Clarification Statement - S.5.ESS.2.1.CS:
Examples could include the influence of the ocean on ecosystems, landform shape, and climate; the influence of the atmosphere on landforms and ecosystems through weather and climate; and the influence of mountain ranges on winds and clouds in the atmosphe

Assessment Boundary - S.5.ESS.2.1.AB:
Assessment is limited to the interactions of two systems at a time.

Science and Engineering Practices - 3-5.SEP2.2:
Develop a model using an analogy, example, or abstract representation to describe a scientific principle.

Disciplinary Core Ideas - S.5.ESS.2.1.DCI:
ESS2.A: Earth Materials and Systems •Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). These systems interact in multiple ways to affect Earth’s surface materials and processes. The ocean supports a variety of ecosystems and organisms, shapes landforms, and influences climate. Winds and clouds in the atmosphere interact with the landforms to determine patterns of weather.

Crosscutting Concepts - CC3.2:
A system can be described in terms of its components and their interactions.
