LEARNING PROGRESSIONS

● Scientists use Earth rocks, zircon crystals, moon

ESS.2.5 Engage in argument from evidence for how the simultaneous co-evolution of Earth’s systems and life on Earth led to periods of stability and change over geologic time. Examples could include how microbial life on land increased the formation of soil, which in turn allowed for the evolution of land plants or how the evolution of corals created reefs that altered patterns of coastal erosion and deposition providing habitats for the evolution of new life forms. (LS4.D, ESS2.D, ESS2.E)

rocks and meteorites to determine Earth’s age.

● Plate tectonics has

changed the surface of the Earth over time. ● Early life likely began between 3.9 and 3.5 bya. ● All dinosaurs, except birds, and many other organisms became extinct during a mass extinction event at the end of the Mesozoic. ● The Cenozoic is known as the Age of Mammals. ● Fossil evidence suggests

that modern humans appeared during the Pleistocene.
