How does the Earth's rotation influence wind patterns?
Description:
Creating the Coriolis effect
The Coriolis effect is a result of the Earth's rotation. It causes moving air (and water) to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection shapes global wind patterns, such as trade winds, westerlies, and polar easterlies, and influences weather systems and ocean currents.
The other options explained:
Generates lightning storms
While the Earth's rotation contributes indirectly to weather patterns, it doesn't directly generate lightning storms. These storms are primarily caused by atmospheric instability, moisture, and rising warm air.
Alters atmospheric pressure
The Earth's rotation itself does not directly alter atmospheric pressure, but it affects wind patterns that redistribute heat and moisture, indirectly influencing pressure systems.
The correct answer is: Creates the Coriolis effect.
