How can a figure out which vocal part suits me best?

I have always enjoyed singing with others and in the shower like most people. I have been asked to join a choir. I think I would take vocal lessons. How is the decision made of which vocal part would suit me best. I am not entirely sure sometimes. Thanks for any responses.

Is there a difference between contralto and alto? If I sing between soprano and alto, what would I be? That is my question. Thanks.
