#ExpeditionAlpine

During early July, the Anturus team travelled to the Alps to investigate the processes and science behind glaciers.

They looked at erosion, avalanches, glacial water and at the technology that allows them to get there. The team will also make activities and a series of educational videos for schools.

Every activity includes introduction and conclusion videos with a comprehensive, printable worksheet.

Ice Caves and Ice Lakes form when the melting snow on a glacier starts to melt its way through to the inside of the glacier itself.

In this experiment, Huw explains how water flow affects the formation of ice caves.

Ice is an interesting material. It is a solid that will fracture under pressure, but that can flow like a liquid.

In a glacier, crevasses will form if there are stresses on the ice, such as when it flows over an incline or when the glacial valley narrows and the ice is squeezed tight.

When a rock falls and then rests on a glacier, its weight causes pressure to build up on the ice beneath it. This pressure causes the ice to melt, allowing the rock to sink into the glacier, with the melt water displaced up and around the rock.

This process of ice melting of ice due to pressure and then refreezing is called regelation.

Glaciers are formed when snow falling on a mountain is slowly compacted under the pressure of it’s own weight whereas icicles are often produced by moving meltwater, especially slowly dripping water.

Neil introduces an experiment which explains why these types of ice look so different and shows you how to make an icicle.
