← HS-ESS2-1
HS-ESS2-3 →

Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to Earth’s systems.

Clarification statement: Examples should include climate feedbacks, such as how an increase in greenhouse gases causes a rise in global temperatures that melts glacial ice, which reduces the amount of sunlight reflected from Earth’s surface, increasing surface temperatures and further reducing the amount of ice. Examples could also be taken from other system interactions, such as how the loss of ground vegetation causes an increase in water runoff and soil erosion; how dammed rivers increase groundwater recharge, decrease sediment transport, and increase coastal erosion; or how the loss of wetlands causes a decrease in local humidity that further reduces the wetland extent.

Performance Level Descriptions

Every Regents exam question on HS-ESS2-2 is written to match one of the performance level descriptions (PLDs) below.

Level 1: Using geoscience data/information, identify one change in Earth’s surface or an Earth system and how it will result in a change to another Earth system. August 2026 Question 42, August 2026 Question 29, August 2026 Question 34, June 2026 Question 49, January 2026 Question 24, June 2025 Question 3, June 2025 Question 36
Level 2: Identify the geoscience data/information that provides evidence for a given claim that a change to Earth’s surface or an Earth system results in a change to another Earth system or provides evidence to support/refute a given claim that a change to an Earth’s surface or one Earth system results in a change to another Earth system. August 2026 Question 31, January 2026 Question 42, January 2026 Question 12, June 2025 Question 5, June 2025 Question 43, June 2025 Question 9, June 2025 Question 22, June 2025 Question 14
Level 3: Analyze geoscience data/information to support the claim that a change to Earth’s surface or an Earth system can create a feedback that cause changes to one or more Earth’s system(s). June 2026 Question 25, January 2026 Question 47, August 2025 Question 24, June 2025 Question 6, June 2025 Question 44, June 2025 Question 25, June 2025 Question 11
Level 4: Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to Earth’s systems. January 2026 Question 29, August 2025 Question 38, August 2025 Question 9
Level 5: Compare and contrast various geoscience data sets to examine consistency of measurements and observations in order to make the claim that changes to Earth’s surface can create feedbacks that influence the stability of Earth’s systems over time.

NGSS Dimensions

Performance expectation HS-ESS2-2 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices
  • Analyzing and interpreting data: Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.
Disciplinary Core Ideas
  • Earth Materials and Systems: Earth’s systems, being dynamic and interacting, cause feedback effects that can increase or decrease the original changes.
  • Weather and climate: The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.
Crosscutting Concepts
  • Stability and change: Feedback (negative or positive) can stabilize or destabilize a system.
  • Influence of engineering, technology, and science on society and the natural world: New technologies can have deep impacts on society and the environment, including some that were not anticipated. Analysis of costs and benefits is a critical aspect of decisions about technology.
