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.
Meltwater can create landforms through both erosion and deposition, and the environment is highly dynamic and in constant flux. Meltwater moves in many ways through a glacier, water can move on the glaciers surface (supraglacial channels), within the ice (englacial channels) and under the ice (subglacially).
