Glaciers are large sheets of ice that can extend for miles. Glaciers are located in the Arctic and Antarctica, with the largest glaciers appearing in Antarctica. Icebergs, on the other hand, are smaller pieces of ice that have broken off (or calved) from glaciers and now drift with the ocean currents.

Diffusion is the process whereby gaseous atoms and molecules are transferred from regions of relatively high concentration to regions of relatively low concentration.
