GENERAL
2. Wind blowing over the ocean
surface drives an ocean current and if the wind stops abruptly the
current continues to flow. This flow is known as
1. geostropic motion
2. inertial motion.
3. motion with friction.
4. buoyancy driven motion.
Answer: 2
Explanation:-
On a non-rotating earth: In
the absence of friction or any other force, a current of water set
into motion in the ocean on a horizontal pressure surface (i.e., no
pressure gradient force) would simply continue forever in the same
direction at the same speed (i.e., at constant velocity). On our
(rotating) earth: In the same situation, that water will feel the
continual pull of the Coriolis force at right angles to the velocity,
and will begin to move in a circle. This is called inertial motion.
Inertia means an object in motion to remain in motion, while an
object at rest will remain at rest unless acted on by an external
force. It's a fundamental property of mass.
