Melting Under Pressure. This is Ken Ham, author and speaker on science and the Bible's authority. Water makes life possible on our planet, but there's another important process that makes water so unique. Consider the way that water comes together to form glaciers and snowballs. You know, when water freezes, it forms a framework or a lattice. And ice has an amazing way of dealing with pressure. For example, when you take a handful of snow and press it into a snowball, it isn't the heat from your hands that makes it stick together. The pressure from your hands breaks down the ice's framework and makes it melt slightly. It's this same process that allows glaciers to become slippery and then move over land. We live on the only planet known to have so much water, which is exactly what we'd expect from a creator god.
