Clarification Statement - S.MS.ESS.2.2.CS:
Emphasis is on how processes change Earth’s surface at temporal 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

Science and Engineering Practices - 6-8.SEP6.3:
Construct a scientific explanation based on valid and reliable evidence obtained from sources (including the students’ own experiments) and the assumption that theories and laws that describe the natural world operate today as they did in the past and wil

Disciplinary Core Ideas - S.MS.ESS.2.2.DCI:
ESS2.A: Earth’s Materials and Systems •The planet’s systems interact over scales that range from microscopic to global in size, and they operate over fractions of a second to billions of years. These interactions have shaped Earth’s history and will determine its future. ESS2.C: The Roles of Water in Earth’s Surface Processes •Water’s movements—both on the land and underground—cause weathering and erosion, which change the land’s surface features and create underground formations.

Crosscutting Concepts - CC7.4:
Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.
