C. convection
Solar energy heats the surface of the Earth, including the ground, rocks, and even roadways. As the temperature of these surfaces increases, heat energy is released back into the atmosphere, forming a pocket of warm air. As the warm air pocket rises, it is replaced by cooler air. This process is responsible for many of the weather patterns in our atmosphere, and is known as A. evaporation. B. transpiration. C. convection. D. conduction.
C. The ocean moderates air temperatures.
Some coastal regions of the world have cooler summers and warmer winters than inland regions at the same latitude. What accounts for this difference in climates? A. Coastal areas receive more sunlight. B. Prevailing winds moderate the weather. C. The ocean moderates air temperatures. D. Coastal areas are always flat.
A. convection
Sunlight heats the ground, and the ground warms the nearby air. The warm air expands and rises, while cool air rushes in to take its place. The example above describes the process that generates many surface winds. Surface winds are an example of _______ in the Earth's atmosphere. A. convection B. conduction C. radiation D. condensation
D. They would feel wind as the air moves.
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 that the water is cold. C. They would feel the heat of the Sun. D. They would feel wind as the air moves.
