A) The elevation finder can help you find out the elevation of land for a country, place or other location. You can even figure out the land elevation below the sea or ocean. You can do this by typing in an address, name of a place, coordinates etc., into the corresponding input fields above.
I saw an experiment in a small ramshackle museum in Ecuador on the equator. There was a sink on a stand. When it was placed a metre on one side of the equator the water circled clockwise as it drained, one metre on the other side the water drained anti-clockwise and when directly over the equator the water drained, straight down, with no rotation.
Brad Hanson, a staff geologist with the Louisiana Geological Survey, presents the argument of why--in theory--water going down the drain would indeed spin in different directions depending on which hemisphere you're in: The direction of motion is caused by the Coriolis effect. This can be visualized if you imagine putting a pan of water on a turntable and then spinning the turntable in a counterclockwise direction, the direction in which the earth rotates as seen from above the north pole.
