Thanks!

1. Cold, polar air sinks southwards and hot, tropical air rises northwards. This creates a boundary called a polar front
2. Warm air is drawn to the centre of low pressure and cold air is sucked behind. This causes the depression to rotate anticlockwise and produces clouds and precipitation
3. The cold air begins to undercut the warm air in the 'warm sector'.
4. Eventually, the cold front catches up with the warm front to form the boundary called an occluded front.
5. Soon after the depression disappears.

This is what I would but but you might want to double check with the mark scheme because I haven't done a question to do with depression formation yet. I hope this helps anyway.
