MS-ESS2-3 Earth’s Systems
|
Students who demonstrate understanding can: Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. |
Clarification Statement: Examples of data include similarities of rock and fossil types on different continents, the shapes of the continents (including continental shelves), and the locations of ocean structures (such as ridges, fracture zones, and trenches).
|
Assessment Boundary: Paleomagnetic anomalies in oceanic and continental crust are not assessed.

Analyzing and Interpreting Data:
- Analyzing data in 6–8 builds on K–5 experiences and progresses to extending quantitative analysis to investigations, distinguishing between correlation and causation, and basic statistical techniques of data and error analysis.
- Analyze and interpret data to provide evidence for phenomena.

The History of Planet Earth:
(Secondary to 8-ESS2-3)
- Tectonic processes continually generate new ocean sea floor at ridges and destroy old sea floor at trenches.
Plate Tectonics and Large Scale System Interactions:
- Maps of ancient land and water patterns, based on investigations of rocks and fossils, make clear how Earth’s plates have moved great distances, collided, and spread apart.
