16. One of the interpretations of modern climate change is that warming temperatures will cause glacial ice to melt, and in turn this will cause sea levels to rise. Below is a plot of sea level rise during the deglaciation from the last glacial maximum. This was caused by the melting of the ice sheets that covered much of northern North America, Europe. A) What was the rate of sea level rise in cm / yr between 15 and 7 thousand years ago?

A circle is inside a square. The radius of the circle is decreasing at a rate of 3 meters per day and the sides of the square are increasing at a rate of 3 meters per day. When the radius is 3 meters, and the sides are 16 meters, then how fast is the AREA outside the circle but inside the square changing? The rate of change of the area enclosed between the circle and the square is square meters per day. Submit Question
