Cis forCobblestones
Cobblestones are stones that were used to pave streets before concrete and asphalt were invented. They were typically smooth stones found in a riverbed. Because the stones could be all different sizes and were placed so they fit together without gaps, they have given rise to the phrase "cobbled together".
A cone is a shape with a round bottom that gets smaller as it goes until it reaches a point. If you cut a slice through a cone parallel to the bottom, it will be the same shape as the bottom. If you cut a slice through the cone vertically going through the top point, you will get a triangle.
Many things are cone shaped. volcanos tend to be cone-shaped, pinecones and pine trees like the ones in the picture are cone-shaped, and of course traffic cones are cone shaped.
A cyclone is a very large weather event, which has low pressure at the center with winds that go around the center point. Cyclones turn anticlockwise in the northern hemisphere and clockwise in the southern.
Gis forGramophone
A gramophone, or phonograph, is a device that was used for playing recorded sound from the 1870s through the 1980s. More recently, gramophones were called record players or turntables. Gramophones play records, large round, black platters.
The original gramophone did not need electricity to run, with the record being turned by winding it up, and the sound was amplified simply by the shape of the "horn" you can see in the picture at the top of the gramophone. The sound itself comes from the vibrations of a small needle, called a stylus, in a spiral groove on the surface of the record.
