The greatest portion of tornadoes form on the central plains of the United States in a region called Tornado Alley.
The energy of the sun is produced by the process of nuclear fusion, and a portion of this energy reaches the Earth in the form of sunlight, which heats the Earth.
During the early formation of the Sun, massive amounts of hydrogen and other "space" debris were coalesced together to form a protostar [See related link]. As more and more "stuff" was collected, the pressure in the centre of the protostar increased. When it reached a temperature of about 10 million degrees kelvin, nuclear fusion started. In nuclear fusion, hydrogen is fused into helium in a fairly inefficient rate (Something like 0.07%) giving heat off as a by product. This temperature dictates the size and colour of the Sun.

The outer portion of the shadow is called the "penumbra".

Eighth Avenue, aka Central Park West. The portion of 8th Avenue that borders the park is called Central Park West, the portion of 110th Street that borders the park is called Central Park North, and the portion of 59th Street that borders the park is called Central Park South. However, for some reason, the portion of 5th Avenue that borders the park is not called Central Park East.
