← GeographyWhich mechanism causes thermal expansion of seawater by the GreenHouse effect increase the intensity of strom surges?
A)Increased storm size from thermal gradients
B)Elevated sea levels from steric changes✓
C)Wider storm tracks from shifted geopotential
D)Stronger winds from modified pressure
💡 Explanation
When ocean temperatures rise by Green House effect, thermal expansion occurs because water density decrease. This leads to elevated sea levels as steric changes, increasing storm surge height and inland flooding intensity. Therefore, higher tides result when combined with rising sea level, rather than the modification of storm sizes and wind stregths due to thermodynamics equations.
