Final answer:
A polar front depression commonly moves from west to east, influenced by the prevailing westerly winds and the Coriolis effect.
Step-by-step explanation:
The polar front depression, also known as an extratropical cyclone, typically moves in a west to east direction. This movement is primarily guided by the prevailing westerly winds in the mid-latitudes. The rotation of the Earth also plays a role in this eastward movement due to the Coriolis effect. Additionally, the north pole of a compass needle points North. When considering objects moving within Earth's magnetic field, a positively charged object moving due west where Earth's magnetic field is due north will experience a force straight down. Conversely, a negatively charged object moving in the same direction would experience a force straight up.
