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.
If ablation is greater than accumulation, then the glacier has negative mass balance and will recede. Note: see Common Misconceptions in Glaciology. Glaciers always flow downslope under the weight of their own gravity.laciers always flow downslope, through the processes of deformation and sliding. Glacier flow, velocity and motion is controlled several factors (Jiskoot et al., 2011), including those listed below: 1  Ice geometry (thickness, steepness),
