As you move away from an ocean ridge, the rocks get older.
What else can I help you with?
Sensing device that detects magnetic fields helping confirm seafloor spreading?
A magnetometer is a sensing device that detects magnetic fields and is commonly used to measure magnetic anomalies on the seafloor. By mapping these anomalies, geologists can confirm the process of seafloor spreading by identifying patterns of magnetic stripes that align with known geomagnetic reversals. This data provides valuable evidence for plate tectonics and the movement of Earth's crustal plates.
What is the name of the area surrounding earth that is influenced by earths magnetic fields?
The area surrounding Earth that is influenced by Earth's magnetic fields is called the magnetosphere. Its primary function is to protect the planet from the solar wind and cosmic rays by deflecting charged particles.
What part of an atom is responsible for producing magnetic fields?
The part of an atom responsible for producing magnetic fields is the electrons. Electrons possess a property called "spin," which generates a magnetic moment. When electrons move around the nucleus of an atom, their spinning motion creates a magnetic field. This magnetic field can interact with other magnetic fields to produce various magnetic effects.
How do magnetic bands provide evidence that tectonic plates are moving apart at mid-oceanic ridges?
Through seafloor-spreading as iron rich minerals cool they become magnetized in the direction parallel to the existing magnetic field. As the magnetic fields change direction so will the magnetized minerals, allowing scientists to record each change in the seafloor as it spreads.
Is iodine magnetic?
No, iodine is not magnetic. It is a non-magnetic element and does not interact with magnetic fields in the same way that magnetic materials, such as iron or nickel, do.
How has the history of plate movement been captured in residual magnetic fields?
The history of plate movement has been captured in residual magnetic fields through the process of seafloor spreading. As new oceanic crust forms at mid-ocean ridges, volcanic rocks record the orientation of Earth's magnetic field at the time the rock solidified. This creates a pattern of magnetic stripes on the seafloor that mirror past changes in the Earth's magnetic field and provide evidence for the movement of tectonic plates over time.
Volcanic rock shows that some layers have magnetic fields that are aligned opposite to Earths This evidence BEST fits which hypothesis?
The evidence of volcanic rock layers with opposite magnetic fields to Earth's aligns with the hypothesis of geomagnetic reversal. This suggests that Earth's magnetic field has flipped polarity multiple times throughout its history.
What evidence is there that the earths magnetic fields move?
Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
When was The Magnetic Fields created?
The Magnetic Fields was created in 1989.
Do bats use the earths magnetic fields?
Yes, some research suggests that bats may use the Earth's magnetic fields for navigation during their nightly flights. However, the exact mechanisms and extent of this ability are still being studied and are not fully understood.
What is a science experiment that demonstrates that magnetic fields cannot be blocked?
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
What do you have to add to a compass to make it in line with the earths magnetic field?
Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.
What do you need magnetic fields for?
magnetic fields are essential to production of electricity
What can be inferred about magnetic fields and paper?
Paper is not affected by magnetic fields.
How are the magnetic fields oriented in relation to the electric fields in electromagnetic waves?
In electromagnetic waves, the magnetic fields are oriented perpendicular to the electric fields.
How Rocks that have magnetic fields that point south?
rocks with magnetic fields that point south have
When was Magnetic Fields - album - created?
