Global Global warming Surfaces

AI Thread Summary

Dark surfaces do contribute to global warming by absorbing more solar energy compared to lighter surfaces that reflect it. The melting of large ice and snow areas, which reflect significant sunlight, exposes darker surfaces like oceans and land, further increasing heat absorption. This feedback loop accelerates global warming as more dark surfaces lead to higher temperatures. The discussion highlights the critical role of surface albedo in climate dynamics. Understanding these interactions is essential for addressing climate change effectively.

Do dark surfaces exposed to the sun really contribute to global warming?

Dark surfaces absorb more light while light surfaces reflect it. Extremely large areas of ice and snow reflect more light (and its energy) back into space than dark areas such as the ocean or ground that would be exposed if the ice and snow were to melt.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
