Coriolis Force is directly proportional to: (A) Density of air (B) Horizontal velocity of the moving body (C) Spacing of isobars (D) Mass of the moving body (E) Sine of the Latitude
Choose the correct answer:

Correct option is D

Explanation:
The Coriolis Force is the apparent force that acts on moving bodies within a rotating reference frame, such as Earth. The magnitude of the Coriolis force is determined by the following factors:
1. Horizontal Velocity of the Moving Body (Option B): The faster a body moves, the greater the Coriolis force acting on it. The Coriolis force is directly proportional to the velocity.
2. Mass of the Moving Body (Option D): The Coriolis force increases with the mass of the object because force is related to the mass of the object being acted upon.
3. Sine of the Latitude (Option E): The Coriolis force is dependent on the sine of the latitude (sinθ), where θ is the latitude. The effect is zero at the equator (sin0∘=0) and maximum at the poles (sin90∘=1).
Information Booster:
1. Formula for Coriolis Force: Fc=2mvωsinθ Where:
· Fc = Coriolis Force
· m = Mass of the moving object
· v = Velocity of the object
· ω = Angular velocity of Earth's rotation
· sinθ = Sine of the latitude
2. Key Characteristics of Coriolis Force:
· Acts perpendicular to the direction of motion.
· Deflects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
· Does not affect stationary objects.
3. Effect of Latitude:
· The Coriolis force is zero at the equator and strongest at the poles.
· The deflection depends on the latitude of the moving object.
4. Practical Examples:
· Cyclones: The Coriolis force influences the rotation of cyclones.
· Ocean Currents: Patterns of ocean currents are shaped by the Coriolis effect.
· Ballistic Missiles: Flight paths are adjusted for Coriolis deflection.
