a. urbana
b. st. louis
c. milwaukee
d. austin

c. Milwaukee

Explanation:

The warmer the air gets, the higher its capacity for water vapor. Thus, the relative humidity would increase as the dew point temperature decreases and vice versa. The relative humidity is usually highest at sunrise at the point when the overnight low temperature is usually close to the dew point.

Since Milwaukee has the lowest Td = 21°F and its R.H = 51.358, a value higher than the rest since the rest have negative values.

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.
