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.
The position of the front may not move. The two different air masses are then said to be separated by a stationary front. Although the two air masses are not moving, warm air may still rise over the cold air. The slope of a stationary front is as gentle as the slope of a warm front. Weather conditions, too, are similar to those of a warm front.
