Walter forgot to wear his shoes on a sunny afternoon in August. He has to walk across the asphalt parking lot to get home. Which of the following will most likely take place if Walter crosses the parking lot?

A) There is no matter present for heat to move from 

     the asphalt to Walter’s feet.

B) Heat moves from warmer to cooler matter 

     through conduction, and Walter’s feet will absorb 

     the heat.

C) Convection will cause heat to transfer from

     Walter's feet to the asphalt because he is in 

     direct contact with the asphalt.

D) Asphalt is not a good heat conductor because it is

    heated by radiation, and the heat will not be

     transferred to Walter’s feet.

B) Heat moves from warmer to cooler matter 

     through conduction, and Walter’s feet will 

      absorb the heat.

Which of the following best explains how a sea breeze develops?

A) A sea breeze blows from the land surface 

     towards the sea because seawater heats up 

     more slowly than the land surface.

B) A sea breeze blows from the land surface 

     towards the sea because seawater heats 

     up more quickly than the land surface.

C) A sea breeze blows from the sea towards 

    the land surface because the seawater heats 

    up more slowly than the land surface.

D) A sea breeze blows from the sea towards the 

     land surface because the seawater heats up 

     more quickly than the land surface.

C) A sea breeze blows from the sea towards 

    the land surface because the seawater heats 

    up more slowly than the land surface.

    significant air temperature increases by 

    analyzing ice samples from the South Pole.

D) Scientists use computer models predicting an

     increase in the temperature of Earth's

     atmosphere to explain global warming to the 

     public.
