All of the statements are true about microbursts. The primary risk associated with microbursts is indeed wind shear, which causes the direction and/or speed of the wind to change dramatically. Wind shear is particularly dangerous during take-offs and landings because these are the critical phases of flight when pilots need to maneuver the aircraft to gain or lose altitude quickly. One of the causes of wind shear is a downburst from a convective cloud, which is a type of microburst.
