when a scientist says that a glacier flows, the scientist means that: group of answer choices the ice is under so much pressure that it implodes and falls downhill, like an old football stadium being blown apart by demolition experts. the ice is so cold that it is brittle, and breaks into chunks that roll downhill like sand. the ice is so warm that it melts, and flows downhill like water before refreezing. the ice is almost warm enough to melt, and deforms slowly like hot iron in a blacksmith shop or a chocolate bar in your pocket.
