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.
Where can they be found? Glaciers may exist only on two conditions: the first, which is quite obvious, is that the annual temperatures must be below zero for a certain period of the year, so that ice can be preserved, the second, which is less intuitive, but equally indispensable, is that a sufficient amount of snow required to form a certain mass of ice must fall.
