Hip-hop dance originated from a cultural movement in 1970s New York. The movement also includes DJing, rapping, and graffiti. Hip-hop dance is very energetic, expressive and improvisational. Breakdancing is a good example of that: it is athletic and acrobatic. It combines spinning on your knees, head, hands, elbows and back. Hip-hop dance is the direct opposite of traditional dance forms such as ballet, jazz and tap.
Street dance evolved from hip-hop dance: the style originated on the streets and in clubs and it incorporates many dance styles. It is more accessible to everyone because it is not acrobatic. You can see it in the music videos of some very famous artists such as Justin Bieber, Justin Timberlake and others. Some people say street dance is a commercialised and simplified version of hip-hop.
