Explanation:
an air mass is a body of air with relatively constant temperature and moisture content over a significant altitude are message typically covered hundreds thousands or millions of square kilometres a front is the boundary at which two air masses of different temperature and moisture content meet
I do not believe Scruffenbury Hill is a real place, as my instincts and google tells me. I could be wrong though. :/
<h2><u>
Relation between buoyancy, isostatic equilibrium, and epeirogenic processes</u></h2>
Buoyant force or buoyancy, is the force exerted in an object which is fully or partially occupied in a fluid. Isostatic equilibrium is the gravitational equilibrium between earth's crust and underlying mantle. while epeirogenic process is the depression of land having long wavelengths.
Both epeirogenic process and isostatic equilibrium uses the principle of buoyancy. The crust of the Earth or the lithosphere floats over underlying mantle at an elevation depending upon its density and thickness.
