Answer to Question #99218 in Field Theory for Kerry

Question

If global warming raises 1 degree how much would the world expand, and how far would the tectonic plates separate causing more earthquakes. Seems 2 percent would be even worse.

Answer 1

The global warming is due to rise of temperature of the earth/ world which is due to emission of green house gases like carbon dioxide, methane, CFC etc. due to various man made and natural activities. Man made activities is like the exhaust of gases through automobiles industries, thermal power project etc.

The net results is the rise of temperature of earth. The heat received from the sun is not auto radiated from the earth but captured in lower atmosphere is also the reason of rise of temperature. Due to global warming there is the rise of level of sea water.

Now due to rise of temperature, there is rise of heat which causes the expansion of world due to thermodynamic effect and given by formulae $Q=mc\nabla T$

m is the mass, c is the specific heat, del T is the rise of temperature, when del T is more Q is more expansion is more, there is more rise of sea level thus more effect on tectonic plates, thus more occurrence of tsunami
