A diagram with a brown square on the left, with a white, smaller rectangle on top. Inside the brown square, there is the text: Land ice raises sea level when it enters the ocean. There is an arrow coming from the left, white rectangle pointing down to the right blue box. On the right-hand side, there is a blue box, with a smaller white rectangle overlapping the blue box. Where the rectangle overlaps the blue box, there is a dashed line, forming a smaller rectangle inside the bigger rectangle. This is labelled with the following text: Submerged volume of sea ice is equal to volume of water when sea ice melts.
