[ESS2] Earth's Systems
SCI-HS.ESS2.03 Develop a model based on evidence of Earth’s interior to describe the cycling of matter by thermal convection.
Clarification Statement:Earth Science: Emphasis is on both a one-dimensional model of Earth, with radial layers
determined by density, and a three-dimensional model, which is controlled by mantle
convection and the resulting plate tectonics. Examples of evidence include maps of Earth’s
three-dimensional structure obtained from seismic waves, records of the rate of change of
Earth’s magnetic field (as constraints on convection in the outer core), and identification of
the composition of Earth’s layers from high-pressure laboratory experiments Disciplinary Core Ideas ESS2.A: Earth Materials and Systems
-Evidence from deep probes and seismic waves,
reconstructions of historical changes in Earth’s surface and its
magnetic field, and an understanding of physical and
chemical processes lead to a model of Earth with a hot but
solid inner core, a liquid outer core, a solid mantle and crust.
ESS2.B: Plate Tectonics and Large-Scale System Interactions
-The radioactive decay of unstable isotopes continually
generates new energy within Earth’s crust and mantle,
providing the primary source of the heat that drives mantle
convection. Plate tectonics can be viewed as the surface
expression of mantle convection.
