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.
Glaciers And Glaciation By definition a glacier is a mass of ice composed of compacted and recrystallized snow that flows under its own weight. This makes glaciers very effective agents of erosion, transportation and deposition of sediment. The two types of glaciers are Valley or Alpine glaciers Continental glaciers.The difference between them is where they flow. Valley glaciers flow in mountain valleys from high to low elevations. Continental glaciers or ice sheets flow over vast unconfined land areas.Valley glaciers are present at high altitude in mountain valleys of Alaska, the Italian Alps and New Zealand.lacial Drift. All sediment deposited by a glacier whether its a valley glacier or continental ice sheet, is called glacial drift. Till: unstratified sediment deposited directly by glacial ice. It is poorly sorted & contains large boulder, pebbles clay-sized particles.
