Since the earth's axis is tilted 23 ½ degrees<span>, then on this particular day, the sun's rays are striking the earth directly at a latitude approximately </span>23 ½ degrees<span> north of the equator (that is, the sun's rays are coming in at an angle of </span>90 degrees<span> here; this is the subsolar point).</span>
Answer:
magnets are used in refrigerator to keep the door closed.
it is used in tv and computer screen.
magnets are also used in electrical bell.All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.Magnets are important because of their properties A particle moving in a magnetic field feels a force proportional to his speed, and to the field, so you can use a magnet that produce a field in a certain way and shape, in order to catch a particle in motion.

Answer:
Defined as below
Explanation:
Plate tectonics are defined as the pieces of Earth's crust floating over the liquid asthenosphere or the movements of sheets/plates of hard rock over the rigid mantle. Varying in thickness moving in the directions to there orientation. They are either oceanic or continental plates
Rift valleys are generally linear or are highlands that separated by actions of geologic agents. It may be formed by a divergent or a convergent plate movement. 0n earth can occur on all height above mean sea levels. Extraterrestrial Rift valleys have also been found on planets in the solar system. Example is Eastern valley of africa.
Earthquake is a shaking of the earth from the interior due to the vibrations and waves produced due to the movement of geo-material beneath the earth's crust. These waves are measured on a Richter scale and range from 1 to 12 caused by sliding of the earth plates from the convergent, divergent and transform boundaries. Like the ring of fire an earthquake prone region.
