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.
Convection is the transfer of energy (heat) from one area to another area. The Law of thermodynamics explains that warm water will move towards the cold water to reach equilibrium. The cycle consists of water equatorial water turning to the right (in the N. hemisphere) and towards the poles where the cold currents are located. Give a real-life example of the 3 energy transfers and how they are connected.
