The scientific study of all aspects of Earth
The way a scientist approaches a problem; steps include observing, formulating a hypothesis, testing, and evaluating results
A plausible, but yet to be proved, explanation for how something happens.
A hypothesis that has been tested and is strongly supported by experimentation, observation, and scientific evidence.
A portion of the universe that can be separated from the rest of the universe for the purpose of observing changes that happen in it.
Reactions that enhance (positive) or retard (negative) change in an open system.
Earth system science
The study of Earth as a closed system composed of interacting open systems and how the open systems may be changed as a result of human activities.
Earth's innermost compositional layer, where the magnetic field is generated and much geothermal energy resides
The middle compositional layer of Earth, between the crust and the core.
The outermost compositional layer of the solid Earth: part of the lithosphere.
Earth's outermost rocky layer, comprising the crust and the uppermost part of the mantle.
A layer of weak, ductile rock in the mantle that is close to melting but not actually molten.
The movement and interactions of large fragments of Earth's lithosphere, called plates.
The thinner, denser, and younger part of Earth's crust, underlying the ocean basins.
The older, thicker, and less dense part of Earth's crust; the bulk of Earth's land masses.
Useful materials obtained from the lithosphere, atmosphere, hydrosphere, or biosphere
A resource that can be replenished or regenerated on the scale of a human lifetime.
A resource that cannot be replenished or regenerated on the scale of a human lifetime.
A model that describes the movement of water through the reservoirs of the Earth system; the water cycle.
The process by which water changes from a liquid to a vapor.
The process by which water taken up by plants passes directly into the atmosphere.
The process by which water changes from vapor into a liquid.
The process by which water changes from a vapor into a solid.
The process by which water that has condensed in the atmosphere falls back to the surface as rain, snow, or hail.
Precipitation that drains over the land or in stream channels.
The process by which water works its way into the ground through small openings in the soil.
A body of water that flows downslope along a clearly defined natural pathway.
The clearly defined natural passageway through which a stream flows.
The steepness of a stream channel.
