the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of information, which vary at every point on the planet's surface, as navigational markers that help ...

The chances of an asteroid as large as the width of an NFL field striking Earth continue to tick up, according to NASA. The recently discovered Asteroid 2024 YR4 now has a 2.6% probability of ...

Such reversals in the Earth's magnetic field, they'd tell you ... but in geologic terms they happen all the time. As the time line at right shows, hundreds of times in our planet's history ...

Earth's iron cycle is a very complex biogeochemical ... allows the bacteria to passively align with Earth's geomagnetic field lines in both the Northern and Southern Hemispheres.

It creates the Earth's magnetic field and is about 1,400 miles (2,300 kilometers) thick. The next layer is the mantle. Many people think of this as lava, but it's actually rock. The rock is so hot ...

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from ...
