Earth Science Overview

Earth science studies the physical structure, materials, processes, and history of Earth as an integrated planetary system. This discipline examines the atmosphere, rocks, minerals, water systems, oceans, fossils, landforms, climate patterns, tectonic activity, erosion, sedimentation, and the long-term changes that shape the planet’s surface and interior. It includes atmospheric science, geology, hydrology, oceanography, and paleontology, each of which focuses on a major part of Earth’s natural systems. By studying earth science, learners gain a framework for understanding how air, water, rock, life, energy, and time interact to shape environments, natural hazards, resources, landscapes, climate, and the history of life on Earth.

Categories

• Atmospheric Science

  Study Earth’s atmosphere, including weather, climate, air pressure, wind, clouds, storms, atmospheric chemistry, radiation balance, and interactions between the atmosphere and surface.

• Geology

  Examine Earth’s rocks, minerals, landforms, tectonic plates, volcanoes, earthquakes, erosion, sedimentation, geologic time, and the processes that shape the planet’s crust.

• Hydrology

  Explore the movement, distribution, storage, and quality of water across rivers, lakes, groundwater, watersheds, precipitation, runoff, infiltration, and the water cycle.

• Oceanography

  Learn about the oceans, including currents, waves, tides, marine chemistry, seafloor geology, ocean circulation, coastal systems, and interactions between oceans and climate.

• Paleontology

  Study fossils and ancient life, including fossil formation, extinction, evolution, ancient environments, geologic history, and evidence used to reconstruct life in the past.
