A quick or sharp movement from the glacier could cause the crevasse. Fast increases in temperature or the overall global warming can cause the glaciers to form crevasses as well. Also in some cases water flows can cause or deepen crevasses.
Over time, the rocks are eroded and the weight of the overburden is lifted, so the rocks cool and are under less pressure, which causes the rock to change shape, often forming breaks. As the compression is lifted from the rocks, they are able to react to the tension on them by forming these breaks, or joints.
