GEOLOGY

Detailed explanation-1: -magnetosphere.gif. Earth is surrounded by a system of magnetic fields, called the magnetosphere. The magnetosphere shields our home planet from harmful solar and cosmic particle radiation, but it can change shape in response to incoming space weather from the Sun.

Detailed explanation-2: -The magnetosphere is the region of space surrounding Earth where the dominant magnetic field is the magnetic field of Earth, rather than the magnetic field of interplanetary space. The magnetosphere is formed by the interaction of the solar wind with Earth’s magnetic field.

Detailed explanation-3: -When the solar wind encounters Earth, it is deflected by our planet’s magnetic shield, causing most of the solar wind’s energetic particles to flow around and beyond us. This region that meets and blocks the solar wind is called the magnetosphere.

Detailed explanation-4: -A magnetosphere is that area of space, around a planet, that is controlled by the planet’s magnetic field. The shape of the Earth’s magnetosphere is the direct result of being blasted by solar wind. The solar wind compresses its sunward side to a distance of only 6 to 10 times the radius of the Earth.

Detailed explanation-5: -In the upper regions of the ionosphere, beginning several hundred kilometres above Earth’s surface and extending tens of thousands of kilometres into space, is the magnetosphere, a region where the behaviour of charged particles is strongly affected by the magnetic fields of Earth and the Sun.
