CURRICULUM TOOL: GEOLOGIC HISTORY GEOLOGIC TIME NYS Earth Science Core Curriculum Performance Indicator 1.2 Describe current theories about the origin of the universe and solar system. Major Understandings: 1.2d Asteroids, comets, and meteors are components of our solar system. Impact events have been correlated with mass extinction and global climatic change. Impact craters can be identified in Earth’s crust. 1.2h The evolution of life caused dramatic changes in the composition of Earth’s atmosphere. Free oxygen did not form in the atmosphere until oxygen-producing organisms evolved. 1.2i The pattern of evolution of life-forms on Earth is at least partially preserved in the rock record. Fossil evidence indicates that a wide variety of life-forms has existed in the past and that most of these forms have become extinct. Human existence has been very brief compared to the expanse of geologic time. 1.2j Geologic history can be reconstructed by observing sequences of rock types and fossils to correlate bedrock at various locations. The characteristics of rocks indicate the processes by which they formed and the environments in which these processes took place. Fossils preserved in rocks provide information about past environmental conditions. Geologists have divided Earth history into time units based upon the fossil record. Age relationships among bodies of rocks can be determined using principles of original horizontality, superposition, inclusions, cross-cutting relationships, contact metamorphism, and unconformities. The presence of volcanic ash layers, index fossils, and meteoritic debris can provide additional information. The regular rate of nuclear decay (half-life time period) of radioactive isotopes allows geologists to determine the absolute age of materials found in some rocks. Performance Indicator 2.1 Use the concepts of density and heat energy to explain observations of weather patterns, seasonal changes, and the movements of Earth’s plates. Major Understandings: 2.1o Plate motions have resulted in global changes in geography, climate, and the patterns of organic evolution.
