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.
NYS Invitational Science Olympiad April 2005 6 Figure 14: Glacial Movement Base your answers to questions 31-35 on the three maps below. The maps show the ice movement and changes at the ice front (terminus) of an alpine glacier from the years 1874 to 1882. Points A, B, C, D, and E represent the positions of large markers placed on the glacial ice and left there for the 8 year period. The position of the glacial ice front for 1874, 1878, and 1882 is indicated on each map. Figure 14: Retreating glacier.
