Which mechanism initiates aurora formation in Earth's atmosphere?

💡 Explanation

Magnetic reconnection destabilizes the magnetosphere because it allows solar wind particles to penetrate the Earth's magnetic field, initiating the aurora. Therefore, energy transfer via magnetic reconnection drives auroral displays, rather than drag or optical effects causing them.
