Notes
The rate of plate motion is not specified in NGSS, although an evidence statement for performance expectation MS-ESS2-3 says that students should "identify relationships (including relationships that can be used to infer numerical rates of change, such as patterns of age of seafloor) in the datasets about Earth features."
