Rotation of earth on its axis gives rise to Coriolis force.
Justification:
- Coriolis force acts on the fluid water deflecting it like it deflects the wind. This causes rivers to 'meander'.
- It deflects the wind in the right direction in the Northern Hemisphere and to the left in the Southern Hemisphere.
- Jet streams typically cover long distances and can be thousands of miles long. They can be discontinuous and often meander across the atmosphere. The meanders in the jet stream flow slower than the rest of the air and are called Rossby Waves. They move slower because they are caused by the Coriolis Effect and turn west concerning the flow of air they are embedded in.
- It is a circular depression in the surface of a planet, moon, or other solid body in the Solar System. Hence incorrect.

Coriolis force plays a role in which of the following? 1. Formation o...
The Coriolis force is a phenomenon that affects the motion of objects in a rotating frame of reference, such as the Earth. It is caused by the rotation of the Earth and the inertia of moving objects. The Coriolis force plays a role in several natural phenomena, including the formation of meanders, the direction of trade winds, and the direction of jet streams.
1. Formation of Meanders:
Meanders are bends or curves in a river or stream. The Coriolis force plays a role in their formation by causing water to flow in a curved path. As water flows downstream, the Coriolis force deflects the moving water to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection causes the water to spiral and form meanders.
2. Direction of Trade Winds:
Trade winds are prevailing winds that blow from east to west in the tropics. The Coriolis force influences the direction of trade winds by deflecting them to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection is caused by the rotation of the Earth and the inertia of the moving air. The Coriolis force helps to create the distinct east-to-west flow of trade winds.
3. Directing Jet Streams:
Jet streams are high-altitude, narrow bands of strong winds that flow from west to east. The Coriolis force plays a significant role in directing jet streams. As the Earth rotates, the Coriolis force causes the air in the jet streams to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection helps to shape the path and direction of the jet streams.
4. Impact Crater:
The Coriolis force does not directly impact the formation of impact craters. Impact craters are created when a meteor or asteroid collides with the Earth's surface. The force of the impact causes a large explosion and ejects material from the impact site. While the Coriolis force does not play a role in the formation of impact craters, it can affect the movement of ejected material after the impact, as it follows curved paths due to the rotation of the Earth.
In conclusion, the Coriolis force plays a role in the formation of meanders, the direction of trade winds, and the direction of jet streams. Therefore, the correct answer is option C (1, 2, and 3 only).
1. Formation of Meanders:
Meanders are bends or curves in a river or stream. The Coriolis force plays a role in their formation by causing water to flow in a curved path. As water flows downstream, the Coriolis force deflects the moving water to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection causes the water to spiral and form meanders.
2. Direction of Trade Winds:
Trade winds are prevailing winds that blow from east to west in the tropics. The Coriolis force influences the direction of trade winds by deflecting them to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection is caused by the rotation of the Earth and the inertia of the moving air. The Coriolis force helps to create the distinct east-to-west flow of trade winds.
3. Directing Jet Streams:
Jet streams are high-altitude, narrow bands of strong winds that flow from west to east. The Coriolis force plays a significant role in directing jet streams. As the Earth rotates, the Coriolis force causes the air in the jet streams to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection helps to shape the path and direction of the jet streams.
4. Impact Crater:
The Coriolis force does not directly impact the formation of impact craters. Impact craters are created when a meteor or asteroid collides with the Earth's surface. The force of the impact causes a large explosion and ejects material from the impact site. While the Coriolis force does not play a role in the formation of impact craters, it can affect the movement of ejected material after the impact, as it follows curved paths due to the rotation of the Earth.
In conclusion, the Coriolis force plays a role in the formation of meanders, the direction of trade winds, and the direction of jet streams. Therefore, the correct answer is option C (1, 2, and 3 only).
