A shadow is a surface light cannot touch or reflect off of. Usually shadows appear when the main object is covering a light source. For example, lunar eclipses. Lunar eclipses cause a shadow over Earth because they block the main light source, The Sun from our point of view, casting a giant shadow over Earth.
