3.Doppler radars rely on signals returning to the station after bouncing off of precipitation.

True

 4.Sheet lightning typically occurs _____.

when wind moves the ionized channel between each return stroke

when a lightning flash occurs within a cloud or is obscured by intervening clouds

with cloud-to-ground lightning that does not provide rain

as a dart leader moving toward the ground deviates from the original path

on a hot, summer night when the overhead sky is clear

5.Typically, a lightning flash will have _____.

one bright return stroke carrying a negative charge upward into the cloud

one bright stepped ladder carrying a negative charge upward into the cloud

one return stroke followed by a stepped leader

one bright stepped leader carrying a positive charge upward into the cloud

a stepped leader followed by at least one return stroke
