Sun, Moon, Earth, How do they work together to help life survive? Magnetosphere

Magnetosphere: Scientists believe it comes from the liquid metals (Fe and Ni) in the outer core.

Magnetosphere: Comes from the magnetic poles not the geographic poles.

Magnetosphere: Comes from the magnetic poles not the geographic poles. –Magnetic North Pole is NW of Sverdrup Island Canada.

Sverdrup Island, Canada

Magnetosphere: Comes from the magnetic poles not the geographic poles. –Magnetic North Pole is NW of Sverdrup Island Canada. –Magnetic South Pole is off the coast of Antarctica.

South Magnetic Pole:

Magnetosphere: Comes from the magnetic poles not the geographic poles. –Magnetic North Pole is NW of Sverdrup Island Canada. –Magnetic South Pole is off the coast of Antarctica. –The magnetic poles are moving about 25 miles per year.

Magnetosphere: Magnetosphere: The volume of space inside the Earth’s magnetic field.

Magnetosphere: Magnetosphere: The volume of space inside the Earth’s magnetic field. Magnetopause: The edge of the magnetosphere.

Magnetosphere: Magnetosphere: The volume of space inside the Earth’s magnetic field. Magnetopause: The edge of the magnetosphere. Magnetotail: Where the magnetic field is drawn away by the solar wind.

Magnetosphere: Magnetosphere: The volume of space inside the Earth’s magnetic field. Magnetopause: The edge of the magnetosphere. Magnetotail: Where the magnetic field is drawn away by the solar wind. Bowshock: Where the solar winds from the sun “crush” the magnetosphere.

Magnetosphere: Protects our planet from the high energy particles that are in the solar wind.

Magnetosphere: Protects our planet from the high energy particles that are in the solar wind. –Solar wind from the sun travels at 400 km/second.

Magnetosphere: Protects our planet from the high energy particles that are in the solar wind. –Solar wind from the sun travels at 400 km/second. Van Allen belts “trap” the charged particles but let electromagnetic energy through.

Magnetosphere: Protect our planet from the high energy particles that are in the solar wind. –Solar wind from the sun travels at 400 km/second. Van Allen belts “trap” the charged particles but let electromagnetic energy through. –Electrons (negative charge and light) are trapped in the outer belt (20,000 km up).

Van Allen belts “trap” the charged particles but let electromagnetic energy through. –Electrons (negative charge and light) are trapped in the outer belt (20,000 km up). –Protons (positive charge and heavier) are trapped in the inner belt (3,000 km up).

Van Allen Belts:

Magnetosphere: Some charged particles “escape” at the magnetic poles.

Magnetosphere: Some charged particles “escape” at the magnetic poles. –They collide with air molecules and create fantastic “shows”

Magnetosphere: Some charged particles “escape” at the magnetic poles. –They collide with air molecules and create fantastic “shows” In the North: Aurora Borealis

Magnetosphere: Some charged particles “escape” at the magnetic poles. –They collide with air molecules and create fantastic “shows” In the North: Aurora Borealis In the South: Aurora Australis
