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.
Stationary front- a front that does not move or barely moves. Stationary fronts behave like warm fronts, but are more quiescent. Many times the winds on both sides of a stationary front are parallel to the front. Typically stationary fronts form when polar air masses are modified significantly so as to lose their character (e.g., cold fronts which stall). Figure 4 - Development of an Occluded Front: Occluded Fronts: Because cold fronts move faster than warm fronts, they can catch up to and overtake their related warm front. When they do, an occluded front is formed.
