Why is the molten metallic outer core and the magnetic field important to life on Earth?
A) If we did not have the molten core and the magnetic field, we would be bombarded by meteorites and we would not be able to hold the moon in orbit.
B) If we did not have the molten core and the magnetic field, the earth would not have plate tectonics and would be covered entirely by water.
C) If we did not have the molten core and the magnetic field, we would be bombarded by cosmic rays that would strip away our atmosphere.
D) If we did not have the molten core and the magnetic field, the atmosphere would be very different with either too much ammonia and methane or too little oxygen and water.
