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.
The earth's bulge at the equator is about 42 km). The oceans would move toward the poles, changing the geography of our planet. This would result in a huge equatorial super-continent and two large polar oceans, north and south. Most of northern hemisphere will be under water as would be the southern hemisphere.
