Which of the following is not true about simple magnets?

63% Answer Correctly

opposite poles repel each other

opposite poles attract each other

same poles repel each other

all of these are untrue


Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.


4

Small rocks shed by asteroids and comets that reach the earth are called:

60% Answer Correctly

meteoroids

meteors

meteorites

shooting stars


Solution

Smaller rocks shed by asteroids and comets are called meteoroids. When these rocks reach Earth's atmosphere, they burn up in the mesosphere and become meteors. If a meteor manages to reach the Earth, it is called a meteorite.


5

During continental drift, the drifting plates move across which of the following?

50% Answer Correctly

sediment

water

fault lines

liquid mantle


Solution

The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.
