If sea level has risen by 20 cm over the past century on the coast of North America,by how much do you think it has risen over the past century on the coast of India?Explain.
My first order guess would be 20 cm. If it went up more here than there, the water would tend to run from here to there and reach equilibrium over a century.
HOWEVER, in areas where for example glaciers are melting, it may look like the ocean level is going down because the earth rises as the weight of the ice is taken off it. In areas where tectonic forces are causing the earth to rise, such as northern India, it may look like the ocean level is going down, again because the land is rising.
thanks:-) i know you can answer it..
