The atmosphere is heated both by the Sun and by the Earth's surface. Water radiates heat differently than land, so the air temperature over the ocean is usually different than the air temperature over land.

The difference in air temperature over land compared to over water causes convection currents in the atmosphere. How would a person at the beach experience these convection currents?


 A. They would feel that the sand is hot.
 B. They would feel wind as the air moves.
 C. They would feel the heat of the Sun.
 D. They would feel that the water is cold.


 B. They would feel wind as the air moves.

Dr. Ray has developed a new way to remove oil from wetlands in the event of an oil spill. To test his new process, Dr. Ray builds a scale model of a wetland in his lab and pours a small amount of oil into it. He then observes the rate at which his process is able to remove the oil from the model.

Why did Dr. Ray use a model?


 A. Because real wetlands are too large to be affected by oil.

 B. Because real wetlands are too complicated for his process to work.

 C. Because his model makes the process more complicated.

 D. Because dumping oil in a real wetland would be dangerous.


 D. Because dumping oil in a real wetland would be dangerous.
