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.

• 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
