Choose the best possible answer to the following questions about Key Concept 2 "Formation and movement of glacial ice." The power of #MeToo, though, is that it takes something that women had long kept quiet about and transforms it into a movement. Edit. Around 600 to 800 million years ago, geologists think that almost all of the Earth was covered in snow and ice, called the Snowball Theory. He not only showed that the glacier had moved appreciably within a year, he also showed that it did so by plastically deforming itself or PLASTIC FLOW. false: Term. c.

Milankovitch Cycles, the Earth's orbit, the Earth's tilt, the Earth's wobble. The rock fragments freeze to the bottom of the glacier, gouging and scratching the bedrock as the glacier advances in the process of abrasion. 'Normal' flow rates are in feet per day. The Beardmore Glacier is best known as the route taken by early explorers in their efforts to trek from the coast, inland, to the South Pole. Accumulation of snow is greater than wastage. During the Ice Ages, glaciers covered as much as 30 percent of Earth. Save. Next Worksheet. Meltwater at the bottom of the glacier helps it to glide over the landscape. A glacier (US: / ˈ ɡ l eɪ ʃ ər / or UK: / ˈ ɡ l æ s i ər, ˈ ɡ l eɪ s i ər /) is a persistent body of dense ice that is constantly moving under its own weight. The intense pressure at the base of the glacier causes some of the ice to melt, forming a thin layer of subglacial water. (put in your own words).
