The Moon will pass between the Sun and the Earth during the celestial event and it would keep the sun block for one and half hour. The Moon would cast two types of shadow while blocking the sun. These two shadows are called the umbral and penumbral shadow.

Kansas City, Nashville and St. Louis peoples have a chance to enjoy the total solar eclipse completely. It would be a great opportunity for the space enthusiasts to be part of this rare event.
