How is the formation of Earth's magnetosphere related to the structure of Earth itself? A. The magnetosphere is that area of space, around a planet, that is controlled by the planet's magnetic field. The attractive force generated by Earth's magnetic and gravitational fields, holds charged particles in this distinct pattern. B. lons and electrons, both charged particles, emitted from the Sun's surface are pulled toward Earth due to Earth's gravitational force. Because moving charged particles create both an electrical and magnetic field, the magnetosphere is forced around Earth C. Some particles from the solar wind can enter the Earth's atmosphere. The particles that enter from the magnetotail travel toward the Earth and create an electrical fieldBecause the Earth is spinning, that electrical field creates a magnetic field as well , the magnetosphere . D. Earth's core is made of magnetic elements , iron, nickel, cobalt . Earth acts as an extremely large magnet , which attracts charged particles that exist in the ionosphere and space. Because the Earth rotates , its hot, magnetic core

generates a dynamo effect, creating a magnetic field that extends into space, forming the magnetosphere. The correct answer is D.
