   Earth's outer core is a fluid layer about 2,260 km (1,400 mi) in height (i.e. distance from the highest point to the lowest point at the edge of the inner core) [36% of the Earth's radius, 15.6% of the volume] and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. [31]

   In 2001, S. Labrosse and others, assuming that there were no radioactive elements in the core, gave an estimate of 1±0.5 billion years for the age of the inner core — considerably less than the estimated age of the Earth and of its liquid core (about 4.5 billion years) [58] In 2003, the same group concluded that, if the core contained a ...

In theory, a solar nebula partitions a volume out of a molecular cloud by gravitational collapse, which begins to spin and flatten into a circumstellar disk , and then the planets grow out of that disk with the Sun.

   [4] [5] If used as part of a summative assessment they are usually given a low weight, [6] between 10% and 25% of the total mark of the course for all problem sets put together, [3] [5] and sometimes will count for nothing if the student receives a better grade on the exam. Alternatively, problem sets may be used purely for formative assessment ...

7. Earth's magnetic field - Wikipedia

   en.wikipedia.org/wiki/Earth's_magnetic_field

   Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. [4] One stripping mechanism is for gas to be caught in bubbles of the magnetic field, which are ripped off by solar winds. [ 5 ]
