Dear Alanah,
Sorry for the late reply.
I've been away. If you didn't get the answer from your local school or
public librarian, here is one definition:
Convection currents are circular currents or movement within a liquid (or
gas) due to different densities of the hotter and cooler parts.
I got this from:
http://www.northstar.k12.ak.us/schools/joy/denali/DAuria/density_convect.html
where there is more information.
