What are Magnetic stripes on the sea floor caused by?
Magnetic stripes on the sea floor are caused by the alternating polarities of Earth's magnetic field. As magma rises and solidifies at mid-ocean ridges, it locks in the magnetic orientation of the Earth's field at that time. Over time, as the Earth's magnetic field reverses, these magnetic stripes are preserved, providing a record of past magnetic field variations.
Why does the earth have its own magnetic field?
The Earth has its own magnetic field because of the movement of molten iron and nickel in its outer core. This movement generates electrical currents, which in turn create a magnetic field. The magnetic field plays a crucial role in protecting the Earth from harmful solar radiation and helps in navigation for animals that rely on Earth's magnetic field for direction.
What are sudden disturbances in earth's magnetic field called?
Sudden disturbances in the Earth's magnetic field are called magnetic storms. These storms are typically caused by solar wind interacting with Earth's magnetosphere, resulting in fluctuations and disturbances in the magnetic field. Magnetic storms can affect a variety of technologies such as power grids, satellites, and communication systems.
How long does it take for the Earth's magnetic field to reverse?
The Earth's magnetic field can take thousands of years to reverse.
An instrument which is sensitive to small changes in the earth's magnetic field is a?
A magnetometer is an instrument that is sensitive to small changes in the Earth's magnetic field. It is commonly used to measure variations in magnetic fields caused by geological structures, archaeological artifacts, or natural phenomena like auroras.

Earth's magnetic field is caused by?
The liquid outer-core.
Along with the spin of the Earth what causes its magnetic field?
The Earth's magnetic field is caused by the movement of molten iron and nickel in its outer core. This creates a dynamo effect, generating electric currents that produce the magnetic field.
What are sources make up the earths magnetic field?
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
Why does the earth have its own magnetic field?
The Earth has its own magnetic field because of the movement of molten iron and nickel in its outer core. This movement generates electrical currents, which in turn create a magnetic field. The magnetic field plays a crucial role in protecting the Earth from harmful solar radiation and helps in navigation for animals that rely on Earth's magnetic field for direction.
What is caused by the revolution of the earth?
The day-night cycle (obviously), the tides, and the Earth's magnetic field.
Why is the earth magnetic full detail?
The earth has a magnetic field which is similar to a magnetic bar tilted 11 degrees. This is caused because of the North and South pole.
Lunar phases are caused by motions of?
it is caused by gravity, force, and magnetic field, even the earth's atmosphere
What has caused the zebra pattern'' in the rock of the ocean floor?
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.
What has caused the zebra pattern in the rocks of the ocean floor?
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.
Does the earths magnetic field cause the earth to tilt?
No, the Earth's magnetic field does not cause the Earth to tilt. The tilt of the Earth's axis, also known as obliquity, is believed to have been caused by the gravitational influence of other planets during the early formation of the solar system. The Earth's magnetic field is generated by the movement of molten iron in its outer core.
How strong is the Mercury and magnetic field compared to the Earth?
Mercury has a weak magnetic field, about 1% as strong as Earth's. Earth's magnetic field is generated by its outer core, which produces a powerful magnetic field that protects the planet from solar winds and cosmic radiation. Mercury's magnetic field is thought to be caused by its partially liquid core and is much weaker due to its smaller size and slower rotation.
