A: Flowering of onions can be caused by several things, usually temperature fluctuation. An onion is classed as a biennial which means it usually takes two years to go from seed to seed. However, this condition is triggered by temperatures.
Under what conditions will the front of a glacier remain stationary? Glacial fronts remain stationary when melting and snow accumulation are equal. Glacial fronts remain stationary when friction exceeds gravity forces. Glacial fronts remain stationary when melting and snow accumulation are unequal. Glacial fronts remain stationary when gravity forces exceed friction.
Every glacier has an accumulation zone and an ablation zone. Between them lies an equilibrium line where accumulation occurs as fast as ablation. Not only do these zones vary in size, but it's possible for one zone, such as the zone of ablation, to cover an entire glacier; that could happen in a warm year.ccumulation happens on a glacier's upper regions in the accumulation zone. Composed mainly of ice with very little new snow, the ablation zone lies at lower altitudes where the glacier is melting, sublimating, or calving, resulting in mass loss.
