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.
Within the glacier, the ice still flows. It acts as a conveyor belt to carry rock debris to the end of the glacier. When the ice there melts, it deposits the debris and forms a ridge (an end moraine). The longer the glacier remains stationary, the larger the end moraine grows.
