The magnetic field of the Earth is surrounded in aregion called the magnetosphere. The magnetosphereprevents most of the particles from the sun, carried in solar wind,from hitting the Earth. Some particles from the solar wind canenters the magnetosphere..
Also, what is the role of the magnetosphere?
The magnetosphere is important because it shieldsus from interplanetary space weather. Charged particles cannoteasily cross the lines of a magnetic field. The result is that mostof the particles in the incoming solar wind are deflected aroundthe earth by the earth's magnetic field.
Beside above, what is the magnetosphere and what causes it? More specifically, the Earth's magnetosphere isthe region of space where the Earth's magnetic field is confined bythe solar wind plasma, blowing outward from the Sun. In concurrencewith that, as the Earth rotates, its hot core generates strongelectric currents that produce the magnetic field, a.k.a.magnetosphere.
Also asked, what is the magnetosphere and how does it protect the Earth?
Life on Earth initially developed and continuesto be sustained under the protection of this magneticenvironment. The magnetosphere shields our homeplanet from solar and cosmic particle radiation, as well aserosion of the atmosphere by the solar wind - the constant flow ofcharged particles streaming off the sun.
What would happen if there was no magnetosphere?
While the Geomagnetic Storm of 1989 was unusuallymassive, the solar wind is always hitting ourmagnetosphere, even during normal solar activity. IfEarth lost its magnetic field, there would be nomagnetosphere – and no line of defense, even fromweaker solar storms.

How the moon was formed?
The prevailing theory supported by the scientificcommunity, the giant impact hypothesis suggests that the moonformed when an object smashed into early Earth. Like the otherplanets, Earth formed from the leftover cloud of dust andgas orbiting the young sun.How does the magnetosphere protect us?
Significance. The Earth's magnetic field servesto deflect most of the solar wind, whose charged particles wouldotherwise strip away the ozone layer that protects the Earthfrom harmful ultraviolet radiation.What is the magnetosphere made up of?
The magnetosphere is the region of spacesurrounding Earth where the dominant magnetic field is the magneticfield of Earth, rather than the magnetic field of interplanetaryspace. The magnetosphere is formed by the interaction of thesolar wind with Earth's magnetic field.Where does the magnetosphere start?
In the upper regions of the ionosphere, beginningseveral hundred kilometres above Earth's surface and extending tensof thousands of kilometres into space, is the magnetosphere,a region where the behaviour of charged particles is stronglyaffected by the magnetic fields of Earth and the Sun.How thick is the magnetosphere?
This equilibrium region, with a characteristicthickness of 100 km (60 miles), is called themagnetopause and marks the outer boundary of themagnetosphere. The lower boundary of themagnetosphere is several hundred kilometres above Earth'ssurface.Does the Earth magnetic field reach the moon?
The Moon is outside the Earth's magneticfield for most of each month and has a negligible atmosphere,allowing solar wind particles to reach the Moon'ssurface.What causes aurora borealis?
Bottom line: When charged particles from the sun strikeatoms in Earth's atmosphere, they cause electrons in theatoms to move to a higher-energy state. When the electrons dropback to a lower energy state, they release a photon: light. Thisprocess creates the beautiful aurora, or northernlights.When was the magnetosphere discovered?
The boundary of the magnetosphere was firstdefinitely located with instruments on Explorer 10, which waslaunched on 25 March 1961.What is polar flip?
A geomagnetic reversal is a change in a planet'smagnetic field such that the positions of magnetic north andmagnetic south are interchanged (not to be confused with geographicnorth and geographic south).Is Earth going to lose its magnetic field?
The magnetic field surrounding Earth isweakening, and scientists say it could be gone in as little as 500years. The result? Earth's magnetic poles could, literally,flip upside down. Geological records show the planet's magneticfield has reversed itself before -- about 800,000 years ago --and we're due for another.Why is Earth a magnet?
The Earth behaves like a magnet becausethe Earth is a magnet. It is not a permanentmagnet, but an electromagnet. We now understand why. Deep inthe Earth, molten metal (mostly iron) flows due to heatwhich causes convection.What is the earth's magnetic field called?
Earth's magnetic field. The Earth's magneticfield, also called the geomagnetic field, whicheffectively extends several tens of thousands of kilometres intospace, forms the Earth's magnetosphere.How does a compass work?
The Earth is a magnet that can interact with othermagnets in this way, so the north end of a compass magnet isdrawn to align with the Earth's magnetic field. Because the Earth'smagnetic North Pole attracts the "north" ends of other magnets, itis technically the "South Pole" of our planet's magneticfield.What is the outer core made of?
The core is made of two layers: theouter core, which borders the mantle, and the innercore. The boundary separating these regions is called theBullen discontinuity. The outer core, about 2,200 kilometers(1,367 miles) thick, is mostly composed of liquid iron andnickel.What causes the Van Allen Belts?
A Van Allen radiation belt is a zone ofenergetic charged particles, most of which originate from the solarwind, that are captured by and held around a planet by thatplanet's magnetic field. The discovery of the belts iscredited to James Van Allen, and as a result, Earth'sbelts are known as the Van Allen belts.Why does Mars have no magnetic field?
Mars does not have an intrinsic globalmagnetic field, but the solar wind directly interacts withthe atmosphere of Mars, leading to the formation of amagnetosphere from magnetic field tubes.Does Earth lose water to space?
A new study indicates that hydrogen from splitwater molecules has escaped into space. Althoughwater covers 70 percent of the Earth's surface,water is actually a rare substance that represents just 0.05percent of the Earth's total mass.How far out does the earth magnetic field extend?
The magnetic field of our planet -- otherwiseknown as the magnetosphere -- extends out to about 65,000kilometers (40,000 mi) above the surface of theplanet.What is magnetospheric plasma?
The plasmasphere, or inner magnetosphere, is aregion of the Earth's magnetosphere consisting of low energy(cool) plasma. It is located above the ionosphere. Theplasmasphere was discovered in 1963 by Don Carpenter from theanalysis of VLF whistler wave data.
