in colder countries the ground gets colder down in the ground as well. the water in the pipes then gets colder, and when water gets colder it expands. this expansion could cause the pipes to burst so they put them lower to stay warm.

A phenomenon called 'the anomalous expansion of water' takes place at a temperature just below 4 degrees celsius, where water; unlike other substances begins to expand instead of contracting, when being cooled.
Thus, in cold countries, when the temperature drops low, water in the pipes may expand and exert pressure on the walls, causing them to burst.
The earth is a bad conductor of heat and electricity. However, there may be pores and cracks on the surface through which air can pass and cause heat exchange through convection.
Thus, to avoid any chances of heat exchange, the pipes are laid deep under the ground so as to effectively use the insulating properties of the soil and prevent the bursting of pipes.
