Glaciares en movimiento

Glaciers, massive ice formations on Earth for thousands of years, appear stationary but actually move due to their size and weight. The pressure at their base causes some ice to melt, forming meltwater that acts as a lubricant, reducing friction and allowing glaciers to advance. This movement is driven by gravity, and many glaciers are now moving faster than ever, up to 50 meters a day, constantly changing and advancing.

What is the significance of gravity in the movement of glaciers?

Discuss the current speed of glacier movement and its implications.
