Additionally, ancient humans may have ramped up their use of ochre. This naturally occurring pigment is composed of iron ...

This magnetic field has a north and south orientation: the North and South poles. The orientation of the magnetic field is why you typically only see aurora at the North and South poles ...

Ochre body paint may have been a form of prehistoric sunscreen that helped early humans survive a sudden increase in ...

Earth's magnetic poles usually align with the north and south poles but occasionally wander from their traditional geographic positions in a process called geomagnetic excursions due to changes in ...

This magnetic field has a north and south orientation, which currently roughly aligns with Earth’s North and South poles. Those are the sites where the field is the strongest, which is why ...

The charged particles are pulled toward the North and South poles due to Earth’s magnetic field. While that magnetic field usually protects the Earth from solar winds, the winds can occasionally ...
