Imagine this experiment: fill two buckets with water, one relatively cold and one hot. fill a third bucket with water of an intermediate, lukewarm temperature. put your left hand into the hot water, your right hand into the cold, and wait one minute. now quickly plunge both hands into the lukewarm water. try to predict what sensations of temperature you will feel in each hand. will they feel the same? why?

answer; the above statement is (true);

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
