______26. An abnormal progressive rise in the water level
of a stream that may result in the overflow by the water of
the normal confines of the stream.
______27. a narrow, violently rotating column of air that
extends from a thunderstorm to the ground.
______28. It is referred to the gravitational pull between
the Earth and the moon.
