Breakwater, artificial offshore structure protecting a harbour, anchorage, or marina basin from water waves. Breakwaters intercept longshore currents and tend to prevent beach erosion.
photosphere. luminous, apparently opaque layer of gases that forms the visible surface of the sun sun,intensely hot, self-luminous body of gases at the center of the solar system.
The sun's photosphere is often mistakenly referred to as the surface of the sun. In reality however, the sun's photosphere is only a liquid-like plasma layer made of neon that covers the actual surface of the sun. solid surface model of the sun is a lot more logical and a lot better scientifically supported observationally than current gas models of the sun. More importantly, current gas models of the sun simply do NOT explain the video images we see through SOHO and TRACE.
