0:10:05 > 0:10:07Hi, everybody, and welcome to Science Fiction,
0:10:07 > 0:10:10the show where we take your questions on science...
0:10:10 > 0:10:12..and magnify them before your very eyes.
0:10:12 > 0:10:15Today's question, please, BUD E.
0:10:15 > 0:10:16Oh, all right, love.
0:10:16 > 0:10:19Just calibrating me calibrator there.
0:10:19 > 0:10:22Today's question comes from Miley in Killiney...
0:10:27 > 0:10:29The easiest way to understand waves
0:10:29 > 0:10:32is to think of a Mexican wave in a football stadium.
0:10:32 > 0:10:35Not that type of Mexican wave, you clown!
0:10:35 > 0:10:38As you know, a Mexican wave travels round a stadium
0:10:38 > 0:10:40but no-one actually moves.
0:10:40 > 0:10:42So the wave is like a big, invisible ball of energy
0:10:42 > 0:10:44moving along through the crowd.
0:10:44 > 0:10:47And it's much the same for the waves in the sea.
0:10:47 > 0:10:49It's just energy moving through the water.
0:10:49 > 0:10:52And that's where the monsters come in, Miley,
0:10:52 > 0:10:55swimming down in the depths of the ocean, with huge, big feet.
0:10:55 > 0:10:58Creatures like Jasconius, the island whale,
0:10:58 > 0:11:00Squirticus, the ink-spitting squid,
0:11:00 > 0:11:02Foul Fidel, the farting mermaid...
0:11:02 > 0:11:05Professor! Those are just stories.
0:11:05 > 0:11:06What do you mean?
0:11:06 > 0:11:10Waves are caused by the effect of the wind blowing over the water,
0:11:10 > 0:11:15the moon's gravitational pull on the Earth which causes the tides,
0:11:15 > 0:11:19and underwater volcanoes and earthquakes that cause big tsunamis.
0:11:19 > 0:11:23So now you know, Miley, waves aren't caused by the monsters in the sea.
0:11:23 > 0:11:26Sure that's just a load of old science fiction.
0:11:30 > 0:11:32It's time to wave goodbye now.
0:11:32 > 0:11:35Ha! See, I'm waving. Do you get it? Wave, ha!
0:11:35 > 0:11:37Priceless, huh? Priceless.
