2. deep ocean currents are most affected by differences in: a. temperature b. salinity c. density d. pressure
2. deep ocean currents are most affected by differences in: a. temperature b. salinity c. density d. pressure
Answer
Explanation:
Step1: Understand ocean - current factors
Deep - ocean currents are mainly thermohaline currents. These are driven by density differences.
Step2: Analyze each option
Temperature and salinity affect density. But the direct driving force for deep - ocean currents is density differences. Pressure has less impact on deep - ocean current formation compared to density.
Answer:
C. density
