And so would that ability to sense Earth’s magnetic poles—the one in the studies you described about the, um, internal magnetic compass birds have. Yeah, it should be the same. FEMALE PROFESSOR:OK, so celestial bodies make good navigational aids. Anything else? MALE STUDENT:Well, for sho...
Earth has a magnetic field extending between the north and south poles. The planet's rotation around its axis and the movement of liquid iron inside the Earth contribute to creating the magnetic field. When an iron-rich minerals such as magnetite becomes hot enough it loses their magnetic prope...
Yep, every eleven years, when the magnetic activity of sunspots is peaking. The charged particles interact with Earth’s magnetic field, and they’re pulled toward the North and South Poles. Some of them make it into our upper atmosphere, where they collide with atoms—with oxygen and nitroge...

I think so. I mean we talked about using the Sun and the stars as navigational guides—and that would certainly be helpful for homing.And so would that ability to sense Earth’s magnetic poles—the one in the studies you described about the, uh, internal magnetic compass birds have.Yeah,...
Why does Earth have a magnetic field? How does wind shear affect wind turbines? What are the effects of Earth's magnetic field on ocean features? Why does magnetic field strength decrease with distance? Why does a current-carrying wire produce a magnetic field?
Professor: Think of earth as a one big giant magnet. So, earth is surrounded by a magnetic field, and we know that every magnet has a north and a south pole and things get oriented toward those poles. Earth is no exception, right?Male student: Right.Professor: Okay, keep in mind ...
How and when is earth thought to have formed?Do the magnetic poles of the earth change?How do we know?What is "space weather',and how are we on earth protected from it?How are insolation and albedo related?What is going on in troposphere?Is the water cycle an aquatic?How does it ...
An aurora refers to a brilliant band of colored light that appears in the sky near the poles of the Earth. While many people may have heard of the Aurora Borealis, the aurora that occurs in the Northern Hemisphere, there is another aurora. The other aurora is the Aurora Australis, the ...
Earth's magnetic poles also flip, but the interval between the reversals is much longer, averaging about every 300,000 years according toNASA Climate. The last pole reversal happened about 780,000 years ago. Solar cycle and sunspot activity ...
