1

Weather patterns like warm and cold fronts are examples of which form of thermal energy transfer?
a. Conduction
b. Radiation
c. All of these are correct
d. Convection

d. Convection
Solution: Convection is the transfer of energy between an object and its environment due to fluid motion. For example, the Sun heats the Earth warming the air at the surface. This warm air rises and cool air circulates in to take its place. The warm air cools as it rises and falls to Earth setting up a circulating flow of air which forms the basis of weather patterns.

c. Primary producer, primary consumer, secondary consumer, tertiary consumer, quartenary consumer
d. Primary consumer, tertiary consumer, quartenary consumer, primary producer, secondary consumer

c. Primary producer, primary consumer, secondary consumer, tertiary consumer, quartenary consumer
