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 former are to be found in the high latitudes, the latter in the lower latitudes, but at high levels, where the air becomes cool because of the altitude, and the heat of the low latitude is compensated by this effect : temperate glaciers are the glaciers we find in the Alps, but also particular glaciers as those which can be found in tropical or equatorial areas, such as the glaciers of Mount Kilimanjaro or Mount Kenya in Africa, or the glaciers in the Peruvian and Bolivian Andes.
