Interactive Geologic Timeline Activity

Type of Resource



In this learning activity, students use a web-based geologic timeline to examine temperature, CO2 concentration, and ice cover data to investigate how climate has changed during the last 715 million years.

Performance Expectations

HS-ESS2-2   Analyze geoscience data to make the claim that one change to Earth's surface can create feedbacks that cause changes to other Earth systems.

MS-ESS2-2   Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.
