I’ll give the Brainliest to who answers these question with a reasonable explanation.

1. Why is it important for Earth’s magnetic field that the inner core is hotter than the outer core?

A. The inner core provides the heat source for outer core convection.

B. The inner core provides the energy for Earth’s orbit around the Sun.

C. The inner core’s heat produces the Coriolis effect needed for rotation.

D. The inner core’s heat allows the outer core to conduct electricity.

2. What does the Earth’s magnetic field reveal about the structure of the Earth’s layers?

A. That the mantle is solid.

B. That the outer core is solid.

C. That the outer core is liquid.

D. That the mantle is liquid.

1.) The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.

2.)The Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.

Answer:

1. A. The inner core provides the heat source for outer core convection.

The inner core is hotter than the outer core allows for the bottom of the outer core to be heated. As this happens, it expands and rises up to the top of the layer. As it rises, it cools and sinks back down to the bottom, just to be warmed again. This is convection and is one of the requirements for a magnetic field.

2. That the outer core is liquid.

The Earth’s magnetic field shows that the outer core must be liquid. The magnetic field comes from the Earth’s core, and in order for a magnetic field to be achieved, there must be a fluid material for things such as convection.
