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 chromosphere is relatively thin region of the Sun thatâs just above the photosphere. Plasma on the surface of the Sun. Image credit: Hinode. The photosphere is the region of the Sun that we see. It measures an average temperature of almost 5,800 kelvin and produces the visible radiation.This is the point where photons generated inside the Sun can finally leap out into space. The chromosphere measures just 2,000 km, and itâs just outside the photosphere.he photosphere is the region of the Sun that we see.
