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 advance and retreat of glaciers is controlled by considering the amount of ice added versus the amount lost during annual season if the amount of new snow ice added to the zone of accumulation is greater than the amount lost from the zone of wastage the glacier will grow or advanceresent day continental glaciers called ice sheets are found on antarctica greenland both ice sheets are over 3000 meters thick snow snow flakes and up to 90 % air at the surface granular ice 50 % compacted snow 50 % air
