NGSS HS-ESS2-1
The Standard
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.

What This Standard Means
What Students Need to Do
- Students create a labeled model showing how processes inside Earth and at the surface shape land and seafloor features. They show that these processes work across different distances and time spans.
What Mastery Looks Like
- A strong model uses arrows, labels, and time or distance scales to connect processes with land and seafloor features. Students can explain how slow tectonic change and faster surface change act together.
Common Misconceptions
- Students may treat uplift and erosion as separate events rather than processes happening together. They may assume all changes occur quickly, or that the ocean floor is flat and unchanging.
How to Assess It
- Give students a blank continent-to-ocean cross section. Ask them to draw and label two interacting processes, their time and space scales, and the features produced.

Ways to Teach It
Build a clay landscape, raise one section, cut a stream channel, then label which processes add relief and which wear it down.
Write a claim explaining why a mountain range can rise while erosion lowers its peaks, using evidence from a process timeline.
Sort process and feature cards by spatial scale, time scale, and constructive or destructive effect, then defend one disputed match.
Compare maps of the Mid-Atlantic Ridge and Himalayas, then sketch how plate motion and surface erosion shape each region over time.
