Earth Science: Understanding Our Planet
Earth science integrates geology, oceanography, meteorology, and astronomy to explain our planet's structure, processes, and history. Earth science vocabulary helps us understand natural disasters, climate change, and the geological processes that have shaped Earth over 4.5 billion years.
Plate Tectonics
Earth's lithosphere is divided into ~15 major tectonic plates moving 2–10 cm/year on the semi-fluid asthenosphere. Plate movements create earthquakes, volcanoes, mountain ranges, and ocean trenches — the fundamental shaping force of Earth's surface.
Rocks and Minerals
Earth's solid materials are classified as igneous (cooled magma), sedimentary (compressed sediments), or metamorphic (transformed by heat/pressure). Minerals are the building blocks of rocks — each with a specific chemical composition and crystal structure.
Climate and Atmosphere
Earth's atmosphere (78% N₂, 21% O₂) traps heat through the greenhouse effect, enabling life. Climate — the long-term average of weather — is influenced by latitude, ocean currents, and atmospheric composition.
Water and Oceans
The hydrosphere (oceans, ice, groundwater, water vapor) cycles water through evaporation, condensation, and precipitation. Oceans cover 71% of Earth's surface, produce 50% of its oxygen, and regulate global climate through heat storage and thermohaline circulation.
