TEMPERATURE AND DENSITY Watch the following video which will demonstrate how temperature affects water density. You can create this same experiment at home if you'd like- you need to freeze an ice cube with blue food coloring, have an insulated thermos of hot water, have a clear plastic box to observe, and have some red food coloring. 8. Which currents sank, the warm or cold currents? 9. In which direction did these currents flow along the bottom? 10. Which currents rose to the surface, the warm or cold currents? 11. In which direction did these currents flow along the top?12. Sketch a color diagram of what you observed: 13. Where is water the warmest in the world? Where is it the coldest? (info can be found here)THERMOCLINE The upper 1,000m of the ocean is typically the warmest, here water is warmed by the sun. Below this layer, water is very cold (0-4°C) and its temperature does not change. This region where temperature changes with depth is called the thermocline. Depending on where you are in the world, the thermocline can be very deep (1,000m) or may be quite close to the surface (
