20 points describe the outer core layer of the earth dont copy from somewhere else

The outer core of the Earth is a liquid layer and it is mainly made up of the metals iron and nickel.

It's also made up of small amounts of other substances.

The outer core is responsible for Earth's magnetic field.

The outer core is the second layer of the Earth.

The outer core is basically a fluid layer of iron and nickel. And the fluid lies below the mantle kinda. The Outer Core is the second to last layer of the Earth. It basically creates the magnetic field of the Earth. It i really really hot like 4000-5000 degrees Celsius.

Hope this helped kid :)

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
