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 PHOTOSPHERE, the Sunâs visible surface, is the next layer of the Sun. The bubbling motion of the convection layer makes the granular patterns we see on the photosphere.The granules may look small in pictures, but scientists estimate they are really about the size of the Moon.hatâs HOT! The Sunâs next layer is the CONVECTION ZONE. Convection is how energy moves from the inner parts of the Sun to the outer pa rt of the Sun that we see. We can see convection when we look at a pot of boiling water.
