Magnetic minerals were not formed at the surface
No. At least no more than any other rocks. Almost all materials contain some trace of radioactive material.
Oxygen, nitrogen, helium and trace amounts of argon. ( among other trace amounts )
Mainly Hydrogen and Helium and other trace elements.
78% Nitrogen21% Oxygen1% Trace gases
Earth, air, fire, and water.

The pull of the magnet will over ride the earths magnetism. So the compass will react to the magnet as it passes through its field.
one is a trace fossil and the other is fulgerties. im really sure about this answer too
•The magnetic orientation of rocks of different ages can be compared to get an idea of how the position of a continent has changed over time. This is the exact answer out of the book.
You can identify them by what IS the fossil. The 3 fossils are prints, coprolite, or smooth rocks corroded by gizzards.
probably coz he has loads of tattoos but i think he rocks and i love his songs 17 forever and shake it.
Mostly iron on the inside, and silicon oxide (rocks) {or you could say "slag"} on the outside. Everything else is just trace stuff.
comet is mainly ice, and so it leaves a trace as it gets close to the sun. meteors is not made of ice, but made of metal, solids, rocks, anything that doesn't melt easily and so it does not leave a trace or particles behind.
The two rocks in question may have different percentages of the same minerals, or their method of formation could be different, which can affect the shape and size of the mineral grains. Trace minerals in the two rocks could also alter their appearance, as well as the amount of weathering the rocks have been exposed to.
When rocks are formed, usually from lava flows, the magnetic orientation of them is set as they solidify. As these rocks are affected by continental drift and other factors such as earthquakes, the original magnetic orientation remains. Using the known strengths of the earth's magnetic field over time, it is possible to then tell where these rocks originally emerged.
