of impact craters on Earth. Identifying Relationships Students use tools, technologies, and/or models to analyze the data and identify and describe relationships in the datasets, including: ● statistics, probability Students analyze data to identify effects of: ● The age and composition of Earth’s oldest rocks, lunar rocks, and meteorites as determined by radiometric dating. ● The composition of solar system objects. ● Observations of the size and distribution of impact craters on the surface of Earth and on the surfaces of solar system objects (e.g., the moon, Mercury, and Mars).
