d)The crust below the continent is thicker than that below the ocean. The average thickness below the continent is 35-40 km while that below the ocean is 7 km. The crust below the ocean though is denser

e) Life on Earth initially developed and continues to be sustained under the protection of this magnetic environment. The magnetosphere shields our home planet from solar and cosmic particle radiation, as well as erosion of the atmosphere by the solar wind - the constant flow of charged particles streaming off the sun.
