Basic Questions About Depressions

[chris1969]

Hello everyone

I'm a weather beginner and I'm trying to get to grips with what causes weather fronts and depressions. After researching various websites I've a couple of very basic questions.

1) Depressions are commonly associated with a sequence of of warm and cold fronts. However are all depressions caused by fronts or can you get different sorts of depressions?

2) Depressions are caused by rising air leading to low pressure but what is it that causes the rising air? I understand how fronts develop from the interaction of polar and tropical air masses, but not what would cause air to rise in the absence of a frontal system.

Thanks in advance for your help with my beginner questions. :lol:
