Metamorphic rocks are created from existing rocks that undergo heat and pressure without melting. If rocks do melt, they would typically form igneous rocks, not metamorphic rocks.
Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.

Glaciers or moving, shifting and melting constantly. The worst that could happen is if too meltwater was created by the melting glacier it would cause a flood downstream.
