Big Ideas
  • The composition and structure of the world's oceans are essential factors that drive thermohaline circulation, which plays a major role in Earth's climate system.
  • Thermohaline circulation is a global process influenced by temperature and salinity differences in ocean water, contributing to its periodic patterns and energy flow.
Essential Questions
  • How do the physical and chemical characteristics of ocean water drive thermohaline circulation?
  • What is thermohaline circulation, and why is it important for Earth's systems?
  • How does the periodicity of thermohaline circulation arise from ocean structure and composition?
  • What are the consequences of changes in ocean composition and structure for global circulation patterns?
  • How might shifts in ocean temperature or salinity disrupt thermohaline circulation?
