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.
If a hurricane (northern hemisphere) rotates in one direction and a cyclone (southern hemisphere) rotates in the other, what happens if they cross the equator? They never cross the equator, nor do they occur near it. Hurricanes and cyclones are born in waters at least eight degrees north or south of the equator. The rotation of the earth sends them off on a track that arcs away from the equator.
