Q. Consider the following statements:
1.Solar flares are a continuous stream of charged particles that are ejected from the Sun’s corona and released into space.
2.Geomagnetic storms are disturbances in Earth’s magnetic field caused by interactions between the solar wind and Earth’s magnetosphere.
3.Solar flares are caused by the gravitational interaction between the Sun and other celestial bodies in the solar system, leading to the sudden release of energy and radiation.
How many of the above statements are correct?
Answer: A
Notes:
Explanation –
Statement 1 and 3 are incorrect. Solar flares are sudden and intense bursts of energy and radiation that originate from the Sun’s surface or corona, often associated with magnetic activity in active regions or sunspots. Solar flares occur due to the entanglement, intersection, or rearrangement of magnetic field lines near sunspots. Solar winds are a stream of plasma particles that are ejected from the Sun’s atmosphere.
Statement 2 is correct. Geomagnetic storms are disturbances in Earth’s magnetic field caused by interactions between the solar wind and Earth’s magnetosphere.
