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.
The landforms that are produced by continental glaciers are of large extent. At the end of the glaciers sediments are deposited by moraines, but in contrast to valley glaciers that transport sediment at top and bottom, sediment transport in continental glaciers is mainly at the bottom.
