Transcript of Sea Levels

Assignment: Exploring Sea Level Rise How do you think the melting of polar ice in its various forms will effect the sea level?
Will melting sea ice change the water level? Why or why not?
Will polar ice sheet melting change the water level? Why or why not?


From my knowledge of sea levels, I think that the melting of polar ice in its various forms will effect the sea level by increasing the level of water that fills the sea. As seen in the lab, once the ice melted inside of the bowl, it increased the water level without the rock inside of it. The bowl with the flat rock inside of it made the water level increase even more because the having the rock inside of the bowl is just like when you put ice cubes into a glass of water. When you put a solid object into a liquid, it increases the level, but not the amount of water. So it would appear that there was more water, but it is only the level of the water that increased. The melting of sea ice will change the water level. The reason is because with having the solid ice inside of the water that brings the level up just by having a solid in water. But once the ice melts, it's not only going to add to the water level, but it will add to the amount of water. But then again there could be a chance that the water level could go down because the water has a chance of spreading out and making the sea larger and making the water level decrease if there isn't a barrier to hold the water inside, just as the glass bowl does for the ice cubes in the lab. I do not think that ice sheets melting will change the water level. I think this because they aren't enough to take effect on the water level. But it could add to the amount of water that fills the sea. When you have a whole in the ground that you have filled up with water, when you add a little bit more water, it does add to the level, but then it flows over and spreads, and I feel that it could be the same way with the polar ice sheets affecting the sea level.
