CK-12 Foundation's Earth Science FlexBook Covers the following chapters: What is Earth Science- scientific method and branches of earth science. Studying Earth's Surface- landforms, map projections and computers/satellites. Earth's Minerals- types, formation, identification , properties and uses. Rocks- rock cycle and types of rocks. Earth's Energy- renewable and nonrenewable resources. Plate Tectonics- Earth's interior, continental drift, seafloor spreading, tectonic movement, plate boundaries, and landforms. Earthquakes- causes, prediction, safety, seismic waves/tsunamis, and rock/mountain building. Volcanoes- formation, landforms and types of magma and eruptions. Weathering and Formation of Soil- mechanical/chemical weathering and soil formation, horizions & climates. Erosion and Deposition- actions of water, wind and gravity. Evidence about the Earth's Past- fossilization and relative/absolute dating. Earth's History- geological time, early history and evolution. Earth's Freshwater- water cycle and lakes, rivers, streams & groundwater. Earth's Oceans- formation, composition, waves/tides, seafloor and ocean life. Earth's Atmosphere- properties, significance, layers, transfer of energy and movement of air. Weather- cloud types, air movement, storms, and forecasting. Climate- factors that affect climate, different climates, and global climate change. Ecosystems and Human Population- role, flow of matter/energy, carbon cycle and effect of human population growth. Human Actions and the Land- erosion and pollution. Human Actions and the Earth's Resources- renewable vs. nonrenewable and conservation & availability. Human Actions and the Earth's Water- usage, distribution, sources, pollution, and protection. Human Action and the Atmosphere- types, causes, effects and reductionObserving and Exploring Space- electromagnetic radiation, telescopes, and current discoveriesEarth, Moon and Sun- properties, motion, tides/eclipses, sun layers and solar activityThe Solar System- motion, formation, inner vs. outer planets, dwarf planets, meteors, asteroids, and comets. Stars, Galaxies and the Universe- constellations, light/energy of stars, classification, evolution, galaxies, dark matter, dark energy, and the Big Bang Theory.
