What does the Earth's magnetic field do?
Protects us from radiation from the sun.
Keeps the Earth spinning.
Allows mantle convection to occur.
Acts as a shield from heat.
Generates magnets within the Earth's core.
Why is the inner core solid if it's temperature is hotter than the inner core? _________________________________
Match the correct term of Earth's layers with it's description.
Inner core
Composed of iron, nickel and the decaying radioactive elements, is the heat source for the planet
Liquid in consistency and rotates at a high speed to create Earth’s magnetic field
The layer that is not liquid and not solid, where convection occurs
Life exists on this layer which averages 29 miles in thickness
Match the correct term of Earth's layers with it's description.
Outer core
Composed of iron, nickel and the decaying radioactive elements, is the heat source for the planet
Liquid in consistency and rotates at a high speed to create Earth’s magnetic field
The layer that is not liquid and not solid, where convection occurs
Life exists on this layer which averages 29 miles in thickness

If the mantle is a putty type substance, how would it respond to stress?
It would bend and be mold-able
It would flow easily
It would crumble
It would not react
It would expand and grow
What is electromagnetic induction?
iron moving in the core creating electric currents
magma heating near the core, becoming less dense and rising, the sinking back down
finding different coordinates on a map
hydrogen fusion in the core
it is unknown
