5. There is no known life living in the magnetosphere. Why is the magnetosphere so important to living organisms in the biosphere? Select all that apply. Without the magnetosphere, the Sun's radiation would evaporate the Earth's water or hydrosphere. The magnetosphere helps to create the landforms on Earth's surface, making it possible for a variety of ecosystems to exist. The magnetosphere deflects much of the Sun's most destructive and harmful solar particles carried in the solar wind. By allowing the Sun's radiation to penetrate through its magnetic field, photosynthesis is possible.
