"Glacier movement" refers to the slow motion of ice down a slope or valley. It happens due to the force of gravity and causes the glacier to continuously change its shape and position over time. Full definition
He hopes to apply the same techniques to study lake drainage below other glaciers, to understand how water flow at the base affects overall glacier movement. (sciencedaily.com)
Modern day glacier movements happen due to a multiple factors. (csmonitor.com)
In this final graph we have calculated historic glacier movements during the last 3000 years. (wattsupwiththat.com)
