Airwolf is the helicopter from the 1980s American eponymous television series. Its fictional features included stratospheric ceiling, stealth noise signature, a wide range of weapons and even supersonic speed. Airwolf was in fact a conventional Bell 222 helicopter modified by attaching some film props.
Hotspot (geology) In geology, a hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time.
First, there is a definition we need to make. Just to keep things straight, geologists use the word  magma  for molten rock that is still underground, and the word  lava  once it has erupted onto the surface. Rocks in the mantle and the core are still hot from the formation of the Earth about 4.6 billion years ago. When the Earth formed, material collided at high speeds. These collisions generated heat (try clapping your hands together-they get hot) that heat became trapped in the Earth.
