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 melting of the glaciers may be a phenomenon in which a threshold exists. Once the. threshold is exceeded, glaciers may melt at an exponential rate, regardless of climate. change, thus increasing water run off to oceans and sea level rise (self-reinforcing process. / cascading effect).
