Which of the following is best associated with a mt air mass?

a relief from warm humid summer conditions in the us northeast
b hot, dry summer weather in the us southwest
c cold, dry conditions in winter in the us southeast
d flooding rains in winter along the southern part of the us pacific coast

B hot, dry summer weather in the US southwest

Explanation:

A maritime air mass is associated with the warming of the air above the latitudes of United state's western and southern hemispheres. These winds bring warm, moist and unstable and originate in the Gulf of Mexico. Also, originate over the eastern Pacific in summer.  Thus due to the development of high-pressure areas over the northern hemisphere and thus winds move in the downward low-pressure areas.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
