HS-ESS2-3

SCUSD NGSS Curriculum Guide

==== **HS-ESS2-3: Develop a model based on evidence of Earth’s interior to describe the cycling of matter by thermal convection.**[Clarification Statement: 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.] ====

Key Vocabulary:

 * magma || fossils || rocks || sea floor || ridge ||
 * continental drift || convection currents || tectonic plates || tectonic forces || magnetic reversals ||
 * hot spots || asthenosphere || lithosphere || oceanic crust || continental crust ||
 * trench || fracture zone || plate tectonics || subduction zones || sea floor spreading ||
 * convergent || divergent || transform || mid-oceanic ridge || paleomagnatisim ||
 * subduction zone || rift || slab pull || ridge push || mantle plumes ||
 * mantle seismic waves || earthquakes || magnetic field || thermal energy || thermal convection ||
 * mesosphere || inner core || outer core ||  ||   ||

Possible Assessments (formative and/or summative):
Use data sets of controlled-source seismology to identify density of the different materials in the Earth.

Key Student Activity:
Use data sets of controlled-source seismology to identify density of the different materials in the Earth.

Things to Avoid/Correct:
Convection is only one of the forces moving the plates.
