HS-ESS2-1 | Earth's Surface Processes
Develop a model to illustrate how Earth’s internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features.
Clarification statement: Emphasis is on how the appearance of land features (such as mountains, valleys, and plateaus) and sea-floor features (such as trenches, ridges, and seamounts) are a result of both constructive processes (such as volcanism, tectonic uplift, and deposition) and destructive processes (such as weathering, subduction, and coastal erosion).
Assessment boundary: Assessment does not include recalling the details of the formation of specific geographic features of Earth’s surface.
Assessment
What assessment of HS-ESS2-1 might look like on a NY state exam.
Performance Level Descriptions
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.

NGSS Dimensions
Performance expectation HS-ESS2-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and using models: Develop a model based on evidence to illustrate the relationships between systems or between components of a system.
- Earth materials and systems: Earth’s systems, being dynamic and interacting, cause feedback effects that can increase or decrease the original changes.
- Plate tectonics and large-scale system interactions: Plate tectonics is the unifying theory that explains the past and current movements of the rocks at Earth’s surface and provides a framework for understanding its geologic history.
- Plate tectonics and large-scale system interactions: Plate movements are responsible for most continental and ocean-floor features and for the distribution of most rocks and minerals within Earth’s crust.
- Stability and change: Change and rates of change can be quantified and modeled over very short or very long periods of time. Some system changes are irreversible.
