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.
There are two types of glacial movement: sliders and creepers. Sliders travel along a thin film of water located on the bottom of the glacier. Creepers, on the other hand, form internal layers of ice crystals that move past one another based on the surrounding conditions (e.g. weight, pressure, temperature).
