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.
Drain all the sinks and tubs in their house and see which way they swirl. Usually some sinks would drain clockwise and some counterclockwise, which means either it is a myth, or they live on the equator.. Dr. Doherty was joking about the equator part. But he explained that water can swirl either way anywhere on earth--and that which way it swirls is effectively random.
