This weeks post is about the ice caps melting and so this cartoon is quite fitting!
We were to complete an inquiry experience where ice cubes were put into a glass of water and we had to observe until the ice melted. In this experiment the observation made was that there was no water that overflowed from the glass. This I attributed to the ice causing displacement in the water and when the ice melted it filled the displacement so no water could overflow from the glass.
Now if we say this is like the ice caps then "if the ice caps melt" then the sea level would not rise, RIGHT? Well, Not exactly!
Not all the ice on Earth is creating the same displacement like in the glass of water so the sea level would rise as a result. An example would be if all the ice that makes up Antarctica at the South Pole melted then the sea level would rise. The ice in South Pole is thick and does not float like in the North Pole so if it were to melt it would add to the water already there and make the sea level rise. Also with Greenland, if it melted then it would raise sea levels quite a bit based on my interpretation of the activity.
At the North Pole the ice is not as thick and it acts like the ice in the glass so if the Arctic Ocean melted it would not affect the sea levels at all, again this is based on my interpretation of the ice in the glass.
My questions to everyone:
Is my interpretation correct?
Does this activity really mimic real life with the south and north poles?
