Answer: The ice caps are already in water.
Explanation:
The ice packs in North Pole and the ice sheet in Antarctica are already in water. When they melt therefore, they are simply being converted from one state to another but the quantity is the same.
In other words, the volume that the ice occupied in the water becomes the volume of liquid added to the water so there is no net change in volume added leading to sea levels staying the same.
The pressure on the inner core is greater than on the outer core and the melting point of iron, and because the pressure effect is higher than the temperature effect, the inner core is solidified.
