What are some interesting facts about the earth's core?

In: Science [Edit categories]

Answer:

The Earth's core consists of an inner core and outer core.
The inner core is:
- solid (made of iron and nickel) due to the immense pressure there
- suspended by the liquid outer core
- believed to have a temperature like that of the sun's surface.
- only 1.7% of the Earth's mass

The outer core is:
- liquid (made of iron and nickel, also some other lighter elements)
- about 4400 °C- 6100 °C in temperature
- 30.8% of the Earth's mass.
- important for life on Earth because it's motion forms the Earth's magnetic field; without it, the charged particles of the solar wind could strip away the Earth's atmosphere or irradiate the surface, making life unlikely
