What has occurred when rocks formed millions of years ago show the location of the magnetic poles at the time of their formation?

Magnetism is a property of certain materials, usually metals, that have an electric dipole on the molecular scale. A dipole is a significant separation between the positive and negative charges in the molecule. Since electrons and protons have spin, and moving electrical charges generate megnetic fields, the dipole generates a net magnetic field. If enough dipoles are oriented in the same direction the body has a net magnetic field.
The dipoles can align when sitting in a permanent magnetic field for a long period of time, like underground in the earth's magnetic field.

Which geologic event occurred first?
"Pangaea underwent formation."
Which term is defined as the exact location where an earthquake occurred?
Epicenter
What increases runoff?
Runoff increases when vegetation has been removed, compaction (as in foot or vehicular traffic) has occurred, or the location has been developed so that the permeable area has been reduced.
Where in the US have the strongest tornadoes occurred?
The strongest tornadoes in the United States have mostly occurred on the Great Plains and in the Deep South.
How many blizzards have occurred in the US?
54
What is the definition of magnetic reversal?
A magnetic reversal is a process in which Earth's magnetic field flips its orientation, causing the magnetic north and south poles to switch places. These reversals have occurred periodically throughout Earth's history and are recorded in the rock record.
What is it called when rocks are different because Earths magnetic poles change places?
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
Which geologic event occurred first?
"Pangaea underwent formation."
What is a super continent that occurred millions of years ago?
Pangea
When did the Iron Event ocurred?
The Iron Event occurred during the late stage of Earth's formation, around 4.5 billion years ago, when iron sank to the core due to its high density, leading to the development of the planet's magnetic field.
What kind of disaster occurred during the formation of Himalayan?
It is widely believed that the disaster that occurred during the formation of the Himalayas was the Continental Drift. The Himalayas are considered to be young mountains compared to other mountain ranges on the Earth.
What advance in computing occurred with the development of the UNIVAC in 1951?
Magnetic tape storage
What statement best describes the Battle of Verdun and the Battle of the Somme?
Millions of casualties occurred without any side gaining territory
The formation of the all-black (blank) occurred in the Union?
54th Massachusetts Regiment
What are the signs of chemical change has occurred?
change in temperature formation of a precipitate color change formation of a gas disappearance of a solid new odor
Has earths magnetic field ever moved or changed?
Yes, Earth's magnetic field has changed throughout its history. This change is known as geomagnetic reversal, where the magnetic north and south poles switch places. This phenomenon has occurred multiple times over the millions of years of Earth's existence.
What is the correct sequence of events that occurred during the evolution of the Universe?
Many events occurred after our Universe began to expand from an infinite state of density, including inflation, baryogenesis, quark formation, hadron formation, lepton domination, photon domination, nuclear formation, matter domination, recombination, re-ionization, star formation, galaxy formation.
