During a geomagnetic storm: 
  • a)
    The Earth's magnetic field weakens, allowing more solar radiation to penetrate the atmosphere. 
  • b)
    The Earth's magnetic field strengthens, shielding the planet from solar radiation. 
  • c)
    The Earth's magnetic field remains unchanged, having no effect on solar radiation. 
  • d)
    The Earth's magnetic field fluctuates, causing disturbances in the magnetosphere and ionosphere.

Geomagnetic storms occur when there is a significant disturbance in the Earth’s magnetosphere, caused by changes in the solar wind or solar magnetic field interacting with the Earth’s magnetic field. These storms can lead to fluctuations in the Earth’s magnetic field, causing disturbances in the magnetosphere and ionosphere. These disturbances can result in various effects such as auroras, radio communication disruptions, and potential damage to satellites and electrical power grids. Therefore, option D is the correct choice as it accurately describes the impact of geomagnetic storms on the Earth’s magnetic field.
