A glacial valley cross-sectional shape is a U shape whereas a stream valley is usually a V shape. The U shape comes from the scouring action of the alpine glaciers which carries rocks with it which can abrade the walls of the valley and the glacier occupies the whole valley so scours out such a shape whereas the stream cuts down and water washes in from the sides of the valley into the stream or river creating the V shape.
Answer:
100 yards
Explanation:
According to the security measures, all of the boats have to keep a distance of at least 100 yards. Apart from keeping this distance, the boats are also commanded to slow down when they are within 500 yards distance from the military vessels and ships. The reason for this measures is so that the boats don't get in trouble, and so that the military doesn't see them as a danger, seeming to be not obeying orders, or look like they are aggressive.
