    The document is an explanation text about auroras. It begins with a general statement that auroras are natural light displays in the night sky near the poles caused by collisions between charged particles from the sun and gas atoms in the atmosphere. It then provides a sequenced explanation of the process, describing how solar wind releases electrons and protons from the sun, which are guided by Earth's magnetic field to collide with gas atoms at the poles and release energy seen as colorful lights. Finally, it notes that auroras only occur near the poles because the magnetic field is stronger there, pulling in more solar particles.

    How Aurora Happens


    An aurora (Latin word mean “sunrise”) is natural light display in the sky in the
    poles (north and south) caused by the collision of energetic charged particles
    with atoms in the high altitude atmosphere. In the northern latitude, the effect is GENERAL
    known as aurora borealis (aurora: the goddess dawn, borealis: north wind). While
    in the Antarctic region, the effect is known as aurora australis. They illuminate the
    STATEMENT
    northern and southern horizon as greenish glow or sometimes faint red,
    occasionally blue but most often in fluorescent green. Auroras can be seen at
    night because their light is not as strong as the light of the day.

    The aurora phenomenon occurs when the sun produces solar wind. Solar wind
    is a stream of electrons and protons which are released from the sun due to the
    high kinetic energy. These particles are charged and contain energy, which means SEQUENCED
    they contribute to electricity. In other way, our planet is surrounded by a super-
    EXPLANATION
    sized magnetic sheath which is usually called the Magnetic Field of the Earth.
    Sometimes this solar wind hits the Earth. Some of these charged particles lead to
    the poles of the earth at a speed that keeps growing. The collision between these
    particles and atoms present in the earth’s atmosphere, it releases the energy that

    Unit 8/ kd 3.8/ xi ipa

    causes the formation of colorful auroras at the poles of the earth, which looks like
    a big circle around the pole.

    Why Aurora is only found in the earth’s poles? This is because the north and
    South Pole magnetic field is very strong compared to other regions. The poles of
    this magnetic field pull the protons and electrons from the solar wind. So the
    phenomenon is more common in the Polar Regions.

    However, sometimes the Aurora can also appear at the top of the mountain in
    a tropical climate, but this phenomenon is extremely rare. Aurora phenomena
    have been observed on other planets than Earth that have a magnetic field, such
    as Jupiter, Saturn and more recently Mars. It is believed to be a widespread
    phenomenon in the Solar System and beyond.
