MS-ESS2-2: Geoscience Processes at Varying Scales

Construct an explanation based on evidence for how geoscience processes have changed earth's surface at varying time and spatial scales.

Clarification Statement: Emphasis is on how processes change Earth’s surface at time and spatial scales that can be large (such as slow plate motions or the uplift of large mountain ranges) or small (such as rapid landslides or microscopic geochemical reactions), and how many geoscience processes (such as earthquakes, volcanoes, and meteor impacts) usually behave gradually but are punctuated by catastrophic events. Examples of geoscience processes include surface weathering and deposition by the movements of water, ice, and wind. Emphasis is on geoscience processes that shape local geographic features, where appropriate.

Assessment Boundary: none


The following assessments were created by science teachers hoping to better understand the NGSS. In most cases teachers went from standard to assessment in around an hour.  These are drafts and should be used accordingly. Feel free to improve these assessments or contribute to the collection.

Geoscience processes
Surface processes (i.e. weathering, erosion, deposition)
Size scale
 - Large (e.g. plate motion, uplift of large mountains)
 - Small (e.g. landslide, microscopic geochemical reactions)
Time scale
 - Slow (e.g. plate motion, mountain uplift)
 - Catastrophic (e.g. earthquake, volcanoes, meteor impact)
