explain the issues involved in inferring the overall regional direction of ice flow and striation and fabric data

Issues involve in inferring with the overall regional direction of ice flow.

Explanation:

Ice sheets are a thick boundary of ice mass moving at the rate of 2 or 3 cms per year. The implications of the current climate change on ice sheets are difficult to ascertain. Increasing temperatures are resulting in reduced ice volumes globally. Rising in sea levels increases the ice flow and the increase in global temperature takes place through the ice melt. Also, the regional changing wind speeds around the glaciers like in Antarctica have speeded the meltdown. Consequently, the erosion takes place on a large scale. A rise in temperature and the reduction of freshwaters creating more saline conditions around many regions of the world. Glacial striations are usually multiple, straight, and parallel, representing the movement of the glacier using rock fragments and sand grains, embedded in the base of the glacier, as cutting tools.
